sine is opposite side over hypotenuse and cosine is adjacent side over hypotenuse
Answer:
Total area = 1500 ft^2 + 156.25π ft^2, or approx. 1990.9 ft^2
Step-by-step explanation:
The area of the rectangular shape is (25 ft)(60 ft) = 1500 ft^2.
The areas enclosed by the half circles are equal to the area of the circle, whose radius is 12.5 ft. This total area is A = πr^2, or
A = π(12.5 ft)^2 = 156.25π ft^2.
Now add together the area of the circle and the area of the rectangle:
Total area = 1500 ft^2 + 156.25π ft^2, or approx. 1990.9 ft^2.
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>.
