You know that the average college student eats 0.75 pounds of food at lunch. If the standard deviation is 0.2 pounds of food, th
Fynjy0 [20]

Answer: $53.95

Step-by-step explanation:

Given: \mu=0.75 pounds

\sigma= 0.2 pounds

n= 50

Two tailed critical z-value for 90% confidence level = 1.645

Let x be the total amount of food that a cafeteria should have on hand to be 90 percent confident that it will not run out of food .

z-score = \dfrac{x-\mu}{\sigma} =\dfrac{x-0.75}{0.2}

Then, \dfrac{x-0.75}{0.2}=1.645

x-0.75=1.645\times0.2\\\\\Riightarrow\ x-0.75=0.329\\\\\Rightarrow\ x= 0.329+0.75\\\\\Rightarrow\ x= 1.079

Foe 50 students, total amount of food = 1.079 x 50 = $53.95

hence, the cafeteria should have food of amount $53.95 so that it is be 90 percent confident that it will not run out of food.

8*{[7+4)*2-[(11-7)*4]}
Rzqust [24]

Answer:

(8 (-1))

Step-by-step explanation:

Simplify the following:

8 (7 + 4×2 - 4 (11 - 7))

11 - 7 = 4:

8 (7 + 4×2 - 44)

4×2 = 8:

8 (7 + 8 - 4×4)

-4×4 = -16:

8 (7 + 8 + -16)

7 + 8 = 15:

8 (15 - 16)

15 - 16 = -(16 - 15):

8 (-(16 - 15))

| 1 | 6

- | 1 | 5

| 0 | 1:

8 (-1)

8 (-1) = (8 (-1)):

Answer: (8 (-1))
