Answer:
h = 16 inches
Step-by-step explanation:
The surface area of a cylinder is given by
SA = 2 pi r^2 + 2 pi rh
We know the surface area and the radius
1206.4 = 2 ( 3.14) * 8^2 + 2 * 3.14 * 8 *h
1206.4 = 401.92+50.24h
Subtract 401.92 from each side
1206.4-401.92 = 401.92-401.92+50.24h
804.48=50.24h
Divide each side by 50.24
804.48/50.24 =50.24h/50.24
16.01273885=h
x is 8 and y is 1 .I'm sure.
Answer:
There is no statistical evidence to support the claim that the mean is elss than 74.
Step-by-step explanation:
Given that a paint-drying situation in which drying time for a test specimen is normally distributed with s = 6.
The hypotheses H0: µ = 74 and Ha: µ < 74
are to be tested using a random sample of n = 25 observations
a) Z = 
ie. -1.417 std deviations to the left of mean.
b) p value = 0.078241
Since p > 0.01 , our alpha, accept H0
There is no statistical evidence to support the claim that the mean is elss than 74.
The hypotenuse is always double the shortest side.
so if, 2x = 6, then, x (the shortest side) = 6/2. the shortest side is 3 units.
When:
a = b = 0 we have point (0,0).
a = 0 and b ≠ 0 vertical line segment from (0, -b) to (0, b)
a ≠ 0 and b = 0 horizontal line segment from (-a, 0) to (a, 0)
a ≠ 0 and b ≠ 0 a ≠ b ellipse
a ≠ 0 and b ≠ 0 a = b circle
