For 12, the answer would be Y is greater than or equal to 8. If you subtract 193 from both sides of the inequality, you are left with y and 201-193=8. So the overall inequality would look like y>=8. Therefore, you would shade from 8, and everything greater than 8, with a closed circle.

Which value of a would make the following expression completely factored? X^

ololo11 [35]

Answer:

A. 12

Step-by-step explanation:

Selecting B, C, or D would create a difference of perfect squares since each of these numbers are perfect squares. Additional factoring would then be needed.

$x^2-36 = (x+6)(x-6)\\x^2-49 = (x+7)(x-7)\\x^2-81=(x+9)(x-9)$

But selecting 12 gives $x^2-12$ which cannot be factored. It is factored completely.

natka813 [3]

Okay so think of it like this, You have the numbers 1,5,8,9,15. So you have the first "Whisker" and that stands for the lower observation which is 1. Then you have the first part of the box which is the firsrt quartile 5. The you have the middle of the box which is the median easy way to remember that is meddle middle, And the median is 8. Then you have your third quartile which 9. Then you have your greatest quartile, 15. And that is your box and whisker plot. Hope this helped!

zzz [600]

Answer:

Options a, b, c are correct.

Step-by-step explanation:

First let's see the equation that governs the statement, which is the following:

$r = \frac{cov (x, y)}{\sqrt{var(x) var (y)} }$

Therefore, reading options a, b, c are correct.

Since from the formula we have the correlation coefficient of two variables x and y and here it shows us the correlation between x, y and y, x is the same.

This means that the 0.4 correlation implies a moderate but positive relationship between the two variables.

that is, the highest or lowest value of one variable implies a highest or lowest value of the other variable, respectively.
