Answer:
h = 32.2 ft
Step-by-step explanation:
Since we have a right triangle, to get the value of h, we will have to use the appropriate trigonometric ratio
From the diagram given, h faces the angle and that makes it the opposite side
62.5 ft faces the right angle and that makes it the hypotenuse
The trigonometric ratio that connects the two is the sine
thus, we have it that;
sine 31 = h/62.5
h = 62.5 * sin 31
h = 32.2 ft
Answer: 106.5
Step-by-step explanation:
We know that, Confidence interval for population mean is given by :-
( Sample mean - Margin of error , Sample mean + Margin of error)
Given: confidence interval is (92.3, 120.7).
i.e. Sample mean - Margin of error = 92.3 (i)
Sample mean + Margin of error = 120.7 (ii)
Adding (i) and (ii) , we get
2( Sample mean ) = 213
⇒ Sample mean = 106.5
Hence, the sample mean = 106.5
