The increase in their bill when they switch from their current phone plan to the unlimited plan will be $13.99.

The cost of the current phone plan is calculated as follows:

The cost of the current phone plan = $55 + $19 + $9.50

The cost of the current phone plan = $83.50

The cost of the unlimited plan will be:

The cost of the new unlimited plan = $85 + $12.49

The cost of the new unlimited plan = $97.49

The increase in their bill will be:

The increase in their bill = $97.49 - $83.50

The increase in their bill = $13.99

Explanation:

The segment (4x-9) units long is the midsegment of the triangle. This is because each endpoint is a midpoint of the slanted sides.

One property of midsegments is that it is half as long as the side parallel to it.

The (4x-9) side is half as long compared to the 6x side.

Rephrased another way: The 6x is twice as long compared to (4x-9)

We'll use this to set up the equation to solve for x.

6x = 2*(4x-9)

6x = 8x-18

6x-8x = -18

-2x = -18

x = -18/(-2)

x = 9 is the final answer

The unit rate that corresponds to the proportional relationship shown in the graph is: 4/3 cm/s.

A proportional relationship is a mathematical relationship in which two variables are directly proportional to each other, meaning that the ratio of their values is always constant. The unit rate of a proportional relationship is the constant of proportionality, also known as the coefficient of proportionality. It is a number that relates the two variables in the relationship and it is also the slope of the line in the graph representation of the relationship.

For example, in a proportional relationship of y = kx, where y and x are the two variables and k is the constant of proportionality, the unit rate is k. It tells us how much y changes for each unit change in x. For example, if k=2, then for each increase of 1 in x, y will increase by 2.

Using a point on the graph, (12, 16):

Unit rate = y/x = 16/12 = 4/3 cm/s.

Answer:

The correct inequality to represent this scenario is: C. 35 + 4x ≤ 75

Explanation: Penelope has a fixed fee of $35 to rent the kayak and an hourly fee of $4. To find the maximum number of hours she can rent the kayak, we need to find the value of x that makes the inequality 35 + 4x ≤ 75 true. In this inequality, 35 is the fixed fee and 4x represents the total cost of renting the kayak for x hours. To solve for x, we need to subtract 35 from both sides of the inequality to get 4x ≤ 40. Then, we need to divide both sides by 4 to get x ≤ 10. This means that Penelope can rent the kayak for a maximum of 10 hours.

Step-by-step explanation:

You can dilate a line centered at the origin by using its coordinates of origin.

Dilating a line centered at the origin is a useful tool in geometry. To do this, you need to first identify the coordinates of the origin, or (0,0). Then, you need to identify the equation of the line.

Once you have these two points, you can calculate the coordinates of the line when you multiply the equation by a certain number, which is known as the scale factor.

This scale factor will determine the amount of dilation that needs to be applied to the line. Finally, you can plot the new points on a graph and draw the line to see the new shape.

Based on the information provided, a) if X has a binomial distribution, n = 5 and p = 0.256. b) X can take values in the range of 0 to 5. c) The values of P(x) for x = 0, 1, 2, 3, 4 , 5 are 0.228, 0.392, 0.269, 0.093, 0.016, and  0.011 respectively. d) mean = 1.28 and standard deviation = 0.995.

a) If X has a binomial distribution n represents the number of tickets bought which is 5 and p represents the probability of winning a prize after taking a single ticket which is 0.256.

b) X can take values in the range of 0 to 5, which indicates the possible number of won tickets. Hence, x = 0, 1, 2, 3, 4, 5. c)

Using the binomial distribution formula, P (x) = nCx*p^x*(1 – p)^(n-x). Hence,

P(0) = 5C0*(0.256)^0*(1 – 0.256)^)(5-0) = 0.228

P(1) = 5C1*(0.256)^1*(1 – 0.256)^)(5-1) = 0.392

P(2) = 5C2*(0.256)^2*(1 – 0.256)^)(5-2) = 0.269

P(3) = 5C3*(0.256)^3*(1 – 0.256)^)(5-3) = 0.093

P(4) = 5C4*(0.256)^4*(1 – 0.256)^)(5-4) = 0.016

P(5) = 5C5*(0.256)^5*(1 – 0.256)^)(5-5) = 0.011

d) The mean and standard deviation of the distribution is given by:

mean = n*p = 5*0.256 = 1.28
