SAT math scores have a bell-shaped distribution with a mean of 515 and a standard deviation of 114.

nadezda [96]

Hey there mate :)

Analysis :

$401 = 515 - 114 = u - 6$

And

$173 = 515 - 3.114 = u - 36$

$= \frac{p(u - 36 < u < u + 36) - p(u - 6 < u < u + 6)}{2}$

$= \frac{99.73percent - 68.21percent}{2}$

$= \frac{31.46percent}{2}$

$= {15.73percent}$

Then, calculating,

$u - 26 = 515 - 2 \times 114 = 287$

And

$u + 26 = 515 + 2 \times 114 = 743$

Then,

$The \: Range = (287,743)$

Final Answers :-

15.73 %

(287,743)

A printing company charges $5.00 for the first 400 pages printed. For each page printed over 400, the customer is charged an add

Vadim26 [7]

Answer:

Step-by-step explanation:

Up to 400 pages, the cost is fixed at 5.00 dollars

After 400 pages the cost is 0.01 cents/page

It's not A. 400 is the number of pages. It is not a cost.
It's not B either. B means that no matter how many pages you print, it's going to cost 5 dollars + the number of pages times 1 cent.
C is not the answer. It is really just an answer put it. You pay 1 cent for each page between 400 and what you printed.
I think D is the answer, but if you get a negative number, then the cost is 5 dollars

Figure TUVW ≅ figure ABCD, AB = 12, CD = 6, and DA = 4.

Olegator [25]

The measure of VW is 6. It's because since the figures are congruent their names are written in correspondence ....so since VW corresponds to CD , the answer must be 6.
