Answer:
The perimeter is 50.26 inches
Step-by-step explanation:
To find the circumference of the half-circle use
d/2
C = 3.14(9 x 2)/2
C = 3.14(18)/2
C = 56.52/2
C = 28.26
P = 5 + 12 + 5 + 28.26
P = 50.26
Point C can be located on points (-3,2)

Answer:
a. 0.1971
Step-by-step explanation:
Z score is used to measure by how many standard deviations the raw score is above or below the mean. It is given by the formula:
![z=\frac{x-\mu}{\sigma}\\ \\Where\ \mu=mean, x=raw\ score, \sigma=standard\ deviation](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D%5C%5C%20%5C%5CWhere%5C%20%5Cmu%3Dmean%2C%20x%3Draw%5C%20score%2C%20%5Csigma%3Dstandard%5C%20deviation)
Given that:
μ = 1050 kWh, σ = 218 kWh
For x = 1100 kWh
![z=\frac{x-\mu}{\sigma}=\frac{1100-1050}{218} =0.23](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D%3D%5Cfrac%7B1100-1050%7D%7B218%7D%20%3D0.23)
For x = 1225 kWh
![z=\frac{x-\mu}{\sigma}=\frac{1225-1050}{218} =0.80](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D%3D%5Cfrac%7B1225-1050%7D%7B218%7D%20%3D0.80)
From the normal distribution table, P(1100 < x < 1225) = P(0.23 < z < 0.8) = P(z < 0.8) - P(z < 0.23) = 0.7881 - 0.5910 = 0.1971
