Answer:
The upper bound of the confidence interval is 0.34
Step-by-step explanation:
Here in this question, we want to calculate the upper bound of the confidence interval.
We start by calculating the margin of error.
Mathematically, the margin of error = 0.29 -0.24 = 0.05
So to get the upper bound of the confidence interval, we simply add this margin of error to the mean
That would be 0.05 + 0.29 = 0.34
Answer:
12 ft
Step-by-step explanation:
Area = Length * Width
168 = 14 * W
168/14 = W
W = 12 ft
With a calculator or by hand.
Answer:
Below in bold.
Step-by-step explanation:
cos x = adjacent side / hypotenuse
= 8/21
= 0.380952
So m < x = arccos 0.380952
= 67.607
= 68 degrees to nearest degree.
I didn't even have to do any math for this one, it is clearly 20 because that is the only answer above 12 (And it says picks in ALL).
