Area = Length x Width(height).
You are given the area and the width(height).
You can find the length by dividing the area by the width:
Length = 120 / 3 = 40 feet.
Answer:
0.0359
Step-by-step explanation:
Data provided:
mean values of three independent times are 15, 30, and 20 minutes
the standard deviations are 2, 1, and 1.6 minutes
Now,
New Mean = 15 + 30 + 25 = 65
Variance = ( standard deviation )²
or
Variance = 2² + 1² + 1.6² = 7.56
therefore,
Standard deviation = √variance
or
Standard deviation = 2.75
Thus,
Z-value = 
or
Z-value = - 1.81
from the Z-table
the Probability of Z ≤ -1.81 = 0.0359

If we set the vertex at (0,0) then the curve goes through (30,30)
<span>y = 1/30 x^2 </span>
<span>x^2 = 30y </span>
<span>Since the parabola x^2 = 4py has its focus at y=p, 4p=30 and the mic should be 15/2 inches up from the vertex.</span>
(n -12)(n +3)= 0
n = 12, n = -3
