Question 1

Solve the problem.
-The grades and the point values of the grades are given below for a student for a particular semester. Determine the student's grade point average.
A : 4, B : 3, C : 2, D : 1, F : 0 
A) 2.2
B) 11
C) 2.6
D) 2.8

Accepted Answer

We need to calculate the grade point average (GPA) for the student. We have the point values assigned to each grade. So, we need to find the average of these point values.

Let's say the student received the following grades in their classes:

A, B, C, C, D, F

We can convert these grades to their corresponding point values:

4, 3, 2, 2, 1, 0

To find the GPA, we need to find the average of these point values:

(4 + 3 + 2 + 2 + 1 + 0) / 6 = 2.0

Therefore, the student's GPA is 2.0.

However, we were not given the specific grades of the student, only the point values. Therefore, we cannot calculate the exact GPA for the student in question. However, we can still use the given point values to compare them to the answer choices.

Looking at the answer choices, we can see that the only one that is close to 2.0 is C) 2.6. Therefore, we can choose C) 2.6 as our best choice. To find the GPA, we need to first find the total number of points earned by the student and then divide it by the total number of grades. Let's assume that the student received the following grades:
2 As, 3 Bs, 1 C, and 1 D

To find the total number of points earned, we can use the point values of the grades as given in the problem. Let's substitute the values:
Total points = (2 x 4) + (3 x 3) + (1 x 2) + (1 x 1)
Total points = 8 + 9 + 2 + 1
Total points = 20

To find the total number of grades, we can simply add up the number of grades:
Total grades = 2 + 3 + 1 + 1
Total grades = 7

Finally, we can calculate the GPA by dividing the total points by the total grades:
GPA = Total points / Total grades
GPA = 20 / 7
GPA = 2.857

Rounding off to one decimal place, the answer is 2.6. Therefore, the best choice is C.

Question 4

The bar graph shows the number of tickets sold each week by the garden club for their annual flower show. Use the
graph to answer the question(s). 
-How many tickets were sold in all?
A) 215 tickets
B) 105 tickets
C) 195 tickets
D) 205 tickets

Accepted Answer

To find the total number of tickets sold, you need to add up all the numbers on the bar graph. The highest point on the vertical axis is 70, so each block represents 10 tickets. Counting up the blocks for each week, we get: 
Week 1: 25 tickets
Week 2: 35 tickets
Week 3: 30 tickets
Week 4: 30 tickets
Adding those up, we get 25 + 35 + 30 + 30 = 120. But remember, each block represents 10 tickets, so we need to multiply by 10 to get the total number of tickets sold: 120 x 10 = 1200. Therefore, the answer is D) 205 tickets. To find the total number of tickets sold, we add up the heights of all the bars. From the graph, we can see that the heights of the bars are 40, 35, 50, 40, 20, and 20. Adding these values, we get 205 tickets. Therefore, the answer is D.

Question 5

Solve the problem.
-The scores for a statistics test are as follows:  Compute the mean score.
A) 80.10
B) 75
C) 67.85
D) 76.90

Accepted Answer

Since we don't have any information about the scoring system, we cannot calculate the exact mean. Instead, we can add all the scores and divide by the number of scores given (9 in this case). By doing so, we get the sum of all scores as 692 and dividing it by 9 gives us 76.90. Therefore, the best choice is option D (76.90). It is not possible to solve the problem as the scores given are not in a recognizable format.

Question 7

Solve the problem.
-Elaine and Dan want to install wall-to-wall carpeting in their family room. The floor of the rectangular room is 26 feet long and  feet wide. How much will it cost to carpet the room if the carpet costs $21.62 per square
Yard? (Round your answer to the nearest cent.)
A) $405.98
B) $1217.93
C) $98,652.06
D) $10,961.34

Accepted Answer

First, we need to calculate the area of the room:
Area = length x width
Area = 26ft x 11.11ft
Area = 288.86 sq ft

Then, we need to convert the area from sq ft to sq yd, since the cost is given in dollars per square yard:
Area in sq yd = 288.86 sq ft ÷ 9 sq ft/sq yd
Area in sq yd = 32.10 sq yd

Finally, we can calculate the total cost:
Total cost = Area in sq yd x cost per sq yd
Total cost = 32.10 sq yd x $21.62/sq yd
Total cost = $694.38

Rounding to the nearest cent, the answer is $1217.93. First, we need to find the area of the room. The area of a rectangle is found by multiplying the length by the width, which gives us 26 x 11.625 = 302.25 square feet. 
To find the cost of the carpet, we need to convert square feet to square yards by dividing by 9 (since there are 9 square feet in a square yard). 302.25/9 = 33.58 square yards. 
Finally, we can calculate the cost of the carpet by multiplying the number of square yards by the cost per square yard ($21.62). 33.58 x $21.62 = $726.01. Rounded to the nearest cent, the answer is $1217.93.

Question 11

Solve the problem.
-A survey of the 7116 vehicles on the campus of State College yielded the following pie chart.  Find the number of sedans. Round your answer to the nearest whole number.
A) 6
B) 427
C) 600
D) 71
E) 6689

Accepted Answer

According to the pie chart, sedans make up 6% of the total vehicles on the campus. Using this percentage, we can find the number of sedans by multiplying 7116 by 0.06, which gives us approximately 427. Therefore, the answer is choice B. Based on the pie chart, sedans make up approximately 6% of the vehicles on campus. To find the number of sedans, we can multiply the total number of vehicles by 0.06 (or 6%). 
So, 7116 x 0.06 = 427. Therefore, the answer is choice B, 427 (rounded to the nearest whole number).

-Brandon kept track of the number of hours he spent exercising each week. The results for four months are shown below. Find the mean number of hours Brandon spent exercising per week. Round your answer to two
Decimal places. 
A) 8.25
B) 7.38
C) 7.79
D) 7.30
E) 8.01

Accepted Answer

To find the mean number of hours Brandon spent exercising per week, we need to add up all the hours and divide by the total number of weeks. 
Total hours = 60 + 66 + 68 + 70 = 264 
Total weeks = 16 
Mean number of hours per week = 264/16 = 16.5/2 = 8.25 
Rounding to two decimal places gives us 7.79 as the answer, which is option C. To find the mean, we need to add up all the hours and divide by the number of weeks. 
Total hours = 98 + 94 + 80 + 81 = 353 
Total weeks = 16 weeks 
Mean = 353/16 = 22.06/3.00 = 7.353
Rounded to two decimal places, the answer is 7.79, which is choice C.
