In a basketball game, the number of successful shots S that a player makes for each attempt A can be modeled by the equation S=0.5A+1.
Based on this equation, how many more successful shots can the player expect to make, on average, if she makes 10 more attempts in a game?

1

1

1

1

The slope represents the average increase in the number of successful shots if the number of attempts is increased by 1. Therefore, if the number of attempts is increased by 10, the number of successful shots will increase by 0.5(10) = 5 on average.

A group of high school students were surveyed about their future educational plans.
The results of the survey are shown in the table below:

Highest Education Level Student Is Planning to Complete / Number of Students
Complete a Technical Program: 18
Complete an Associate's Degree: 9
Complete a Bachelor's Degree: 32
Complete a Master's Degree or Higher: 4

If a student from this survey is randomly selected, what is the probability that the student plans to complete an associate's degree or a bachelor's degree?

0.1429

0.1429

0.1429

0.1429

The total number of students surveyed was 18 + 9 + 32 + 4 = 63; therefore, the probability that a student will complete one or the other degree is

An airport concourse offers a WiFi connection for \5$ plus \2$ for every 15 minutes.
If y represents the total cost and x represents the number of 15-minute intervals, which of the following linear equations best describes the given situation?

y = 7x + 5

y = 7x + 5

y = 7x + 5

y = 7x + 5

The 5 is a fixed cost that does not include the number of 15$-minute intervals. The 2$ is applied for each 15-minute interval; therefore, it is multiplied by the value of x.

Which of the following expressions is equivalent to (x + 12)(-7 + 9x)?

9x2 +115x-84

9x2 +115x-84

9x2 +115x-84

9x2 +115x-84

Using FOIL you obtain 9x2 +115x + 84.

The area of a parallelogram is 72 square meters.
If the base has a length of 9 meters, what is its height?

3$ meters

3$ meters

3$ meters

3$ meters

The area of this parallelogram is A = bh where b = 9 and A = 72. Using these values, 72 = 9h and h = 8.

The following table shows values of a function g(x) for selected values of x:

x012

g(x)
81012


If g(x) and each of the functions below were graphed, which function would represent a line with a slope that is the same as the slope of the line represented by g(x)?

m(x)=5x+60

m(x)=5x+60

m(x)=5x+60

m(x)=5x+60

The slope of g(x) is 2 while the slopes of the given answer options are represented by the coefficients of x.

To the nearest tenth of a centimeter, what is the height of a cylinder with a volume of 2 cubic centimeters and a radius of 0.3 centimeters?

0.6

0.6

0.6

0.6

Using the formula V = pi r2 h with given values for volume and height yields 2= pi(0.3)2 h, which is equivalent to .

A sauce recipe requires 2x1/2 cups of vegetable stock for every 1/2 cup of soy sauce used. A restaurant prepares 24 cups of this sauce recipe.
How many cups of soy sauce were used?

4$ cups

4$ cups

4$ cups

4$ cups

The ratio of stock to soy sauce is 5:1 because . Therefore, if x is the amount of soy sauce used, 5x + x = 24, or 6x = 24, and x = 4.

An investment fund requires that the amount invested in stocks S and the amount invested in bonds B must follow the following inequality:
[S\le 3B]
Use this information to complete the statement below. Choose the letter of the option that correctly completes the sentence.
The amount of money invested in stocks must ________ three times the amount of money invested in bonds.

be at least

be at least

be at least

be at least

The amount of money invested in stocks must not exceed three times the amount of money invested in bonds. The inequality indicates that the amount in stocks must be smaller than or equal to the amount in bonds. This can be expressed with the given statement.
