If 19 out of 110 people say volleyball is their favorite sport, how many people could be expected to choose volleyball out of 330 people?
Blank Space__________people
Type the correct answer.
To find out how many people could be expected to choose volleyball out of 330 people, we can set up a proportion:
19/110 = x/330
To solve for x, we can cross-multiply and then divide:
110x = 19 * 330
110x = 6270
x = 6270/110
x = 57
Therefore, the correct answer is 57 people.
Change this percent to a fraction.
64%
Select the correct answer.
Question 4 options:
16 over 25
fraction numerator 4 over denominator 5 end fraction
fraction numerator 8 over denominator 25 end fraction
fraction numerator 2 over denominator 3 end fraction
To change a percent to a fraction, we divide the percent by 100 and simplify if possible.
For 64%, we have:
64% = 64/100
To simplify this fraction, we divide both the numerator and denominator by their greatest common divisor (GCD), which is 4:
64/100 = (64/4)/(100/4) = 16/25
Therefore, the correct answer is fraction numerator 16 over denominator 25

Solve this problem.
Of 3,000 pet owners surveyed, 9% purchased their pets from a pet store. How many pets were purchased from a pet store?
Blank Space__________pets
To find out how many pets were purchased from a pet store, we can set up a proportion:
(9/100) = x/3000
To solve for x, we can cross-multiply and then divide:
100x = 9 * 3000
100x = 27000
x = 27000/100
x = 270
Therefore, the correct answer is 270 pets.
Question 6 options:
Solve this problem.
Forty people were asked their favorite kind of pizza. Thirty percent of the people surveyed chose sausage. How many people preferred sausage?
Blank Space__________people
To find out how many people preferred sausage, we can set up a proportion:
30% = x/40
To solve for x, we can cross-multiply and then divide:
100x = 30 * 40
100x = 1200
x = 1200/100
x = 12
Therefore, the correct answer is 12 people.

Eight cards with one letter on each card spell out the word SURPRISE. If you choose one card at random, what is the probability of choosing a "P"?
To find the probability of choosing a specific card, in this case, the letter "P," we need to determine the total number of possible outcomes and the number of favorable outcomes.
Total number of possible outcomes: There are 8 cards in total.
Number of favorable outcomes: There is only 1 card with the letter "P".
Therefore, the probability of choosing a "P" is 1 out of 8, which can be written as a fraction as 1/8.

To find the probability of choosing one card at random, we need to determine the total number of possible outcomes and the number of favorable outcomes.
Total number of possible outcomes: There are 8 cards in total.
Number of favorable outcomes: Since we are choosing one card at random, any of the 8 cards could be selected.
Therefore, the probability of selecting any card is 8 out of 8 or simply 1. This can be written as P(E) = 1.

Katie earns money by selling lemonade. She keeps track of how much she spends and makes each weekend. The following are her profits and expenses: -$3, +$4, -$3, +$6, -$2, +$5, -$6, +$12. Which statement is true?
Select the correct answer.
Question 10 options:
She made $6.
She lost $11.
She made $13
She lost $13.
To determine whether Katie made a profit or incurred a loss, we sum up all her profits and expenses:
Profits: +$4, +$6, +$5, +$12 = +$27
Expenses: -$3, -$3, -$2, -$6 = -$14
To calculate the overall profit or loss, we subtract the total expenses from the total profits:
Profit/Loss = Total Profits - Total Expenses
Profit/Loss = $27 - (-$14)
Profit/Loss = $27 + $14
Profit/Loss = $41
The statement "She made $41" is not listed among the options. None of the provided options accurately reflects her overall profit or loss.

The average temperature on the surface of the earth is 15 degrees. On the surface of Mars, the average temperature is -50 degrees. What is the difference in these two temperatures?
Blank Space__________degrees
To find the difference in temperature between the average temperature on Earth (15 degrees) and the average temperature on Mars (-50 degrees), we subtract the lower temperature from the higher temperature:
15 degrees - (-50 degrees)
To subtract a negative number, we can change it to addition:
15 degrees + 50 degrees
This gives us:
65 degrees
Therefore, the difference in temperature between Earth and Mars is 65 degrees.
Question 12 options:
Find the sum.
+5 + (-2)
Type the correct answer.
To find the sum of +5 and -2, we simply add them together:
+5 + (-2) = 5 - 2 = 3
Therefore, the correct answer is 3.
