Answer:

V = 432 cm^3

SA = 438 cm^2

Step-by-step explanation:

The volume of a rectangular prism is represented by the formula:

V = lwh

Where V is the volume, l is the length, w is the width, and h is the height.

You can substitute the values given:

V = 3 * 9 * 16

V = 432 cm^3

The surface area of a rectangular prism can represented by the formula:

SA = 2(lw + wh + lh)

Where SA is the surface area, l is the length, w is the width, and h is the height. You can substitute the given values:

SA = 2(3 * 9 + 3 * 16 + 9 * 16)

SA = 2(27 + 48 + 144)

SA = 2(219)

SA = 438 cm^2

Find the interquartile range for a data set having the five-number summary: 3.5, 10.4, 16, 21.7, 27.7
vlabodo [156]

Answer: 17.75

Step-by-step explanation:

The interquartile range(IQR) is the 3rd quartile - the 1st quartile.

How to get quartiles:

First get the median:

3.5, 10.4, 16, 21.7, 27.7

10.4, 16, 21.7

16

Then find the median of the first half of data(3.5, 10.4)

(3.5+10.4)/2 = 6.95

Then find the median of the last half of data(21.7, 27.7)

(21.7+27.7)/2 = 24.7

Then to get the IQR subtract 6.95 from 24.7 to get 17.75

To find 15% of something, you would multiply 0.15 by the number you are trying to find 15% of.
