When you sign up for a movie service, you get three free months of movies. Then you are charged $15 per month to rent movies. If

podryga [215]

So your base equation would be y = 15x - 45
(The -45 is the free three months)
Then you would substitute 90 into the y position and solve, so your answer would be 9 months.

Charles begins finding the volume of a trapezoidal prism using the formula a = one-half(b1 b2)h to find the prism's base area. a

Orlov [11]

The volume of the trapezoidal prism having side lengths x, (x+2), (x+4) and height of 2x is 2x³+6x² option first is correct.

<h3>What is volume?</h3>

It is defined as a three-dimensional space enclosed by an object or thing.

We know the volume of the trapezoidal prism can be given:

$\rm V=\frac{1}{2} (a+b)\times h \times L$

Where V = The volume of the trapezoidal prism:

Length of the trapezoid L = x

Top width a = (x+2)

Base width b = (x+4)

Height of the trapezoidal prism h = 2x

$\rm V=\frac{1}{2} (x+2+x+4)\times 2x \times x$

$\rm V=\frac{1}{2} (2x+6)2x^2\\\\\rm V= (2x+6)x^2\\\\\rm V= (2x^3+6x^2)$

Thus, the volume of the trapezoidal prism is $\rm (2x^3+6x^2)$

Identify the sample space in the following tree diagram

VashaNatasha [74]

<h3>Answer: Choice B</h3>

There are 2 sides per coin, and 3 flips, so 2^3 = 8 total items in the sample space

HHH
HHT
HTH
THH
HTT
THT
TTH
TTT

Tracing each branch from left to right will help form the 8 different outcomes. For instance, if you go along the upper most path of the upper tree, then you'll get HHH meaning you got 3 heads in a row. The next branch down would be HHT, and so on.

The leaders of two youth sports teams randomly select five members of each team and record their ages, as shown.

Flauer [41]

Answer:

Members of Team A are likely older, and they have less variability in their ages.

Step-by-step explanation:

To solve this question, we need to find the mean and the standard deviation for each team.

Team A 16, 13, 12, 16, 13

The mean is:

$M = \frac{16 + 13 + 12 + 16 + 13}{5} = 14$

The standard deviation is:

$S = \sqrt{\frac{(16-14)^2 + (13-14)^2 + (12-14)^2 + (16-14)^2 + (13-14)^2}{5}} = 1.67$

Team B: 10, 13, 16, 16, 10

The mean is:

$M = \frac{10 + 13 + 16 + 16 + 10}{5} = 13$

The standard deviation is:

$S = \sqrt{\frac{(10-13)^2 + (13-13)^2 + (16-13)^2 + (16-13)^2 + (10-13)^2}{5} = 13} = 2.68$

Which statement appropriately compares the ages of the team members?

Sample of team A has higher mean age, which means that they are likely older. They also have a smaller standard deviation, so they likely have less variability in their ages.
