Answer:

-2

Step-by-step explanation:

-6 ( x - 8) = 60

• divide -6 on both sides

-6 and -6 cancel out and 60 ÷ -6 = -10

• your new equation is now x - 8 = -10

• add 8 to both sides x - 8 = -10

+8. +8

• x = -2

Daniel wanted to know his approximate score on the final exam for his mathematics class. His professor hinted that his score was

Marizza181 [45]

Answer:

The raw score for his exam grade is 99.69.

Step-by-step explanation:

Given : The professor announced that the mean for the class final exam was 88 with a standard deviation of 7. Given Daniel's z score of 1.67.

To find : What is the raw score for his exam grade?

Solution :

The formula use to find the z-score is

$z=\dfrac{x-\mu}{\sigma}$

Where, z=1.67 is the z-score

$\mu=88$ is the means

$\sigma=7$ is the standard deviation

x is the raw score for his exam grade

Substitute the values,

$1.67=\dfrac{x-88}{7}$

$1.67\times 7=x-88$

$11.69=x-88$

$x=88+11.69$

$x=99.69$

Therefore, the raw score for his exam grade is 99.69.

The length of a rectangle is 5 inches less than twice its width. The perimeter of the rectangle is 26 inches. What is the width

Yakvenalex [24]

Answer:

w= 6

Step-by-step explanation:

I just started by making an educated guess using the values already given. Then I inserted that into the problem to see if it worked.

L= 2w - 5

I used 6 as a random, educated guess for the value of w.

L = 2(6) - 5

L = 12-5

L = 7

Then, multiply L by 2 to account for both side lengths of the rectangle.

7(2)= 14

Subtract that value from the total perimeter to find what the width must equal.

26 - 14 = 12

Divide that answer by 2 since there are two sides for width.

12/2 = 6

I know this was kind of long, but I hope it helps! :)
