Answer:

Any number above 85.6

Step-by-step explanation:

To calculate the mean you add all of the scores together then divide by how many scores you added

So in this case you would add 84 + 72 + 90 + 87 + 95 = 428

Then you would Divide 428 by five because you are adding 5 numbers

428/5 = 85.6

It says the score increased so as long as then score is greater than 85.6 it is an option.

Answer:

D. A\subset \mathbb{R}\times\mathbb{R}.

Step-by-step explanation:

Consider the set

A=\left\{(2,3),\ (5,1),\ (-3,-2),\ (0,3)\right\}

This set consists of four ordered pairs.

The first numbers in these pairs are 2,\ 5,\ -3,\ 0. These numbers are integer numbers (not natural, because -3 is negative).

The second numbers in these pairs are 3,\ 1,\ -2,\ 3. These numbers are integer numbers too (not natural, because -2 is negative).

Options contain only natural and real sets, so, the first and the second numbers are real numbers and

A\subset \mathbb{R}\times\mathbb{R}.
