Answer:

15. -2 16. 0 17. undefined

Step-by-step explanation:

Slope of two points can be calculated by (y change) / (x change).

(y1 - y2) / (x1 - x2)

15) (1-5) / (4-2) = -2

16) (6-6) / (1-10) = 0 since y change is 0.

17) (-5-3) / (4-4) = undefined since x change is 0 but you cannot devide by 0.

grin007 [14]

Answer: -1.33 .

Step-by-step explanation:

Formula to find the Z-score :

$Z=\dfrac{\text{Expected value - Mean}}{\text{Standard deviation}}$

Given: Mean = 191 and Standard deviation = 21

Then , the z-score corresponding to the expected value of 163 will be :

$Z=\dfrac{163-191}{21}\\\\=\dfrac{-28}{21}\approx-1.33$

Hence, the z score corresponding to selling 163 inhalers is -1.33 .
