What is the means-to-MAD ratio of the two data sets, expressed as a decimal?Data set Mean Mean absolute deviation (MAD)
1 10.7 2.4
2 13.7 2.5

Answers

Answer 1

Answer: The correct answer for the question that is being presented above is this one:

To find the mean of a set, add up all of the numbers and divide by how many numbers you have. For the first set:
u = (10.7+2.4)/2 = 6.55
For the second set:
u = (13.7 + 2.5)/2 = 8.1

To find the mean absolute deviation, (MAD) find the mean of the distances of each number from the mean.
First set:
MAD = (|10.7-6.55| + |2.4-6.55|)/2 = 4.15
Second set:
MAD = (|13.7-8.1| + |2.5-8.1|)/2 = 5.6

The means-to-MAD ratio is simply that, divide one by the other and that's it.
For the first set:
6.55 / 4.15 = 1.57831325
For the second set:
8.1 / 5.6 = 1.44642857

A class of 25 students had a vote. 24% voted on selection 'a'. 1/5 of the class voted on selection 'b'. And 0.56 voted on selection 'c'. How many of the students voted on selection 'c'?

Answers

To find this out, change all of them into decimals. To change a percent into a decimal, divide the percent by 100. To change a fraction into a decimal, divide the numerator by the denominator. 24% as a decimal is 0.24. 1/5 as a decimal is 0.20.

Multiply each of the decimals by the number of students.

So,

0.24*25= 6

0.20*25= 5

0.56*25= 14

6 people voted on section A

5 people voted on section B

14 people voted on section C

Hope it helps :)

Find 0.56 of 25.

0.56 * 25 = 14

So 14 of the students voted on selection 'c'.

Can you tell me this two? Thanks
