Answer: 120 cartons

Step-by-step explanation: Since, the grocery clerk displays 15 cartons at the base of the triangle and one at the top. Therefore, one carton is reduced at previous step and so on. Since, this series is in arithmetic progression. Therefore, 120 cartons are needed for the complete display.

Mama L [17]

If you already know that you have . . .

1$ after week 1
2$ after week 2
4$ after week 3
8$ after week 4

. . . You can then tell that every week the money you save doubles (times 2)

So to continue . . . .
16$ after week 5
32$ after week 6
64$ after week 7
128$ after week 8
256$ after week 9
512$ after week 10

You will then know that after ten weeks u will have 512$ which is answer choice D.

Hope this helps! :)

Voltage sags and swells. Refer to the Electrical Engineering (Vol. 95, 2013) study of transformer voltage sags and swells, Exerc

Artist 52 [7]

Answer:

a. z-score for the number of sags for this transformer is ≈ 1.57 . The number of sags found in this transformer is within the highest 6% of the number of sags found in the transformers.

b. z-score for the number of swells for this transformer is ≈ -3.36. The number of swells found in the transformer is extremely low and within the lowest 1%

Step-by-step explanation:

z score of sags and swells of a randomly selected transformer can be calculated using the equation

z= $\frac{X-M}{s}$ where

X is the number of sags/swells found

M is the mean number of sags/swells

s is the standard deviation

z-score for the number of sags for this transformer is:

z= $\frac{400-353}{30}$ ≈ 1.57

the number of sags found in the transformer is within the highest 6% of the number of sags found in the transformers.

z-score for the number of swells for this transformer is:

z= $\frac{100-184}{25}$ ≈ -3.36

the number of swells found in the transformer is extremely low and within the lowest 1%
