Step-by-step explanation:

You don't have to use Rick Astley, but you can if you want ;)

Aswer: 4.5 ft^2

Answer is below. Look at the explanation to understand my answer.

To multiply fraction, you'll need to multiply the numerator by the other numerator and the denominator by the other denominator. You don't need to make the denominators common.

Normally you'll multiply the numerator and the denominator, but for this, 12 is a whole number. To convert it into a fraction, put 1 as the denominator.

12 will now be ¹²⁄₁.

Remember, you don't need to make common denominators. Only for subtracting and adding fraction with unlike denominators.

Our problem will be like this: [tex]\frac{12\times3}{1\times8}[/tex]

With that being said, let's solve.

12 times 3 equals 36.

1 times 8 equals 8.

Our answer is ³⁶⁄₈, but it is improper. We will need to convert it into a mixed number by dividing the numerator by the denominator.

Find the Greatest Common Factor (GCF) of 36 and 8. If there is, reduce the fraction dividing both numerator and denominator by it.

Therefore, the GCF is 4.

Whatever you do to the top, You do to the bottom.

Our problem will be this: [tex]\frac{36\div4}{8\div4}[/tex]

36 divided by 4 is 9.

8 divided by 4 is 2.

Hence the fraction is ⁹⁄₂, but the fraction is still improper. Instead of finding the GCF, we will use long division.

We will divide 9 by 2 to get the answer.

9 divided by 2 is 4 with a reminder of 1.

The reminder will be the numerator, the denominator will be the same, and the quotient, or the answer will be the mixed number.

Therefore, our final answer is 4 ½.

Let me know of questions and concerns about my answer.

A teacher surveyed her class after they had taken a vocabulary test. Eighteen of the students claimed they had studied at least one hour for the test. The remaining twelve students admitted that they had not studied for the test at all. The test results (expressed as a percent) for the two groups are shown below.

Studied: 87, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 83
Did Not Study: 82, 72, 45, 91, 58, 83, 65, 87, 90, 77, 73, 89

Part 1: Calculate the mean of the group that did not study, rounded to the nearest tenth.
Part 2: Calculate the mean absolute deviation of the group that did not study, rounded to the nearest tenth.
Part 3: How many of the scores (from the group that did not study) are more than two mean absolute deviations from the mean?

Answers

Answer:

Didn't study: 76%

Mean absolute deviation: 11.2

Step-by-step explanation:

To find the mean, add all the scores from the people who didn't study and divide them by 12 (the total number of students who didn't study). You will get 76%To find the MAD, use the formula for MADTo answer the third, line them up in order. 45, 58, 65, 72, 73, 77, 82, 83, 87, 89, 90, 91. MAD is the average difference between the numbers. So, to find this answer, subtract two of the MAD's from the mean of 76%. 76-22.4 = 53.6. So, only one is more than two MAD's away from the mean of 76%.
92.5 is the answer for part 1
