An ant colony is built by 200 ants. The number of ants triples each week. How many ants will be in the colony at the end of the eighth week?

Answers

Answer 1
To solve this problem, we need to use the formula for exponential growth:

N = N0 * 3^t

where N is the final number of ants, N0 is the initial number of ants, 3 is the rate of growth (since the number of ants triples each week), and t is the number of weeks.

We are given that there are initially 200 ants, so N0 = 200. We want to find N at the end of 8 weeks, so t = 8. Substituting these values into the formula, we get:

N = 200 * 3^8

N = 200 * 6561

N = 1,312,200

Therefore, at the end of the eighth week, there will be 1,312,200 ants in the colony.

The coefficients a, b and c are the solutions to the system of equations defined by the matrix in this problem.

Considering the matrix, the system of equations is given as follows:

7x - y - 3z = -63.-6y - 2z = -20.y + z = 6.

Multiplying the last equation by 2 and adding with the second equation, the value of y is obtained as follows:

Answers

Answer:

m∠6 = 50°

Step-by-step explanation:

We know that angles 3 and 6 are same side interior angles.  Whenever a traversal cuts through two parallel lines (AB and CD), the sum of the same side interior angles is always 180.

Thus, we can find the measure of ∠6 by subtracting the measure of ∠3 from 180:

m∠6 + m∠3 = 180°

m∠6 + 130° = 180°

m∠6 = 50°

What is the margin of error of the 99% confidence interval for the true mean monthly salary of all former students? Assume the population is normally distributed. Round your answer to two decimal places (the hundredths place).

Answers

Answer:

384.67

Step-by-step explanation:

The margin of error for the 99% confidence interval for the true mean monthly salary of all former students can be calculated using the formula:

Margin of error = z * (standard deviation / sqrt(sample size))

where z is the z-score associated with the desired confidence level (in this case, 99%), standard deviation is the population standard deviation (given as $550), and sqrt(sample size) is the square root of the sample size (15).

The z-score for a 99% confidence level can be found using a standard normal distribution table or calculator, and it is approximately 2.576.

Plugging in the values, we get:

Margin of error = 2.576 * ($550 / sqrt(15))

                ≈ $384.67

Therefore, the margin of error of the 99% confidence interval for the true mean monthly salary of all former students is approximately $384.67.

Answers

Answer:

Step-by-step explanation:

In the uniform distribution, the mean (7.5) is equal to the median (8), making it the data set where the mean is equal to the median.

The data set in which the mean is equal to the median is the uniform distribution. In the provided data set, the bars represent the heights of the distribution. In the uniform distribution, the heights are 8, 6, 6, 8, 7, 8, 6, 8, 8, 8.

To determine the mean and median, we first calculate the mean by summing up all the values and dividing by the total number of values:

(8 + 6 + 6 + 8 + 7 + 8 + 6 + 8 + 8 + 8) / 10 = 75 / 10 = 7.5The mean of the data set is 7.5.

To find the median, we arrange the values in ascending order:

6, 6, 6, 7, 8, 8, 8, 8, 8, 8

Since there are 10 values, the median is the average of the fifth and sixth values, which is (8 + 8) / 2 = 8.

It is worth noting that the other distributions mentioned, namely the normal distribution and the skewed right and left distributions, do not have the mean equal to the median.

Determine the equation of the parabola that opens up, has vertex (−4,−8), and has a focal diameter of 16.

Answers

The equation of the parabola is y= 1/255 (x+4)² -8.

Since the parabola opens up, the general equation of the parabola is of the form [tex]$y = a(x-h)^2 + k$[/tex], where the vertex is (h, k).

So, substituting the given vertex (h,k)=(-4,-8), we have y=a(x+4)²-8.

Since the focal diameter is 16, the distance from the vertex to the focus is [tex]$\frac{1}{4}$[/tex] times the length of the focal diameter. Thus, the focus is at a point [tex]$(h,k+p)$[/tex] where [tex]$p = \frac{16}{4} = 4$[/tex]

The equation of the directrix is y = k-p = -8-4 = -12.

Using the formula for the distance between a point (x,y) and the directrix y = k-p, we get:

|y- (k-p)| / √(1+a²)

= |y+ 12|/ (√1+a²)

= |x-h|

Since the focus is on the parabola, the distance from the focus to any point (x,y) on the parabola is given by:

[tex]$$\sqrt{(x-h)^2 + (y-k-p)^2} = |4p(x-h)|$$[/tex]

Substituting the values of (h, k,p), we get:

[tex]$$\sqrt{(x+4)^2 + (y+4)^2} = 16|x+4|$$[/tex]

Squaring both sides and simplifying, we get:

[tex]$$(y+4)^2 = 256(x+4)^2 - (x+4)^2 = 255(x+4)^2$$[/tex]

[tex]$$(y+4)^2 = \frac{1}{255}(x+4)^2$$[/tex]

[tex]$$y+4 = \pm\frac{1}{\sqrt{255}}(x+4)$$[/tex]

Finally, substituting [tex]$y=a(x+4)^2-8$[/tex] and solving for a, we get:

a= (y+8)/ (x+4)²

Substituting this value of a in[tex]$y=a(x+4)^2-8$[/tex], we get:

y= (y+8)/ (x+4)²  (x+4)² -8

= 1/255 (x+4)² -8.

Shianne and Penelope are planning to repaint their house. They estimate the total cost to be $3499.58. They decide to pay 40% up front and finance the balance at 10% interest for 24 months. What is the monthly payment (m)? (Round your answer to 2 decimal places, and type in the dollar sign $ in front of it)

Answers

The monthly payment is approximately $95.63.

To find the monthly payment, we need to calculate the balance after the upfront payment and then determine the monthly payment required to finance that balance over 24 months with 10% interest.

The upfront payment is 40% of $3499.58:

Upfront payment = 40% * $3499.58 = $1399.83

The balance to be financed is the remaining amount after the upfront payment:

Balance = $3499.58 - $1399.83 = $2099.75

To calculate the monthly payment, we can use the formula for monthly payments on a loan:

m = (P * r * (1 + r)^n) / ((1 + r)^n - 1)

Where:

P = Principal amount (balance)

r = Monthly interest rate

n = Number of monthly payments (24)

The monthly interest rate is 10% divided by 12 (for 12 months in a year):

r = 10% / 12 = 0.10 / 12 = 0.00833333 (rounded to 8 decimal places)

Plugging in the values:

m = ($2099.75 * 0.00833333 * (1 + 0.00833333)^24) / ((1 + 0.00833333)^24 - 1)

Evaluating the expression:

m ≈ $95.63 (rounded to 2 decimal places)

Therefore, the monthly payment is approximately $95.63.

B.g(x) = -2|x - 3
C.g(x) = |x - 21 - 3
D.g(x) = 3x + 2)

Answers

The new function in terms of g(x) is g(x) = -2|x - 3).The correct answer is option B.

To understand why, let's break down the transformation step by step:

1. Translation Down by 3 Units: This means shifting the graph of the function downward by 3 units. To achieve this, we subtract 3 from the original function's expression, resulting in f(x) - 3 = |x| - 3.

2. Vertical Stretch by a Factor of -2: A vertical stretch affects the magnitude of the function's output. When we stretch a function vertically by a factor of a, we multiply the function's expression by that factor.

In this case, the factor is -2. Multiplying the translated function from step 1 by -2, we get -2(|x| - 3), which simplifies to -2|x - 3|.

Therefore, the new function, in terms of g(x), is g(x) = -2|x - 3).

Option B correctly represents this transformation by subtracting 3 inside the absolute value and multiplying the entire expression by -2.Option A does not incorporate the vertical stretch factor of -2, while option C includes an additional unnecessary shift. Option D represents a different linear function, not the translated and stretched absolute value function.

Answers

The parabola intersects the x-axis at the point (4.5, 0), and the x-intercept is 4.5.

To find the x-intercepts of a parabola, we need to determine the values of x where the graph intersects the x-axis. At the x-intercepts, the y-coordinate is always 0.

Given the information about the parabola falling from the left, passing through the point (3, 2), rising to the right, and passing through the point (6, 2), we can determine the equation of the parabola.

Since the parabola is symmetric, we can find the axis of symmetry (x-coordinate of the vertex) by taking the average of the x-values of the two given points:

x-coordinate of the vertex = (3 + 6) / 2 = 4.5

Now, we know the vertex of the parabola is (4.5, 0).

The equation of the parabola can be written in vertex form as follows:

y = a(x - h)^2 + k

where (h, k) represents the vertex. Since the vertex is (4.5, 0), we have:

y = a(x - 4.5)^2 + 0

Simplifying, we get:

y = a(x - 4.5)^2

To find the value of 'a', we can substitute one of the given points on the parabola. Let's use the point (3, 2):

2 = a(3 - 4.5)^2

2 = a(-1.5)^2

2 = 2.25a

a = 2 / 2.25

a = 8/9

Therefore, the equation of the parabola is:

y = (8/9)(x - 4.5)^2

To find the x-intercepts, we set y = 0:

0 = (8/9)(x - 4.5)^2

Setting each factor equal to zero, we get:

(x - 4.5)^2 = 0

Taking the square root of both sides, we find:

x - 4.5 = 0

Solving for x, we get:

x = 4.5

All of the given equations y = |x| + 3, y = x^2 + 3x, y = 2x + 1, and y = x^2 - 5x represent functions because they meet the criteria of assigning a unique output value to each input value.

A function is a mathematical relation that assigns a unique output value to each input value. To determine which of the given equations represent functions, we need to analyze if there is a unique output for each input.

(1) y = |x| + 3: This equation represents a function. For every input value of x, the absolute value of x is taken and then added to 3, resulting in a unique output value for each input.

(2) y = x^2 + 3x: This equation represents a function. The variable x is squared, multiplied by 2, and then 3 is added to it. Again, this process ensures that for each input value of x, there is a unique output.

(3) y = 2x + 1: This equation represents a function. It is a linear equation where the output (y) is determined by multiplying the input (x) by 2, then adding 1. The process guarantees a unique output for each input.

(4) y = x^2 - 5x: This equation represents a function. The input value of x is squared and then multiplied by x, and the result is subtracted from 5x. This equation follows the definition of a function, providing a unique output for every input.

D. The y-intercept is 40.5 the machine loses about 40.5 fluid ounces of diet soda each hour.

Answers

The y-intercept is 40.5 the machine starts with 40.5 ounces of diet soda.

Option B is the correct answer.

We have,

From the graph plot,

We see that,

The y-intercept is when x = 0.

This means,

At 0 hours, the amount of diet soda is 40.5.

Now,

y = 40.5 means the machine starts with 40.5 ounces of diet soda.

Thus,

The y-intercept is 40.5 the machine starts with 40.5 ounces of diet soda.

Determine whether events A and B are dependent or independent.

Answers

a. The events A and B are independent

b. The events A and B are independent

a. The events A and B are independent because the outcome of one event does not affect the outcome of the other event.

After selecting a penny, there are still dimes in the jar, and the probability of selecting a dime does not change.

b. The events A and B are independent because the day of the week does not affect the choice of shoe color.

The probability of selecting red shoes is the same for any day of the week.

The solution to the inequality is x < 3/14.

To solve the inequality -14x > -3 need to isolate the variable x on one side of the inequality sign.

We can start by dividing both sides by -14.

Since we are dividing by a negative number need to flip the inequality sign to maintain the direction of the inequality:

-14x/-14 < -3/-14

x < 3/14

The solution to the inequality is x < 3/14.

The solution by noting that 3 and 14 do not have any common factors so 3/14 is already in its simplest form.

The solution tells us that x is less than 3/14 means any value of x that is less than 3/14 will make the inequality true.

x = 0 x = -1 and x = -0.5 are all values that satisfy the inequality since they are less than 3/14.

We divide both sides of an inequality by a negative number need to flip the direction of the inequality sign.

This is because dividing by a negative number flips the sign of the inequality and we need to maintain the direction of the inequality to ensure that our solution is correct.

Ville and Olli have candies. If Ville gave Olli 7 candy, the boys would have the same number of candies. If, on the other hand, Olli were to give Ville 7 candy, Ville would have twice as much candy as Olli has. How many candies does each have? Ville has candies: Olli has candies: Check

Answers

Let's assume that Ville has x candies and Olli has y candies.

From the first statement, we know that if Ville gave 7 candies to Olli, they would have the same number of candies. This means that:

x - 7 = y + 7

Simplifying this equation, we get:

x - y = 14 ------ Equation 1

From the second statement, we know that if Olli gave 7 candies to Ville, Ville would have twice as many candies as Olli. This means that:

x + 7 = 2(y - 7)

Simplifying this equation, we get:

x - 2y = -21 ------ Equation 2

Now we have two equations with two unknowns, which we can solve using simultaneous equations.

Multiplying Equation 1 by 2 and subtracting Equation 2 from it, we get:

2(x - y) - (x - 2y) = 28 + 21

Simplifying this equation, we get:

x + 3y = 49 ------ Equation 3

We can now use Equation 1 to substitute for x in terms of y:

x = y + 14

Substituting this into Equation 3, we get:

(y + 14) + 3y = 49

Solving for y, we get:

y = 11

Substituting this value of y into Equation 1, we get:

x - 11 = 14

Solving for x, we get:

x = 25

Therefore, Ville has 25 candies and Olli has 11 candies.

To check, we can verify that if Ville gives 7 candies to Olli, they will both have 18 candies, and if Olli gives 7 candies to Ville, Ville will have 32 candies while Olli will have 4 candies, which satisfies both of the given conditions.

How to find the arc length

Central Angle: In geometry, a central angle is an angle formed by two radii (or line segments) that originate from the center of a circle and intersect at a point on the circumference.

Inscribed Angle: An inscribed angle is an angle formed by two chords of a circle that intersect at a point on the circle's circumference. The vertex of the angle lies on the circle, and the sides of the angle are the chords.

7. Arc XW

= 180 - 105

= 75 degrees

8. Arc VWY

= 75 + 105 + 85

= 265 degrees

A community sports league is raising money by making custom shirts to sell at league games. They plan to sell the shirts for $15. Each shirt costs $8 to make. They spent $55 for advertising.

Use n to represent the number of shirts they sell. Multiply this by the money they make for each shirt, then subtract the advertising cost.

Which expression represents the money that the league raises?

Answers



The expression that represents the money that the league raises is:

15n - 8n - 55

Explanation:

- The amount of money made for each shirt is $15, so to find the total money made from selling n shirts, we can multiply 15 by n, which gives 15n.
- The cost to make each shirt is $8, so to find the total cost of making n shirts, we can multiply 8 by n, which gives 8n.
- The advertising cost is given as $55, which needs to be subtracted from the total money made from selling the shirts.
- Therefore, the expression for the money that the league raises is 15n - 8n - 55.
