The surface area of a rectangular prism is 32 square inches. The volume of the prism is 12 cubic inches. The sum of all edge len

Goryan [66]

Answer:

36 cubic inches.

Step-by-step explanation:

Let the length, width and height of the rectangular prism are a, b, c respectively.

So, surface area, 2(ab + bc + ca) = 32 {Given} ............ (1)

Volume, abc = 12 {Given} ............ (2)

And, the sum of all the edges, 4(a + b + c) = 28 {Given} .......... (3)

Now, if the length width and height are increased by 1 inch, then the volume of the prism will be = (a + 1)(b + 1)(c + 1)

= abc + (ab + bc + ca) + (a + b + c) + 1

= 12 + 16 + 7 + 1 {From equations (1), (2) and (3)}

= 36 cubic inches. (Answer)

the standard deviation of 100 random samples of the same size is approximated to be 0.98. what is the margin of error

pogonyaev

Answer:

MOE= ± 0.098

Step-by-step explanation:

-The margin of error is calculated using the formula:

$MOE=\pm \frac{\sigma}{\sqrt{n}}$

#Substitute to solve for MOE:

$MOE=\pm \frac{\sigma}{\sqrt{n}}\\\\=\frac{0.98}{\sqrt{100}}\\\\=\pm 0.098$

Hence, the margin of error is ± 0.098
