Answer:
26.13 ft^2
Step-by-step explanation:
The area of the triangle is (1/2)(height)(base) = (1/2)(4)(6) = 12. (The base is 6 because it is made up of two radii of the semicircle.)
The area of a whole circle is pi(radius)^2.
Area of whole circle is pi(3^2) = 9pi. But you have only half a circle, so its area is 4.5pi.
Using 3.14 to approximate pi, the area of the semicircle is 4.5(3.14) = 14.13.
Adding this to the area of the triangle, you get a total area
14.13 + 12 = 26.13 ft^2

1. First of all arrange the data set in either ascending or descending order.
12, 19, 24, 26, 31, 38, 53. N = 7 (number of data items)
Median position = 1/2(N + 1)th item = 1/2(7 + 1)th item = 1/2(8)th item = 4th item = 26
First quatile = 1/4(N + 1)th item = 1/4(7 + 1)th item = 1/4(8)th item = 2nd item = 19
Third quatile = 3/4(N + 1)th item = 3/4(7 + 1)th item = 3/4(8)th item = 6th item = 38
Interquatile range = Third quartile - first quatile = 38 - 19 = 19
The difference between a population distribution and sampling a distribution
Definition: The Population Distribution is a form of probability distribution that measures the frequency with which the items or variables that make up the population are drawn or expected to be drawn for a given research study.
Defintion: The Sampling Distribution is a form of probability of a random sample out of a group of frequency which is made up of the sample of which the population has been picked out of, making it a partial research study
