A candle holder is in the shape of a triangular pyramid. The area of the base is 15 in2
EleoNora [17]

The volume of candle holder is 30 inches cubed.

Step-by-step explanation:

Given,

Area of base = A = 15 square inches

Height of candle holder = H = 6 inches

As the holder is in shape of triangular pyramid, therefore,

Volume of candle holder = \frac{1}{3}AH

Volume of candle holder = \frac{1}{3}*15*6

Volume of candle holder = \frac{90}{3}=30\ in^3

The volume of candle holder is 30 inches cubed.

To estimate μ, the mean salary of full professors at American colleges and universities, you obtain the salaries of a random sam
GenaCL600 [577]

Answer:

<h3>73220±566.72</h3>

Step-by-step explanation:

The formula for calculating the confidence interval is expressed as;

CI = xbar ± z*s/√n

xbar is the sample mean =  $73,220

z is the z score at 99% CI = 2.576

s is the standard deviation = $4400

n is the sample size = 400

Substitute the given values into the formula;

CI = 73,220 ± 2.576*4400/√400

CI = 73,220 ± 2.576*4400/20

CI = 73,220± (2.576*220)

CI = 73220±566.72

Hence a 99% confidence interval for μ is 73220±566.72
