In this situation, you have to use the equation
T = 2π√L / 32
We need to find L so we have:
T / 2π = √L / 32
(T / 2π) ^ 2 = L / 32
L = 32 * (T / 2π) ^ 2
Substitute the values:
L = 32 * (8.72 / (2 * (3.14))) ^ 2
L = 61.69694511 feet
L = 62 feet
So the Answer is
L = 62 feet
The sampling distribution of x has a mean μₓ = <u> μ </u> and standard deviation σₓ = <u> σ/√n </u>.
In the question, we are given that a random sample of size n is drawn from a large population with mean μ and standard deviation σ.
We are asked to find the mean and the standard deviation for the sampling distribution of the variable x for this sample.
The sample mean is regularly distributed, with a mean μₓ = μ and standard deviation σₓ = σ/√n, where n is the sample size, for samples of any size taken from populations that have a normal distribution.
Thus, the sampling distribution of x has a mean μₓ= <u> μ </u> and standard deviation σₓ= <u> σ/√n </u>.

Answer:
z=3
Step-by-step explanation:
Add 3z and 2z
5z-5=25-5z
Add 5z on both sides to eliminate the -5z on the RHS
10z-5=25
Add 5 on both sides to eliminate the -5 on the LHS
10z=30
Divide by 10
z=3
