Answer:

2x + 14

Step-by-step explanation:

To evaluate h(x + 5) substitute x = x + 5 into h(x), that is

h(x + 5) = 2(x + 5) + 4 = 2x + 10 + 4 = 2x + 14

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)

Create values for a and b so that ab is negative and a−b is positive.

Anna007 [38]

for a put 6 and b put -9

Explain: 6(-9) is equal to -54

and 6- -9 is 15 because the minus turns into a plus sign and the negative number turns into a positive number.
