Answer:
for 
Step-by-step explanation:
Given
Shape: Triangle
Dimension: 3x + 2, x^2 and 2x

Required
Determine if it has equal sides
To do this, we simply substitute 4 for x in the given dimensions
<u>3x + 2</u>



<u>x^2 </u>


<u>2x</u>

for 
They are all the same number
The sample std. dev. will be (14 inches) / sqrt(49), or (14 inches) / 7, or 2 inches.
Find the z score for 93.8 inches:
93.8 inches - 91.0 inches 2.8 inches
z = ------------------------------------- = ----------------- = 1.4
2 inches 2 inches
Now find the area under the standard normal curve to the left of z = +1.4.
My calculator returns the following:
normalcdf(-100,1.4) = 0.919. This is the probability that the mean annual precipitation during those 49 years will be less than 93.8 inches.
