Step-by-step explanation:
<u>Normal Distribution</u>
Gauss Distribution is one of the most widely-used continuous probability distribution to characterize random events. The curve of the function is called the bell curve.
The standard Normal Distribution is a special case where the mean and the standard deviation . The values of the cumulative normal distribution cannot be computed by simple calculations, we must use tables of digital implementations integrated with tools like Excel or any online resource.
The entry for standard normal distribution is a parameter called the z-score, computed like shown below
The values provided in our problem are
Computing z results
By using any of the aforementioned resources, we compute the left-tail probability
We choose the first option 5%

Answer:
200 in²
Step-by-step explanation:
The face consists of two 10 in squares. Each of those will have an area of ...
(10 in)² = 100 in²
so the two of them together will have an area of ...
2 × 100 in² = 200 in²
The markup for the sofa would be $38.80. 40% of 97 is 38.8. so you would add 38.8 to 97 to get the final price. 97 + 38.8=135.8
hope that helped!
