The cost of each friendship bracelet in dollars and cents was J $7.75

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that Abigail paid $62.00 for 8 friendship bracelets. Each bracelet cost an equal amount.

Cost of 8 friendship bracelets =  $62.00

Therefore,

Cost of 1 friendship bracelets =  $62.00/ 8

Cost of 1 friendship bracelets =  7.75

The cost of 1 friendship bracelets is $7.75

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.

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.

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

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.

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:

parallel lines do not intersect at one point.

Step-by-step explanation:

hope this helps :)

Answer:

"Parallel lines intersect at one point" is NOT true

Step-by-step explanation:

Parallel lines never touch, therefore they will never intersect.

While with the other two options, parallel lines will have the same slope because they run at the same slope equal distance from each other no matter the circumstance, that is the definition of parallel lines... sorta; and perpendicular lines will always create a right angle at their point of intersection.

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
