Answer:

B. 72 yd^3

Step-by-step explanation:

First we find the area of the base, which is the triangle.

Area = (1/2)(base)(height)

A = 1/2(3)(8) = 1/2(24) = 12

Multiply that base area by the height (6)

12 x 6 = 72

What is the range of this set of heights in centimeters? {140, 166, 132, 165, 152, 168, 181, 158, 173, 171, 180, 182, 163, 177,

Sholpan [36]

Answer:

Step-by-step explanation:

Given:

140, 166, 132, 165, 152, 168, 181, 158, 173, 171, 180, 182, 163, 177, 180, 142, 147, 149, 178

Arranging in ascending order (from the lowest to the highest)

= 132, 140, 142, 147, 149, 152, 158, 163, 165, 166, 168, 171, 173, 177, 178, 180, 180 181, 182

Range = highest number - lowest number

= 182 - 132

= 50

The standard deviation of the distribution of sample means is _______.

luda_lava [24]

Answer:

Standard error

Step-by-step explanation:

The standard deviation of the distribution of sample means is called the standard error of the means.

It is denoted by: $\sigma_{\bar X}$

The standard error is calculated using the formula: $\sigma_{\bar X}=\frac{\sigma}{\sqrt{n} }$

where n is the sample size and $\sigma$ is the population standard deviation.
