The volume of a rectangular box is 1600 cubic inches. The height of the box is 8 inches and the length of the box is 2 times lon

Anastasy [175]

Answer:

0.833 feets

Step-by-step explanation:

Given that:

Volume of box = 1600

Heigh of box (H) = 8 inches

Let:

Width of box (W) = x

Length of box (L) = 2x

Volume of box = (Height * width * length)

1600 = (8 * x * 2x)

1600 = 16x²

x² = 1600/16

x² = 100

x = sqrt(100)

x = 10 inches

Hence, width of box in feet:

1 inch = 0.0833 feets

10 inches = (10 * 0.0833) feets

= 0.833 feets

Answer: 83

Step-by-step explanation:

The confidence interval for population mean is given by :-

$\overline{x}\pm E$

Given : The student obtained the following 95% confidence interval (in grams) for the population mean, (862,1028).

Here,

Lower limit of the confidence interval : $\overline{x}-E=862$ (1)

Upper limit of the confidence interval : $\overline{x}+E=1028$ (2)

Subtracting (1) from (2) , we get

$2E=166\\\\\Rightarrow\ E=\dfrac{166}{2}=83$

Hence, the margin of error = 83
