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 1

Answer:

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

Answer 2

Answer: The answer I believe would be C.

The answer is
D. 5040

The value of ₇P₇ or P(7, 7) is 5040 after using the permutation formula option (D) 5040 is correct.

What are permutation and combination?

A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.

We have:

= ₇P₇

Here P represents the permutation:

We can calculate the value of ₇P₇ using the formula:

P(n, r) = n!/(n - r)!

n = 7

r = 7

Plug the above values in the formula:

₇P₇= P(7, 7) = 7!/(7 - 7)!

₇P₇ = 7!/(0)!

₇P₇ = 7!

₇P₇ = 7×6×5×4×3×2×1

The above represents a mathematical operation, Now multiply all the numbers.

₇P₇ = 5040

Thus, the value of ₇P₇ or P(7, 7) is 5040 after using the permutation formula option (D) 5040 is correct.

I will give BrainleistSelect the choice that translates the following verbal phrase correctly to algebra: the product of 12 and y increased by 11
12(y + 11)
12y + 11
12 + 11y
12(11y)

Answers

Answer:

Step-by-step explanation:

The product of 12 and y is 12y.

If we increase this product by 11, we get

12y + 11

So the second answer choice is the correct one.

Answer:

Step-by-step explanation:12y+11
