An airplane can reach a speed of 650 milers per hour. How long will it take the airplane to travel a distance of 1950 miles at top speed?

Answers

Answer 1

It will take the airplane approximately 3 hours to travel a distance of 1950 miles at its top speed of 650 miles per hour.

To find the time it will take for the airplane to travel a distance of 1950 miles at its top speed of 650 miles per hour, we can use the formula: time = distance / speed.

Plugging in the given values, we have:

Time = 1950 miles / 650 miles per hour

Dividing 1950 miles by 650 miles per hour, we can simplify the expression:

Time = 3 hours

Therefore, it will take the airplane approximately 3 hours to travel a distance of 1950 miles at its top speed of 650 miles per hour.

Answers

An inequality to represent the relationship between the amount they made and the number of large glasses they sold is C > P * L + 65

Let's denote:

L as the number of large glasses of lemonade sold,

S as the number of small glasses of lemonade sold,

C as the total amount made from selling lemonade ($250), and

P as the price of a large glass of lemonade ($4.00).

The total sales generated from selling small glasses of lemonade is given as $65.

We can set up an inequality to represent the relationship between the amount made and the number of large glasses sold as follows:

C > P * L + 65

In this case, the total amount made (C) should be greater than the product of the price of a large glass of lemonade (P) and the number of large glasses sold (L), added to the total sales generated from selling small glasses of lemonade ($65).

This inequality ensures that the amount made exceeds the revenue from selling the large glasses and the additional $65 from the small glasses.

Bert is planning to open a savings account that earns 1. 6% simple interest yearly. He wants to earn exactly $128 in interest after 2 years. How much money should he deposit?

Answers

To earn exactly $128 in interest after 2 years with a 1.6% simple interest rate, Bert should deposit $4,000 into his savings account.

Simple interest is calculated based on the initial principal amount, the interest rate, and the time period. The formula to calculate simple interest is:

Interest = Principal × Rate × Time

In this case, Bert wants to earn $128 in interest after 2 years with a 1.6% interest rate. Let's assume the principal amount he needs to deposit is P.

Using the formula, we can set up the equation:

$128 = P × 0.016 × 2

Simplifying the equation:

$128 = 0.032P

Dividing both sides by 0.032:

P = $128 / 0.032

P = $4,000

Therefore, Bert should deposit $4,000 into his savings account to earn exactly $128 in interest after 2 years with a 1.6% simple interest rate.

show that a8 contains an element of order 15

Answers

An element in a8, e^(iπ/4), that has order 15. Therefore, we have shown that a8 contains an element of order 15.

To show that a8 contains an element of order 15, we need to find an element in a8 whose order is 15.

First, note that the order of an element a in a group G is the smallest positive integer k such that a^k = e, where e is the identity element of G.

Now, consider the group a8, which is the group of all eighth roots of unity in the complex plane. The eighth roots of unity are given by:

1, e^(iπ/4), e^(iπ/2), e^(3iπ/4), e^πi, e^(5iπ/4), e^(3iπ/2), e^(7iπ/4)

To find an element of order 15, we need to find an eighth root of unity raised to a power that gives us a multiple of 15. We can see that e^(iπ/4) raised to the power of 15 gives us:

(e^(iπ/4))^15 = e^(15iπ/4) = e^(7iπ/2) = e^(3iπ/2) = -i

So, we have found an element in a8, e^(iπ/4), that has order 15. Therefore, we have shown that a8 contains an element of order 15.

A biologist measures the stride lengths of a population of emus, the second-tallest birds in the world, and the stride lengths of a population of ostriches, the tallest birds in the world. The biologist found that the stride lengths of both populations were approximately normally distributed.
• The mean stride length of the population of emus is 3 meters with a standard deviation of 0.5 meters.
• The mean stride length of the population of ostriches is 4.5 meters with a standard deviation of 0.75 meters.

o Approximately 34% of the ostriches have stride lengths between 4.5 and 5.25 meters. Describe these values in terms of the mean and standard deviation only. What interval would represent a similar percentage of emus?
o How can this percentage be seen using a graph of the normal curve?

Answers

The percentage can be seen on a graph of the normal curve by shading the area under the curve between the corresponding z-scores for the given interval.

For the ostrich population, the given interval of 4.5 to 5.25 meters represents one standard deviation above the mean (4.5 + 0.75 = 5.25) and includes 34% of the population.

Therefore, we can conclude that the mean stride length of the ostrich population is 4.5 meters, and the standard deviation is 0.75 meters.

To find a similar interval for the emu population, we can use the empirical rule for normal distributions.

This rule states that approximately 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations.

Using this rule, we know that approximately 68% of the emu population has stride lengths within one standard deviation of the mean, which is 3 meters ± 0.5 meters.

Therefore, a similar interval to the one given for the ostriches (4.5 to 5.25 meters) would be 3.5 to 4.25 meters for the emus.

The percentage of the ostrich population with stride lengths between 4.5 and 5.25 meters can be seen on a graph of the normal curve by shading the area under the curve between the corresponding z-scores. We can find the z-scores for the interval using the formula:

z = (x - μ) /

where x is the value of the upper or lower bound of the interval, μ is the mean, and σ is the standard deviation.

For the given interval of 4.5 to 5.25 meters for the ostrich population:

z1 = (4.5 - 4.5) / 0.75 = 0

z2 = (5.25 - 4.5) / 0.75 = 1

We can then use a standard normal distribution table or calculator to find the area under the curve between z = 0 and z = 1, which is approximately 0.34 or 34%.

To see this visually, we can plot the normal curve with the mean and standard deviation marked, and shade the area between the z-scores corresponding to the interval of interest.

A similar graph can be used to show the percentage of the emu population within a given interval.

Answers

The 98% confidence interval for the population mean time workers spend getting to work in the downtown area of Buffalo, New York, based on a sample of 15 workers, is between 16.03 and 26.63 minutes.

To calculate the confidence interval, we use the formula:

[tex]\bar{x} \pm t_{\alpha/2} \frac{s}{\sqrt{n}}[/tex]

Where x is the sample mean, tα/2 is the t-score with (n-1) degrees of freedom and α = 0.01/2 (since we want a 98% confidence interval), s is the sample standard deviation, and n is the sample size.

Plugging in the values from the given data, we get:

x = 21.13, s = 6.223, n = 15, tα/2 = 2.602

Thus, the confidence interval is:

[tex]$21.13 \pm 2.602 \cdot \frac{6.223}{\sqrt{15}}$[/tex]

= (16.03, 26.63)

7. If I || m. find the values of x and y in the diagram below. (7x-31) 63 | (5r-8) 63° (4y +27)* m 1 ​

Answers

Answer:

x = 13, y = 24.

Step-by-step explanation:

5x - 8 = 180 - (4y + 27)             (Internal alternate angles are congruent)

Also 4y + 27 =  63 + (7x - 31)    (External angle of a triangles theorem)

Simplifying the above 2 equations we get:

5x + 4y = 161  ........ (A)

7x - 4y  =  -5   ........ (B)

Adding A + B:

12x = 156

x = 13.

Now substitute x = 13 in equation A:

7(13) - 4y = -5

4y = 91 + 5 = 96

y = 24.

Answer:

x = 13

y = 24

Step-by-step explanation:

According to the Consecutive Interior Angles Theorem, when a straight line intersects two parallel straight lines, the resulting consecutive interior angles formed are supplementary (sum to 180°).

Therefore, as line l and line m are parallel, the angle marked (7x - 31)°, and the sum of the angles marked 63° and (5x - 8)°, are supplementary:

[tex](7x - 31)^{\circ}+63^{\circ}+(5x-8)^{\circ}=180^{\circ}[/tex]

Solve the equation for x:

         [tex]7x - 31+63+5x-8=180[/tex]

                              [tex]12x +24=180[/tex]

                      [tex]12x +24-24=180-24[/tex]

                                      [tex]12x =156[/tex]

                                     [tex]\dfrac{12x}{12} =\dfrac{156}{12}[/tex]

                                         [tex]x=13[/tex]

The exterior angle of a triangle is equal to the sum of the two non-adjacent interior angles of the triangle. Therefore:

[tex](7x - 31)^{\circ}+63^{\circ}=(4y+27)^{\circ}[/tex]

Substitute the found value of x into the equation and solve for y:

     [tex]7x - 31+63=4y+27[/tex]

 [tex]7(13)- 31+63=4y+27[/tex]

     [tex]91- 31+63=4y+27[/tex]

                   [tex]123=4y+27[/tex]

A. If P'Q'R'S' is formed by translating PQRS 4 units to the right and 5 units down, then PQRS is not necessarily equal to P'Q'R'S'.

Translation is a rigid transformation that preserves the shape and size of the original figure but may change its position.

B. If P'Q'R'S' is formed by reflecting PQRS over the x-axis and then over the y-axis, then PQRS is not necessarily equal to P'Q'R'S'.

Double reflection over perpendicular lines is equivalent to a 180-degree rotation, which may change the orientation of the original figure.

You spin a spinner that has 10 equal-sized sections numbered 1 to 10. find the probability of p(3)

Answers

Since the spinner has 10 equal-sized sections numbered from 1 to 10, the probability of landing on a specific number is determined by the ratio of the favorable outcomes (landing on the desired number) to the total possible outcomes (all the numbers on the spinner). The probability of landing on 3 is 1/10 or 0.1

In this case, we want to find the probability of landing on 3. Since there is only one section on the spinner labeled 3, the favorable outcome is 1.

The total number of possible outcomes is 10, as there are 10 sections on the spinner.

Therefore, the probability of landing on 3 is:

P(3) = favorable outcomes / total possible outcomes

P(3) = 1/10

So, the probability of landing on 3 is 1/10 or 0.1 (or 10% if expressed as a percentage).

Answers

The t-statistic for the observed slope is -0.764.

How to calculate the t-statistic for slope?

To calculate the t-statistic for the observed slope, we need to use the formula:

t = (b - β) / (SE(b))

where b is the estimated slope from the regression model, β is the hypothesized slope of 0.055, and SE(b) is the standard error of the estimated slope.

From the regression output in the problem above, we see that b = 0.0488 and SE(b) = 0.0089. Substituting these values and the hypothesized slope β = 0.055 into the formula, we get:

t = (0.0488 - 0.055) / 0.0089 = -0.764

Answers

The probability that the total travel time for the three deliveries will be at most 4 hours is approximately 0.9914, rounded to four decimal places.

Assuming that travel time follows an exponential distribution with mean 0.5 hours, the probability of travel time being less than or equal to a certain value t (in hours) is given by the cumulative distribution function (CDF):

F(t) = 1 - e^(-t/0.5)

We want to get the probability that the travel time for three deliveries, each involving a distance of 40 miles, will be at most 4 hours. Let X be the travel time for one delivery. Since the three deliveries are independent, the total travel time Y for the three deliveries is the sum of three independent and identically distributed exponential random variables, each with mean 0.5 hours.

F(y) = P(Y ≤ y) = ∫₀ʸ f(t) dt

where f(t) is the probability density function (PDF) of Y, which is:

f(t) = (1/0.5)^3 * t^2 * e^(-t/0.5) / 2!

The integral can be computed numerically or using software such as Excel, and the result is:

F(4) = P(Y ≤ 4) ≈ 0.9914

Therefore, the probability that the total travel time for the three deliveries will be at most 4 hours is approximately 0.9914, rounded to four decimal places.

The Progressives were a diverse group of people who held different beliefs and opinions, but many of them were committed to social justice and equality.

They recognized that segregation was a major problem in American society, and they worked to combat it through a variety of strategies.  

Some Progressives used their positions of power in government and the legal system to challenge segregation laws and practices. For example, Theodore Roosevelt, a Progressive president, appointed African Americans to federal positions and invited Booker T. Washington, a prominent African American leader, to dine at the White House.  

Other Progressives worked at the grassroots level, organizing protests, boycotts, and other forms of activism to challenge segregation in their communities. For example, the Niagara Movement, founded by African American intellectuals and activists, called for an end to segregation and discrimination.  

Despite their efforts, the Supreme Court decision in Plessy v. Ferguson in 1896 upheld the constitutionality of segregation, setting back the efforts of Progressives to combat segregation through the courts. However, Progressives and civil rights advocates continued to fight against segregation, eventually leading to the landmark Brown v. Board of Education decision in 1954, which declared segregation in public schools to be unconstitutional.

The population standard deviation is unknown.a. +- 3.202b. 0c. +- 3.625d. +- 3.707

Answers

The correct answer is (d) +-3.707. the population standard deviation is unknown and the sample size is less than 30, we use the t-distribution.

To find the critical value for a hypothesis test of the population mean when the population standard deviation is unknown and the sample size is less than 30, we use the t-distribution.

In this case, we have a sample size of 7, so the degrees of freedom are n-1=6. We want to test the null hypothesis that the population mean weight of newborn infants is 1011 pounds. The alternative hypothesis can be either one-tailed or two-tailed, but since the question does not specify, we will assume a two-tailed test with a significance level of 0.010.

Using a t-distribution table with 6 degrees of freedom and a significance level of 0.010, we find that the critical values are approximately +-3.707.

Therefore, the correct answer is (d) +-3.707.

Find all possible values for ZN to the nearest tenth of a degree.

Answers

The calculated possible value for ∠N in the triangle is 28.4 degrees

Finding the possible values for ∠N

From the question, we have the following parameters that can be used in our computation:

n = 24

p = 48

∠P = 108 degrees

The possible values for ∠N  can be calculated using the following law of sines

sin(N)/n = sin(P)/p

When the given values are substituted in the above equation, we have the following equation

sin(N)/24 = sin(108)/48

So, we have

sin(N) = 0.4755

Take the arc sin of both sides

N = 28.39

To the nearest tenth of a degree, we have

approximate the area under the curve y = x 3 from x = 0 to x = 2 using a right-endpoint approximation with 4 subdivisions. round your answer to two decimal places.

Answers

area under the curve y = x^3 from x = 0 to x = 2, approximated using a right-endpoint approximation with 4 subdivisions, is approximately 6.31 units squared

 approximate the area under the curve y = x^3 from x = 0 to x = 2 using a right-endpoint approximation with 4 subdivisions, we first need to divide the interval [0, 2] into 4 subintervals of equal width. The width of each subinterval is:

Δx = (2 - 0) / 4 = 0.5

Next, we evaluate the function at the right endpoint of each subinterval and multiply by the width of the subinterval, and then sum these products to get the approximate area:

approximate area = f(0.5)Δx + f(1.0)Δx + f(1.5)Δx + f(2.0)Δx
                = (0.5^3)(0.5) + (1.0^3)(0.5) + (1.5^3)(0.5) + (2.0^3)(0.5)
                = 0.125 + 0.5 + 1.6875 + 4
                = 6.3125

Rounding this to two decimal places, we get an approximate area of 6.31 units squared. Therefore, the area under the curve y = x^3 from x = 0 to x = 2, approximated using a right-endpoint approximation with 4 subdivisions, is approximately 6.31 units squared.

find the taylor polynomial of degree 4 for cos(x), for x near 0:

Answers

The Taylor polynomial of degree 4 for cos(x), for x near 0, can be found by expanding the function as a power series centered at x = 0.

The general formula for the Taylor polynomial of degree n for a function f(x) centered at x = a is:

Pn(x) = f(a) + f'(a)(x - a) + f''(a)(x - a)^2/2! + f'''(a)(x - a)^3/3! + ... + f^n(a)(x - a)^n/n!

For cos(x), we have:

f(x) = cos(x)

f'(x) = -sin(x)

f''(x) = -cos(x)

f'''(x) = sin(x)

f''''(x) = cos(x)

Evaluating these derivatives at x = 0:

f(0) = cos(0) = 1

f'(0) = -sin(0) = 0

f''(0) = -cos(0) = -1

f'''(0) = sin(0) = 0

f''''(0) = cos(0) = 1

Plugging these values into the general formula, we get:

P4(x) = 1 + 0(x - 0) + (-1)(x - 0)^2/2! + 0(x - 0)^3/3! + 1(x - 0)^4/4!

Simplifying the terms:

P4(x) = 1 - (x^2)/2! + (x^4)/4!

Therefore, the Taylor polynomial of degree 4 for cos(x), for x near 0, is:

P4(x) = 1 - (x^2)/2! + (x^4)/4!

Complete the program specified below. Once completed you are to upload your .java file, NOT an executable .jar file. When an object is falling because of gravity, the following formula is used to determine the distance the object falls in a specific time period: d = 1/2gt2 where d is the distance fallen, g is the gravitational acceleration, and t is the time in seconds. On earth, g is 9.8 meters/sec2. On the moon, g is 1.625 meters/sec2. Create a class file named Gravity.java with a method called distanceFallen that accepts the time of falling in seconds as an argument. The method returns the distance fallen as a number value with four decimal points of accuracy. The main method should demonstrate the distanceFallen method by creating a table that shows the distance fallen on the earth compared to the moon for time values 1 through 10. Use your formatting knowledge to make the table columns line up in the console.

Given: ABCD is a trapezoid. Prove: Angle ABC is greater than Angle D

Answers

One way to prove that angle ABC is greater than angle D is by using the fact that the angles in a triangle add up to 180 degrees. Here are the steps:

1. Draw a line segment from A to CD so that it is perpendicular to CD. Let's call the point where the line segment intersects CD point E.
2. Since AE is perpendicular to CD, we know that angle AEC is a right angle.
3. Since ABCD is a trapezoid, we know that angle ABD is congruent to angle BCA (since they are alternate interior angles).
4. Therefore, angle ABD + angle AEC = angle BCA + angle AEC.
5. Since angle AEC is a right angle, we know that angle ABD + 90 degrees = angle BCA + 90 degrees.
6. Simplifying this equation, we get angle ABD = angle BCA.
7. Since angle ABD is greater than angle D (since it is an exterior angle of triangle BCD), we know that angle BCA is also greater than angle D.
8. Therefore, angle ABC (which is equal to angle BCA) is greater than angle D.

Answer: The reason you could tell that angle ABC is greater is because if you connect abc and compare the sizes

Two weeks ago, Ace's bus route was 62.5% full. How many riders did
he have two weeks ago?

i DESPERATELY need this question!!!!1 will give brainliest
(also provide an explanation pls!!)

Answers

Ace had 0.625 or 62.5 riders two weeks ago.

Now, We can start by setting up a proportion:

fullness = riders / capacity

where the fullness is 62.5% or 0.625,

And, the capacity is 100% or 1 (assuming the bus is completely full at 100%).

Now, We can solve for the number of riders:

0.625 = riders / 1

riders = 0.625 x 1

riders = 0.625

So, Ace had 0.625 or 62.5% riders two weeks ago. If we assume that riders must be a whole number, we can round up to 63 riders.
