, ![\angle C = 114^{\circ}](https://tex.z-dn.net/?f=%5Cangle%20C%20%3D%20114%5E%7B%5Ccirc%7D)
Step-by-step explanation:
From Euclidean Geometry, parallelograms satisfy the following properties:
1)
,
2) ![\angle A +\angle D = \angle D + \angle C = \angle C +\angle B = \angle A+\angle B = 180 ^{\circ}](https://tex.z-dn.net/?f=%5Cangle%20A%20%2B%5Cangle%20D%20%3D%20%5Cangle%20D%20%2B%20%5Cangle%20C%20%3D%20%5Cangle%20C%20%2B%5Cangle%20B%20%3D%20%5Cangle%20A%2B%5Cangle%20B%20%3D%20180%20%5E%7B%5Ccirc%7D)

Answer:
![\bar X -2s = 27.12- (2*1.13) =24.86](https://tex.z-dn.net/?f=%20%5Cbar%20X%20-2s%20%3D%2027.12-%20%282%2A1.13%29%20%3D24.86)
![\bar X +2s = 27.12+(2*1.13) =29.38](https://tex.z-dn.net/?f=%20%5Cbar%20X%20%2B2s%20%3D%2027.12%2B%282%2A1.13%29%20%3D29.38)
So if a value is less than 24.86 would be considered significantly low and a value higher than 29.38 would be considered as significantly high.
The value for the analysis is 29.8 and as we can see 29.8>29.38 so then we can consider 29.8 as a value significantly high.
Step-by-step explanation:
For this case we have the mean given
and the deviation ![s= 1.13](https://tex.z-dn.net/?f=%20s%3D%201.13)
The Range Rule of Thumb says "that the range is about four times the standard deviation"
So then we will ave approximately most of the value within 2 deviations from the mean, so we can find the limits considered normally like this:
![\bar X -2s = 27.12- (2*1.13) =24.86](https://tex.z-dn.net/?f=%20%5Cbar%20X%20-2s%20%3D%2027.12-%20%282%2A1.13%29%20%3D24.86)
![\bar X +2s = 27.12+(2*1.13) =29.38](https://tex.z-dn.net/?f=%20%5Cbar%20X%20%2B2s%20%3D%2027.12%2B%282%2A1.13%29%20%3D29.38)
So if a value is less than 24.86 would be considered significantly low and a value higher than 29.38 would be considered as significantly high.
The value for the analysis is 29.8 and as we can see 29.8>29.38 so then we can consider 29.8 as a value significantly high.
Answer:
126∏
Step-by-step explanation:
area = 2 * area of the circle + area of the rectangular surface
area = 2 * r² * ∏ + 2 * r * ∏ * h
area = (2 * r² + 2 * r * h) * ∏
area = (2 * 7² + 2 * 7 * 2) * ∏
