Alexander found the means-to-MAD ratio of two data sets to be 3.4.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:

They are different.

Step-by-step explanation:

Given that Alexander found the means-to-MAD ratio of two data sets to be 3.4.

Data set I has mean / mean absolute deviation as 3.4 times the data set II.

That is why the ratio = 3.4

This implies that the two data sets have different variations, and as a result different entries

They cannot be identical because ratio is not 1.

They cannot be similar as mad is higher for I data set

The only conclusion is option

C) they are different

The answer I believe would be C.

Solve the systems of equations 3x-4y=-2 and -x+8y=-23

Answers

We can use the subtraction method in order to solve for this system. First, line up the equations:

3x - 4y = -2
x + 8y = -23
_________
Our goal is to essentially get rid of one of the variables. We can do so by multiplying the first equation by 2:

6x - 8y = -4
x + 8y = -23
__________
7x = -27

x = -27/7

Input x into one of the equations to solve for y:
-27/7 + 8y = -23
-27 + 56y = -161
56y = -134
y = -134/56
y = -67/28

(-27/7, -67/28)

Write 54+63 as the product of the gcf of 54 and 63 and another sum

Answers

1) what is 54+63? it's 117!

2) what is their gcf? well, they''re both divisible by 9:

54=9*6
63=9*7

and 6 and 7 have no divisors in common other than 1, so gcf is actually 9!

so what is 117 as a sum of 9 and something else?

the something else s 117-9=108

so the answer is 9+108
