Answer:
0.1469
Step-by-step explanation:
Given from the question;
Mean=8.4 hrs=μ
Standard deviation=1.8 hrs=δ
Sample size, n=40
Let x=8.7
z=(x-μ)÷(δ÷√n)
Find z(8.7)
z=(8.7-8.4)÷(1.8÷√40)
z={0.3×√40}÷1.8=1.05409
z=1.0541
Read from the standard normal probabilities table
P(z>1.0541)
=0.1459

Answer:
574.82 cubic yards
Step-by-step explanation:
The diameter of the cone =14 yards
The angle between the height and slant height measures 32 degrees.
First, we determine the height of the cone using trigonometry.
In Right Triangle AOB,
The volume is about 575 cubic yards.
I googled it because I wasn’t sure if there’s decimals needed but with the raw number I got -0.69333333333
Hope it helped.
