Someone pls help me asap ahh tysm if you do

Step-by-step explanation:

1.

So, if is asking the number that lies closest to..

We know that = about 7.07, meaning that the whole number that is closest to it is 7, because we are rounding to the nearest whole number.

Side note: is not a perfect square root because we don't get a whole number.

2.

(rounded to 3.32)

and we have the number 3.5

Now, just place these in order

3, 3.32, 3.5, 4

which is basically the same as

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

the mean and mad
