The depth of the snow at Yellowstone National Park in April at the lower geyser basin was normally distributed with a mean of 3.
Leona [35]

Answer:

X =4.94\ in

Step-by-step explanation:

For a standard normal distribution of mean \mu_z = 0 and \sigma_z = 1

the statistic Z = \frac{X - \mu}{\sigma}

In this problem we look for the value of X that is 2 standard deviations above the mean.

If there are two standard deviations above the mean, then, in the standard normal distribution, the statistic Z = 2.

Then, we clear X.

2 = \frac{X -\mu}{\sigma}\\\\2\sigma = X - \mu\\\\\2\sigma + \mu = X\\\\

Where:

\sigma=0.52\\\\\mu=3.9\\\\X = 2(0.52) + 3.9\\\\X =4.94

Item 1 Find the volume of the prism. A rectangular prism with length of start fraction 4 over 5 end fraction millimeter, width o
nirvana33 [79]

Answer:

The volume of the rectangular prism is 3/20 (or 0.15) mm³.

Step-by-step explanation:

The volume of the rectangular prism can be calculated as follows:

V = l*w*h     (1)

Where:

l: is the length = 4/5 mm

w: is the width = 1/2 mm

h: is the height = 3/8 mm  

By entering the values of l, w, and h into equation (1) we can find the volume:

V = l*w*h = \frac{4}{5} mm*\frac{1}{2} mm*\frac{3}{8} mm = \frac{3}{20} mm^{3} = 0.15 mm^{3}

Therefore, the volume of the rectangular prism is 3/20 (or 0.15) mm³.

I hope it helps you!
