Answer:
The mean of T is 10 seconds
Step-by-step explanation:
The given parameters are;
The mean completion time of each step, μ = 10 seconds
The standard deviation, σ = 5 seconds
Each step is independent from the other steps
The variable that represents the total completion time for the three steps = T
We have the mean of T, , given by the combined mean as follows;
Where;
n₁ = n₂ = n₃ = 1, each step is taken only once, we have;
Therefore, the mean of T = 10 seconds
Hey there!
Our formula for cylinder area is:
π
h , with r being the radius and h being the height.
When we plug in our values, we get:
A =
A = π(144)(13)
A = 1872π
Therefore, your answer is B, 1872.
Hope this helps!
