Question 5 |

**The probability that the Blue Comets score the first goal in any game is 90%. What is the probability of the Blue Comets scoring the first goal in 4 straight games?**

0.81 | |

0.45 | |

0.729 | |

0.656 |

Question 5 Explanation:

The correct answer is (D). First recognize that the probability of the Blue Comets scoring the first goal in any single game is 90% regardless of whether they score first in any other game. This indicates that scoring first in consecutive games is a series of independent events. To find the probability of consecutive independent events occurring, calculate the product of their probabilities.

The probability of the team scoring first in 4 straight games is then:

0.9 * 0.9 * 0.9 * 0.9 = 0.6561, which rounds to 0.656.

The probability of the team scoring first in 4 straight games is then:

0.9 * 0.9 * 0.9 * 0.9 = 0.6561, which rounds to 0.656.

Question 6 Explanation:

The correct answer is (B). This is a function problem. A function relates an input to an output. To find ƒ(2.5), substitute 2.5 for every

ƒ(2.5) = 2(2.5)

ƒ(2.5) = 2(6.25) − 7.5 + 7

ƒ(2.5) = 12.5 − 7.5 + 7

ƒ(2.5) = 12

*x*in the original function and evaluate the expression:ƒ(2.5) = 2(2.5)

^{2}− 3(2.5) +7ƒ(2.5) = 2(6.25) − 7.5 + 7

**How many different passcodes can be formed from the letters {A, B, C, D} if each letter can only be used once?**

6 | |

24 | |

120 | |

720 |

Question 8 Explanation:

The correct answer is (B). Given that each letter can only be used once, and there are a total of 4 letters, the first character of the passcode can only be occupied by 4 different letters. After using the first letter, there are 3 letters remaining that can occupy the second spot; then 2 letters for the third spot, and only 1 letter for the last spot. The product of these values yields the total number of possibilities:

4 * 3 * 2 * 1 = 24.

The solution can also be found using the formula for the total number of different arrangements of n distinct elements:

n! = n(n − 1)(n − 2)… * 1

4! = 4 * 3 * 2 * 1

4! = 24

4 * 3 * 2 * 1 = 24.

The solution can also be found using the formula for the total number of different arrangements of n distinct elements:

n! = n(n − 1)(n − 2)… * 1

4! = 4 * 3 * 2 * 1

4! = 24

Question 9 |

**The population density of an area can be computed by dividing the total population by the total land area. The population density of Rhode Island is 870.5 people/square mile and the population is 1,055,046. What is the area of Rhode Island?**

8.25 mi^{2} | |

825 mi^{2} | |

1,212 mi^{2} | |

918 mi^{2} |

Question 9 Explanation:

The correct answer is (C).Use the definition provided in the first sentence of the question to set up an equation relating population density to area. Substitute the given values to then solve for the unknown area:

Isolate the unknown total area by multiplying both sides by the unknown area and dividing both sides by the population density (870.5):

Notice that the units of people cancel in the numerator and denominator, and that the computed area is in the expected units of square miles. This method of dimensional analysis is incredibly useful in validating a mathematical set up. The unknown area is then:

1,055,046 ÷ 870.5 = 1,212 square miles.

Isolate the unknown total area by multiplying both sides by the unknown area and dividing both sides by the population density (870.5):

Notice that the units of people cancel in the numerator and denominator, and that the computed area is in the expected units of square miles. This method of dimensional analysis is incredibly useful in validating a mathematical set up. The unknown area is then:

1,055,046 ÷ 870.5 = 1,212 square miles.

*x*^{2}+ 8*x*+ 15 = 0−5 | |

−3 | |

−2 | |

2 | |

3 | |

5 |

Question 10 Explanation:

The correct answers are (A) and (B). One easy way to solve a problem like this is by plugging each answer choice into the equation to see which values yield a true statement. Alternatively, the values can be calculated by factoring the expression:

In order to factor the quadratic, we need to find two factors of 15 (the constant term) that sum up to 8 (the coefficient of

15 = 3 * 5

8 = 3 + 5

So 3 and 5 are the two factors that meet our requirement.

The fully factored form of the quadratic is:

(

Recall that if

In this case, (x + 3)(x + 5) = 0

So either

That is, either

The roots of the quadratic are −3, and −5

In order to factor the quadratic, we need to find two factors of 15 (the constant term) that sum up to 8 (the coefficient of

*x*):15 = 3 * 5

8 = 3 + 5

So 3 and 5 are the two factors that meet our requirement.

The fully factored form of the quadratic is:

(

*x*+ 3)(*x*+ 5) = 0Recall that if

*ab*= 0, then either*a*= 0, or*b*= 0.In this case, (x + 3)(x + 5) = 0

So either

*x*+ 3 = 0, or*x*+ 5 = 0That is, either

*x*= −3, or*x*= −5The roots of the quadratic are −3, and −5

Question 11 |

Undefined | |

−2 | |

2 | |

4 |

Question 11 Explanation:

The correct answer is (B). This problem asks for the cube root of −8. The cube root of a number is the value that, when cubed (multiplied with itself 3 times), gives the number inside of the radical. Remember that a negative number raised to an even exponent gives a positive result, but when raised to an odd exponent gives a negative result. Consequently, the cube root of −8 will be a negative number. It should also be apparent that squaring 3 gives a value greater than 8, so cubing 3 would give a value much larger than 8. Trying −2 as the likely possibility:

−2 * −2 = 4 * −2 = −8. So, −2 is the cube root of −8.

−2 * −2 = 4 * −2 = −8. So, −2 is the cube root of −8.

Question 12 |

**Each player on the high school football team has been weighed, and the data are shown in the box-and-whisker plot below.**

**Based on this box-and-whisker plot, which of the following TWO statements are accurate?**

The heaviest player weighs 300 lbs. | |

One-fourth of the players weigh less than 200 lbs. | |

The median player weighs 245 lbs. | |

The lightest player weighs 200 lbs. | |

The median player weighs 225 lbs. | |

At least 2 players weigh more than 300 lbs. |

Question 12 Explanation:

The correct answers are (B) and (E). Here is the meaning of each part of the box-and-whisker plot:

In this example, the minimum value represents the lightest player on the team and the maximum value represents the heaviest player on the team. The median value is the player who is at the midpoint of the distribution. The quartile values divide the distribution into fourths.

Since the lower quartile is at 200, it is accurate to say that one-fourth of the players weigh less than 200 lbs. It is also clear from the plot that the median weight is approximately 225 lbs.

In this example, the minimum value represents the lightest player on the team and the maximum value represents the heaviest player on the team. The median value is the player who is at the midpoint of the distribution. The quartile values divide the distribution into fourths.

Question 13 Explanation:

The correct answer is (D). To evaluate a base raised to a negative exponent that is in the numerator, rewrite the expression with the base and exponent in the denominator, and rewrite the negative exponent as a positive exponent. In cases where the base raised to a negative exponent is in the denominator, rewrite the base and exponent in the numerator, and switch the sign of the exponent:

*c*= 65Question 15 |

**What is the probability of selecting a male from a group of 4 males and 8 females?**

Question 15 Explanation:

The correct answer is (A). The probability of an event taking place is the ratio of the number of successful events to the total number of possible events. In this case, a successful event is randomly selecting a male from the group. The total number of possible events is the number of people in the group. The ratio is then:

Question 16 |

**Devon owns a house cleaning company and has to give price quotes to potential customers. He figures out his price by assuming a $25 base charge and then adding $8 for each bathroom and $4 for each other room. If he uses**

*P*to represent the price,*B*for bathroom, and*R*for other rooms, which of the following represents his price quote formula?P = 25 + 12(BR) | |

P = 25 + 8B + 4R | |

P = 25(4R + 8B) | |

P = (4)(8)(R + B) + 25 |

Question 16 Explanation:

The correct answer is (B). The price quote,

*P*, will be equal to the total amount of charges. It’s given that there is a $25 base charge, so we can begin by writing the price quote as*P*= $25. To this base charge of $25, $8 per each bathroom, represented by the variable*B*, is added; our price quote is now*P*= $25 + $8*B*. Lastly, $4 per each other room,*R*, is added, and the final price quote is*P*= $25 + $8*B*+ $4*R*, or*P*= 25 + 8*B*+ 4*R*.Question 17 |

**In a coordinate plane, triangle**

*ABC*has coordinates: (−2,7), (−3,6), and (4,5). If triangle*ABC*is reflected over the y-axis, what are the coordinates of the new image?(−2,−7), (−3,−6), (−4,−5) | |

(−2,−7), (−3,−6), (4,−5) | |

(2,7), (3,6), (−4,5) | |

(2,7), (3,6), (4,5) |

Question 20 Explanation:

The correct answer is (C). One way to solve this problem is to draw the figure and then count how many units each point is from the y-axis, and count that many units in the opposite direction. A more efficient method is to recognize that reflecting over the y-axis causes the x-value to switch sign and does not influence the y-value of the point.

Reflecting (−2,7), (−3,6), (4,5) across the y-axis produces the points (2,7), (3,6), (−4,5).

Reflecting (−2,7), (−3,6), (4,5) across the y-axis produces the points (2,7), (3,6), (−4,5).

Question 21 |

**Consider the list:**

**2, 2, 3, 5, 9, 11, 17, 21**

**If the number 23 is added to the list, which measurement will NOT change?**

mean | |

median | |

mode | |

range |

Question 21 Explanation:

The correct answer is (C). The mode will not change. The mode is the number that appears the most frequently; in this case it is 2. The remaining measures will change:

The mean is the average, and in this case it will increase because a number larger than the current average is added to the list.

The median is the number in the middle, and it will change from 7 to 9.

The range is the difference between the highest and lowest numbers and will change from 19 to 21 because a new maximum value is added to the list (21 − 2 = 19 and 23 − 2 = 21).

The mean is the average, and in this case it will increase because a number larger than the current average is added to the list.

The median is the number in the middle, and it will change from 7 to 9.

The range is the difference between the highest and lowest numbers and will change from 19 to 21 because a new maximum value is added to the list (21 − 2 = 19 and 23 − 2 = 21).

Question 25 |

**Which scatter plot shows weak negative correlation?**

#1 | |

#2 | |

#3 | |

#4 |

Question 25 Explanation:

The correct answer is (B). With positive correlations, as one variable increases, the other variable increases as well. This results in a scatter plot showing a positive slope. With negative correlations, as one variable increases, the other variable decreases (increasing x values result in decreasing y values). Graphs #2 and #4 show negative correlation because the y value decreases as the x value increases.

The closer the data points come to making a straight line, the higher the correlation between the two variables, or the stronger the relationship. The further the data points are from showing a straight line, the weaker the correlation. Since the data points in Graph #2 are not grouped tightly along a line, it indicates a weak correlation.

#1 Shows no correlation.

#2 Shows weak negative correlation.

#3 Shows strong positive correlation.

#4 Shows strong negative correlation.

**There are 10 red marbles, 4 blue marbles, and 7 white marbles in a jar. One marble is chosen at random and then returned to the jar, and then a second marble is chosen at random. What is the probability that both of the marbles chosen are white?**

Question 26 Explanation:

The correct answer is (B). To calculate the probability that an event occurs, divide the number of possible successful events by the total number of events. In this case, a success is selecting a white marble, and the total number of events is the total number of marbles. Because the first selected marble is returned to the jar, the second selection does not depend on the first selection. To find the probability of consecutive independent events occurring, calculate the product of their probabilities.

The probability of selecting a white marble is:

−14.5 |

Question 30 Explanation:

The correct answer is (C). The distance between points

= |−11.2 − 3.3|

= |−14.5|

= 14.5

Recall that the absolute value of a number is its distance from 0, it is always positive.

*A*and*B*on a number line is the absolute value of the difference between those two points. Distance is always a positive value. Evaluate the difference between the points and then apply the absolute value:*AB*= |*b*−*a*| or |*a*−*b*|= |−11.2 − 3.3|

Question 31 Explanation:

The correct answers are (B) and (D). The square root of a number is the value that when multiplied with itself gives the number inside the square root, for example: √16 = ±4, because 4 * 4 = 16, and −4 * −4 = 16.

Notice that answer choice (B) shows a negative value inside the square root. This answer, √−9, must be undefined, because there is no real number that when multiplied with itself will give −9. All real numbers, when squared, give a positive value.

Answer choice (D) shows division by 0, which is always undefined.

**What is the slope of the line that passes through points (0,5) and (7,0) on the coordinate plane shown below?**

Question 33 Explanation:

The correct answer is (B). The slope of a line, which can be remembered as “the rise over the run,” is the change in

Substitute the given points (0,5) and (7,0) into the equation to calculate the slope:

*y*values divided by the change in*x*values across two points on a line. Written algebraically, the slope is defined as:Substitute the given points (0,5) and (7,0) into the equation to calculate the slope:

**Which of the following equations represents**

*y*in terms of*x*for all ordered pairs listed?y = 4x ÷ 3 | |

y = 2x + 3 | |

y = x + 5 | |

y = 3x^{2} |

Question 34 Explanation:

The correct answer is (B). By inspecting the ordered pairs, it can be seen that as the

The answer must be

11 = 2(4) + 3

11 = 8 + 3

11 = 11

*x*value increases by 1, the*y*value increases by 2. This indicates a linear relationship, and the answer choice containing*x*^{2}can be eliminated. Using the definition of the slope, which is calculated as:The answer must be

*y*= 2*x*+ 3. This answer can be further verified by substituting each ordered pair into the equation, for example:11 = 2(4) + 3

11 = 8 + 3

11 = 11

**The graph provided shows the change in velocity of a rocket from time 0 to time 10. During what span of time is the rocket’s velocity decreasing?**

0 to 2 | |

0 to 4.6 | |

2 to 4.6 | |

3 to 4.6 |

Question 35 Explanation:

The correct answer is (C). The horizontal axis represents time and the vertical axis represents velocity. The rocket starts at a positive velocity, 3, and continues increasing in velocity until hour 2. At hour 2 the rocket reaches its apex and after hour 2 its velocity decreases until reaching a minimum at hour 4.6. The rocket’s velocity decreases over the hours 2 to 4.6.

**3**

^{1}+ 2^{0}− 1^{3}= ?0 | |

2 | |

3 | |

4 |

Question 36 Explanation:

The correct answer is (C). Any number raised to the power of 1 equals itself, so 3

Any number, except zero, that is raised to the 0 power equals 1, so 2

When 1 is raised to any power it always equals 1. The expression becomes:

3 + 1 − 1 = 3

^{1}is equal to 3.Any number, except zero, that is raised to the 0 power equals 1, so 2

^{0}equals 1.When 1 is raised to any power it always equals 1. The expression becomes:

3 + 1 − 1 = 3

**Carlos is planning to serve lemonade in cone-shaped paper cups at his church picnic. There will be 25 people at the picnic, but he's not sure how much lemonade he will need. As his first step to figure out how much lemonade to prepare, he decides to find the volume of liquid that one of the cone-shaped cups will hold. He measures one of the cups and finds that it has a diameter of 2.5 inches and a height of 3.625 inches. What is the volume of this cup rounded to the nearest hundredth? (use 3.14 for pi)**

5.08 in^{3} | |

5.93 in^{3} | |

18.61 in^{3} | |

23.71 in^{3} |

Question 37 Explanation:

The correct answer is (B). Use the volume formula of a cone given on the Mathematics Reference Sheet:

where

Volume = 5.93 inches cubed.

where

*r*is the radius (half the diameter) and*h*is the height. Substituting the given values:Volume = 5.93 inches cubed.

**If the two triangles shown below are similar, what is the value of**

*x*?5 in | |

12.8 in | |

18 in | |

20 in |

Question 38 Explanation:

The correct answer is (D). Problems involving similar figures can be solved using proportions. The issue with this problem is that the two triangles do not agree in measurement. First we must convert the feet measurement into inches, recall that 12 inches is 1 foot:

We can now set up our proportion. Cross multiply to solve for

8

We can now set up our proportion. Cross multiply to solve for

*x*:8

*x*= 160*x*= 20Question 39 |

**Li wants to buy as many bags of mulch as possible with his $305, and he would like them to be delivered to his house. The cost is $7.50 per bag and there is a $35.75 delivery charge. The mulch is only sold in full bags. How many bags can Li buy?**

36 | |

45 | |

46 |

Question 39 Explanation:

The correct answer is (A). From Li’s initial amount of $305, a flat $35.75 delivery charge is deducted:

$305 − $35.75 = $269.25.

We can then divide this amount by the cost per bag to find the total number of bags that Li can buy:

$269.25 ÷ $7.50 = 35.9 bags. However, the question states that the mulch can only be sold in full bags, so we must round our answer down to ensure that Li does not exceed his budget.

$305 − $35.75 = $269.25.

We can then divide this amount by the cost per bag to find the total number of bags that Li can buy:

$269.25 ÷ $7.50 = 35.9 bags. However, the question states that the mulch can only be sold in full bags, so we must round our answer down to ensure that Li does not exceed his budget.
