The area of the sector AOB is 487 and mZAOB = 270 degrees.
Find the radius of Circle O:

Answers

Answer 1

Answer:

Radius of circle = 14.38 unit (Approx.)

Explanation:

Given:

Area of the sector AOB = 487 unit²

Angle of sector AOB = 270°

Find:

Radius of circle

Computation:

Area of the sector = [θ/360][πr²]

Area of the sector AOB = [θ/360][πr²]

487 = [270/360][(3.14)r²]

487 = [0.75][(3.14)r²]

487 = [2.355r²]

r² = 487 / 2.355

r² = 206.80

r = 14.38

Radius of circle = 14.38 unit (Approx.)

A small school with 60 total students records how many of their students attend school on each of the 180
days in a school year. The mean number of students in attendance daily is 55 students and the standard
deviation is 4 students. Suppose that we take random samples of 5 school days and calculate the mean
number of students ĉ in attendance on those days in each sample.
Calculate the mean and standard deviation of the sampling distribution of

Answers

Answer:

The answer is below

Explanation:

Given that the mean of the attendance of the population (μ) = 55 students, and the standard deviation (σ) = 55 students

If repeated random samples of a given size n are taken from a population with a population mean of μ and the population standard deviation of σ,  then the mean of the sample distribution ([tex]\mu_x[/tex]) is population mean μ, while the standard deviation of the sample distribution ([tex]\sigma_x[/tex]) is the population standard deviation divided by the square root of the sample size.

Given a random sample (n) of 5 days, hence:

mean of sampling distribution ([tex]\mu_x[/tex]) = μ = 55 students

standard deviation of the sampling distribution = [tex]\sigma_x[/tex] = [tex]\frac{\sigma}{\sqrt{n} }=\frac{4}{\sqrt{5} } =1.79[/tex]
