Answer:

Step-by-step explanation:

1   2/35 miles you run down the slope.

You run 8 2/5 miles in total, and you run 1/2 of that distance on a hill, so you run (1/2) x 8 2/5 = 4 1/5 miles on the hill.

You run down the slope for the last 2/7 of the hill.

To find how many miles that is, we can multiply the total distance on the hill by 2/7:

(2/7) x 4 1/5 = 1  2/35

Therefore, you run down the slope for 1  2/35 miles of your run.

Answer:

The value of the 8 in the number 1.803 is 0.08.

To find the value of the 8 in 81.30,

we can use the following process:

First, since 1.803 has three digits, we can assume that the value of each digit has a decimal place value of 0.001. So the 8 in 1.803 has a place value of 0.008.

Meanwhile, 81.30 has four digits. Therefore, the value of each digit has a decimal place value of 0.0001. So the 8 in 81.30 has a place value of 0.0008.

Therefore, the value of the 8 in the number 1.803 is greater than the value of the 8 in the number 81.30.

Therefore, the solution set for the system of inequalities is all integers less than -5 and less than 3.4.

To solve the system of inequalities, we need to find the values of 'a' that satisfy both of the given inequalities.

First, we will solve the first inequality:

3 - 2a > 13

Subtracting 3 from both sides, we get:

-2a > 10

Dividing both sides by -2 (and flipping the inequality since we are dividing by a negative number), we get:

a < -5

Now, we will solve the second inequality:

5a < 17

Dividing both sides by 5, we get:

a < 3.4

Therefore, the solution set for the system of inequalities is all integers less than -5 and less than 3.4. The integers that are in this solution set are -6, -7, -8, -9, -10, -11, -12, -13, -14, -15, -16, -17, -18, -19, -20, -21, -22, -23, -24, -25, -26, -27, -28, -29, -30, -31, -32, -33, -34, -35, -36, -37, -38, -39, -40, -41, -42, -43, -44, -45, -46, -47, -48, -49, -50, -51, -52, -53, -54, -55, -56, -57, -58, -59, -60, -61, -62, -63, -64, -65, -66, -67, -68, -69, -70, -71, -72, -73, -74, -75, -76, -77, -78, -79, -80, -81, -82, -83, -84, -85, -86, -87, -88, -89, -90, -91, -92, -93, -94, -95, -96, -97, -98, -99, -100, -101, -102, -103, -104, -105, -106, -107, -108, -109, -110, -111, -112, -113, -114, -115, -116, -117, -118, -119, -120, -121, -122, -123, -124, -125, -126, -127, -128, -129, -130, -131, -132, -133, -134, -135, -136, -137, -138, -139, -140, -141, -142, -143, -144, -145, -146, -147, -148, -149, -150, -151, -152, -153, -154, -155, -156, -157, -158, -159, -160, -161, -162, -163, -164, -165, -166, -167, -168, -169, -170, -171, -172, -173, -174, -175, -176, -177, -178, -179, -180, -181, -182, -183, -184, -185, -186, -187, -188, -189, -190, -191, -192, -193, -194, -195, -196, -197, -198, -199, -200, -201, -202, -203, -204, -205, -206, -207, -208.

We can predict that 375 shoppers are likely to return to the mall during the same week.

How to estimate the number of shoppers?

To estimate the number of shoppers who are predicted to return during the same week, we need to use the proportion of shoppers who come to the mall more than once a week in the random survey as an estimate for the proportion of all shoppers who come to the mall more than once a week.

From the random survey, we have:

Number of shoppers surveyed (n) = 120

Number of shoppers who come to the mall more than once a week in the survey (x) = 45

So the proportion of shoppers who come to the mall more than once a week in the survey is p-hat = x/n = 45/120 = 0.375

We can use this proportion to estimate the number of shoppers who come to the mall more than once a week in the population of 1,000 shoppers who visit the mall in one day,

predicted number of shoppers who come to the mall more than once a week = p-hat × population size

= 0.375 × 1000

= 375

Therefore, we can predict that 375 shoppers are likely to return to the mall during the same week.

The probability that  the Islanders will win at most one out of five games in a series against the Rangers is P ( A ) = 0.337

Given data ,

The probability that the Islanders will beat the Rangers in a game is 0.4

Now , The probability that  the Islanders will win at most one out of five games in a series against the Rangers is P ( A )

And , from the binomial distribution ,

P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ

On simplifying , we get

p = 0.4 (probability of the Islanders winning a single game)

n = 5 (number of games in the series)

Now we can calculate the probability of winning 0 or 1 game using the binomial probability formula:

P(X=0) = C(5, 0) ( 0.4 )⁰ (1-0.4)⁵

P(X=1) = C(5, 1) ( 0.4 ) (1-0.4)⁴

P(X=0) = 0.6⁵ ≈ 0.078

P(X=1) = 5 x 0.4 x 0.6⁴ ≈ 0.259

Now, to find the probability of winning at most one game, we add the probabilities of winning 0 and 1 game:

P(X ≤ 1) = P(X=0) + P(X=1) ≈ 0.078 + 0.259 ≈ 0.337

If the senior classes at High School A and High School B planned separate trips to the indoor climbing gym.  the number of students  a van  can carry is 18 students.

Let's start by using "v" to represent the number of students that can fit in a van, and "b" to represent the number of students that can fit in a bus. We can then set up a system of equations to represent the given information:

For High School A:

14v + 5b = 334 (equation 1)

For High School B:

3v + 10b = 393 (equation 2)

We know that every van has the same number of students as every bus, so we can set v equal to b:

v = b

We can then substitute b for v in either equation:

14v + 5b = 334

14b + 5b = 334

19b = 334

b = 17.58

We can round this to the nearest whole number since we can't have fractional students. So, a bus can carry 18 students.

Since v = b, we know that a van can also carry 18 students.

To find the perimeter of a polygon, we need to add up the lengths of all its sides.

The length of a side can be found using the distance formula, which is:

d = √[(x2 - x1)² + (y2 - y1)²]

Using this formula, we can find the lengths of the sides of triangle AMN:

d(MN) = √[(5 - 4)² + (-7 - 4)²] = √(1² + (-11)²) = √(1 + 121) = √122

d(NA) = √[(-6 - 5)² + (-6 - (-7))²] = √((-11)² + 1²) = √(121 + 1) = √122

d(AM) = √[(4 - (-6))² + (4 - (-6))²] = √(10² + 10²) = √200

So the perimeter of AMNO is:

P = d(MN) + d(NA) + d(AM) = √122 + √122 + √200 ≈ 24.3 (rounded to the nearest tenth)

Therefore, the perimeter of AMNO is approximately 24.3 units.

The likelihood that the friend will be late by between 10 and 30 minutes is roughly 0.6667, or 66.67%.

The probability that the buddy will be between 10 and 30 minutes late is equal to the size of the rectangle that exists between x = 10 and x = 30, and below the curve of the probability density function because the probability density function is uniform.

Given that the range of potential values for x is [0, 30] minutes, the height of the rectangle is equal to the greatest value of the probability density function, which is 1/30.

The width of the rectangle is 30 – 10 = 20 minutes, which is the difference between the interval's upper and bottom boundaries.

The likelihood that the friend will arrive between 10 and 30 minutes late is thus:

P(10 < x < 30) = (height of rectangle) x (width of rectangle)

= (1/30) x 20

= 2/3

The three inequalities that define the region R are:

y ≤ -2x + 6

x ≤ (2/5)y

x ≥ (3/2)y - (2/3)

An inequality is a statement that two values or expressions are not equal. In other words, it is a statement that one value or expression is greater than or less than another. Inequalities are commonly used to describe relationships between numbers or variables.

To write down the three inequalities that define the region R, we need to identify the equations of the three boundary lines that enclose the shaded region.

From the equations given, we can rearrange them to get the equations of the three lines:

2x + y = 6 => y = -2x + 6

2y = 5x => y = (5/2)x

3y + 2x = 4 => y = (-2/3)x + (4/3)

To determine the inequalities that define R, we need to figure out which side of each boundary line is the shaded region.

The line y = -2x + 6 is the upper boundary of R. To be inside R, we need y to be less than or equal to -2x + 6, so the first inequality is:

y ≤ -2x + 6

The line y = (5/2)x is the right boundary of R. To be inside R, we need x to be less than or equal to 2/5y, so the second inequality is:

x ≤ (2/5)y

The line y = (-2/3)x + (4/3) is the left boundary of R. To be inside R, we need x to be greater than or equal to 3/2y - 2/3, so the third inequality is:

x ≥ (3/2)y - (2/3)

Therefore, the three inequalities that define the region R are:

y ≤ -2x + 6

x ≤ (2/5)y

x ≥ (3/2)y - (2/3)

Each of these inequalities individually describes a half-plane, and their intersection is the shaded region R in the diagram.

The two correct representations of the inequality –3(2x – 5) < 5(2 – x) are:

-6x - 5 < 10 - x and -6x + 15 < 10 - 5x.

What is inequality?

An inequality in mathematics is a statement that indicates the relative size or order of two quantities or expressions, implying that they are not equal.

To solve the inequality, we can simplify it as follows:

-3(2x – 5) < 5(2 – x)

-6x + 15 < 10 - 5x (distribute the negative sign on the left and the positive sign on the right)

-6x + 5x < 10 - 15 (add 6x and subtract 15 from both sides)

-x < -5 (combine like terms)

x > 5 (multiply both sides by -1 and reverse the inequality)

Therefore, x > 5 is the solution to the inequality. The correct representations of this solution are:

-6x - 5 < 10 - x (simplified form of the original inequality)

An expression that can be used to find the amount of the greatest change in one hour include the following: C. -240 - (-80) meters.

In Mathematics and Geometry, the gradient, rate of change, or slope of any straight line can be determined by using the following mathematical equation;

Rate of change (slope) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Rate of change (slope) = rise/run

Rate of change (slope) = (y₂ - y₁)/(x₂ - x₁)

By substituting the given data points into the formula for the slope of a line, we have the following;

Rate of change (slope) = (y₂ - y₁)/(x₂ - x₁)

Rate of change (slope) = (-204 - (-80))/(2 - 1)

The points at which a line crosses an axis are known as the x-intercept and the y-intercept, respectively. We set y = 0 and compute the equation for x to determine the x-intercept.

This is due to the fact that the line crosses the x-axis at y=0. If an equation is not in the form y = mx + b, we can still solve again for intercepts by substituting 0 where necessary and then solving for the final variable. Set x = 0 and then solve for y to find the y-intercept.

20FT I DID THIS IN 7TH GRADEEEEEEEEEEEEEE

Step-by-step explanation:

There are 10 possible outcomes for the digit (0-9) and 26 possible outcomes for the letter (A-Z). Since the choices are independent, the probability of selecting a 6 as the digit and a consonant as the letter is the product of the probabilities of each event occurring separately.

There are 21 consonants in the English alphabet, so the probability of selecting a consonant is 21/26. The probability of selecting a 6 is 1/10.

Therefore, the probability of selecting a 6 and a consonant is:

P(6 and consonant) = P(6) × P(consonant)

= 1/10 × 21/26

= 21/260

= 3/40

Hence, the probability that the number is 6 and the letter is a consonant is 3/40.

Lena's total pay if she sells 29 copies of Math is Fun would be $4210.

Lena's total pay (P) to the number of copies of Math is Fun she sells (N) is:
