Assuming a spherical Earth, the circumference varies as the cosine of the latitude. Your latitude is
arccos(2/3) ≈ 48.1897° ≈ 48° 11' 22.9"
_____
North or South, it doesn't matter.
Because a rectangle has four sides and the opposite sides are the same length, you can simply multiply each of the given sides (5 5/8 feet and 6 1/4 feet) by 2, and then add them together.
5 5/8 × 2 = 11 1/4.
6 1/4 × 2 = 12 1/2
11 1/4 + 12 1/2 = 23 3/4 or 23.75
Therefore, the perimeter of the rectangle is 23.75 feet.

Question 18:
arc SRQ = 360° - 98° - 115° = 147°
y = 147°/2 = 73.5°
arc SPQ = 98° + 115° = 213°
x = 213°/2 = 106.5°

Answer:
H0 : p = 0.75 against H1: p > 0.75 One tailed test.
Step-by-step explanation:
We state our null and alternative hypotheses as
H0 : p = 0.75 against H1: p > 0.75 One tailed test.
In this case H0 is not defined as p≤ 0.75 because the acceptance and rejection regions cannot be set up. Therefore we take the exact value of H0 : p= 0.75.
The claim is that the probability of the workers getting their job through the internet is greater than 75% or 0.75.
As H0 is supposed to be less than we choose H1 to be greater than equality.
