Alexander found the means-to-MAD ratio of two data sets to be 2.1.What can he conclude about the distributions?

A.
They are similar.

B.
They are somewhat similar.

C.
They are different.

D.
They are identical.

Answers

Answer 1
Answer: Okay, So We Need To First Remember The Rule About Means-To-Mad Ratios. It Is :
"You can use the means-to-MAD ratio to describe the similarity of two distributions. Divide the positive difference in the means by the larger of the two MAD values. If this ratio is 1 or less, the two distributions are similar. If this ratio is between 1 and 2.5, the two distributions are somewhat similar. If this ratio is greater than 2.5, the two distributions are different. "
So, Lets Use This Info. 2.1 Is Greater Than 1, So They Are Not Similar. It Is Greater Than 1 But Less Than 2.5, So, They Are Somewhat Similar. 2.1 Is Less Than 2.5, So They Are Not Different. They Cant Be Identical, Because That Would Mean It Is 0.  So, This Means That The Answer Is They Are Somewhat Similar. I Hope This Helps!

a sum of RS 500 is in the form of denominators of RS5 & RS 10..if the total no. of notes is 90 ,find the no. of notes of each type................                                                                              do it by process will be mark as best

Answers

let rs.5 denominations be x , then rs 10 denominations will be 90-x

then total amount 5x + 10(90-x) which is rs.500

 5x + 10(90-x) = 500

900 - 5x = 500
400 = 5x
therefore x = 80
          therefore no. of rs.5 is 80
no. of rs.10 is 90-x = 90-80 = 10
