All students at Hammon Middle School filled out a questionnaire for the cafeteria. One question asked about ice cream flavor preferences.
45% of the students at Hammon Middle School like chocolate ice cream best.
30% of the students at Hammon Middle School like cookies and cream ice cream best.
25% of the students at Hammon Middle School like vanilla ice cream best
In Coach Reyes' 7th period PE class at Hammon Middle School, there are 40 students.
Create a bar graph to show the number of students in Coach Reyes' 7th period PE class who MOST LIKELY like chocolate ice cream best, like cookies and cream ice cream best, and like vanilla ice cream best.
Based on the percentages given, we can estimate that in Coach Reyes' 7th period PE class:
- 18 students like chocolate ice cream best (45% of 40 students)
- 12 students like cookies and cream ice cream best (30% of 40 students)
- 10 students like vanilla ice cream best (25% of 40 students)
Here is the bar graph representation:
Number of Students by Ice Cream Flavor Preference:
18 students: Chocolate
12 students: Cookies and Cream
10 students: Vanilla

Laith and Khalen are partners in a game. Laith's score (L) and Khalen's score (K) at halftime are shown on the number line.
Their team score recorded at halftime is 4. What could this score represent?
Responses
A the difference between Laith's score and Khalen's scorethe difference between Laith's score and Khalen's score
B the absolute value of the difference between Laith's score and Khalen's scorethe absolute value of the difference between Laith's score and Khalen's score
C the sum of the absolute value of Laith's score and the the absolute value of Khalen's scorethe sum of the absolute value of Laith's score and the the absolute value of Khalen's score
D the sum of Laith's score and Khalen's scorethe sum of Laith's score and Khalen's score
A. the difference between Laith's score and Khalen's score
The team score of 4 at halftime would represent the difference between Laith's score and Khalen's score. This is because the team score is usually the result of combining the individual scores of the players, so the team score of 4 could represent how many points one player is leading by over the other.
Luis owes the school cafeteria $10, which means that he has a –$10 balance on his lunch account.
Which situation illustrates the idea of a number and its opposite?
Responses
A Luis' mom deposits $50 in Luis' lunch account, so Luis has a $40 balance on his lunch account.Luis' mom deposits $50 in Luis' lunch account, so Luis has a $40 balance on his lunch account.
B Luis spends $4 more dollars on lunch without depositing money into his lunch account. Luis spends $4 more dollars on lunch without depositing money into his lunch account.
C Luis' mom deposits $10 in Luis' lunch account, so Luis has a $0 balance on his lunch account.Luis' mom deposits $10 in Luis' lunch account, so Luis has a $0 balance on his lunch account.
D Luis skips lunch because he does not want to go further into debt.
C. Luis' mom deposits $10 in Luis' lunch account, so Luis has a $0 balance on his lunch account.
In this situation, Luis originally had a debt of -$10, then his mom deposited $10, changing his balance to $0. This illustrates the concept of a number and its opposite, where the deposit of $10 balanced out his previous debt of -$10.
Spencer is using a cube numbered 1 to 6 to conduct probability experiments. In the first experiment, he rolls the number cube 250 times. The number 1 is rolled 47 times.
Which value is the closest estimate of the experimental probability of rolling a 1?
To find the experimental probability of rolling a 1, you divide the number of times a 1 was rolled by the total number of rolls:
Experimental probability of rolling a 1 = Number of times 1 was rolled / Total number of rolls
Experimental probability of rolling a 1 = 47 / 250
Experimental probability of rolling a 1 = 0.188
Therefore, the closest estimate of the experimental probability of rolling a 1 is approximately 0.188.
In the second experiment, Spencer rolls the number cube 350 times.
Select the TWO values that represent an approximate frequency of rolling a 2 in 350 attempts.
To find the approximate frequency of rolling a 2 in 350 attempts, we need to find the expected number of times a 2 would be rolled based on the probability of rolling a 2 on a fair, six-sided number cube.
Since the cube is fair, each number (1 to 6) has an equal probability of 1/6.
Expected frequency of rolling a 2 in 350 attempts:
(1/6) * 350 = 350 / 6 ≈ 58.33
The two values that represent an approximate frequency of rolling a 2 in 350 attempts are:
- 58
- 59
Shana recently led efforts to clean up the city park for the kids and efforts to provide home and yard repair or cleaning for individuals who needed assistance.
Of the 80 volunteers who showed up to help with the city park clean-up one Saturday, 60% returned a second Saturday to help with the community outreach service day to the elderly or disabled.
After this second Saturday, 6 of the volunteers signed up to continue helping with the community outreach service day once a month.
What percentage of the volunteers from the second Saturday signed up to continue helping with community outreach service day once a month?
