Mallory is on a budget and wants to determine which cereal is a better buy. A 10-ounce box of Cereal A costs $2.70 and a 13-ounce box of Cereal B costs $3.64. The store is selling each cereal in 15 ounce boxes. Which cereal is cheaper and by how much?
Answer:
Cereal A is cheaper by $0.15
Step-by-step explanation:
Cost of a 10-ounce box of Cereal A = $2.70
So,
Cost of a 1-ounce box of Cereal A = [tex]\frac{2.70}{10}=\$0.27[/tex]
Cost of a 15-ounce box of Cereal A = [tex]0.27(15)=\$4.05[/tex]
Also,
Cost of a 13-ounce box of Cereal B = $3.64
So,
Cost of a 1-ounce box of Cereal B = [tex]\frac{3.64}{13}=\$0.28[/tex]
Cost of a 15-ounce box of Cereal B = [tex]=0.28(15)=\$4.2[/tex]
Here,
Cost of a 15-ounce box of Cereal B - Cost of a 15-ounce box of Cereal A = [tex]4.2-4.05=\$0.15[/tex]
Therefore,
Cereal A is cheaper by $0.15
Education researchers are interested in the workload expectations of freshmen at a local university. Since all of the freshmen are randomly placed into freshman seminar classes, the researchers randomly select 3 freshman seminar classes and survey all of the students within those classes. Which sampling method was used?
cluster sampling
simple random sampling
stratified random sampling
systematic random sampling
Answer: Cluster Sampling
Step-by-step explanation: I just took this test and got it correct :)
If the researchers choose three freshmen seminar classes at random and poll every pupil in those classes. The Cluster Sampling method was applied. Option A is correct.
What is cluster sampling?In the probability sampling technique known as cluster sampling, you split a population into groups, such as districts or schools, and then randomly choose a sample from among these groups. Ideally, each cluster should be a small representation of the population as a whole.
When studying large, dispersed populations, cluster sampling is most effective since interviewing every individual would be expensive, time-consuming, and sometimes impossible.
By using cluster sampling, it is possible to create smaller, more comparable clusters that represent the population being studied.
Thus, the researchers choose three freshmen seminar classes at random and polled every pupil in those classes. The Cluster Sampling method was applied. Option A is correct.

Answer:
6. 75 Students in Mrs.Reynolds class.
7. 60 Birthdays in February
8. February and May are a combined 20% of birthdays
9. March has 24% of the students birthdays
Step-by-step explanation:
6. Adding all the numbers will give us 75 total students.
7. 450 divided by 7 will get us 6. And there are 10 birthdays in February, so we do 10 times 6 and get 60.
8. On a calculator if you input 20% of 75 you will get 15. February and May are the only 2 birthday months that if you add them up you get 15.
9. If you put 24% of 75 on a calculator you will get 18. March is the only month with 18 birthdays.
There is Mrs. Reynolds' class has 75 students. February has 60 birthdays. February and May account for 20% of all birthdays. In March, 24% of students celebrate their birthdays.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
Mrs. Reynolds creates a graph of the number of students who have birthdays in the first half of the year.
The graph has been given in the question.
Here y-axis represents Months and the x-axis represents the Number of students
As per the given graph, the required solution would be as:
Adding all of the numbers together generates a total of 75 students.
450 divided by 7 equals 6. And there are ten birthdays in February, so multiply 10 by 6 to get 60.
If you enter 20% of 75 into a calculator, you will obtain 15. February and May are the only two birthday months that total up to 15.
If you multiply 24% of 75 by 18, you get 18. March is the only month in which there are 18 birthdays.
Thus, there is Mrs. Reynolds' class has 75 students. February has 60 birthdays. February and May account for 20% of all birthdays. In March, 24% of students celebrate their birthdays.

Maya and Reginald are installing hardwood flooring. Maya can install flooring in a room in 4 hours. Reginald can install flooring in a room in 3 hours. How long would it take them if they worked together?
Answer:
1 hour 42 minutes approx
Step-by-step explanation:
Given data
Mayas work rate= 1/4 room per hour
Reginald work rate= 1/3 room per hour
Let the total time taken for both of them be T
Hence their combined work rate
1/4+1/3= 1/T
3+4/12=1/T
7/12=1/T
T= 12/7
T= 1.7 hours
Hence it will take them 1 hour 42 minutes approx
