The answer to the problem is D.61/100
Hope this helps.
Answer:
c. [70.30, 74.70]
Step-by-step explanation:
Confidence interval is a range of values in which there is a specified probability that the value of a parameter lies within that range.
The confidence interval of a statistical data can be written as.
x+/-zr/√n .......1
Given;
Mean gain x = 72.5 cm
Standard deviation r = 4.5 cm
Number of samples n = 16
Confidence interval = 95%
z (at 95% confidence) = 1.96 (from the table)
Substituting the values we have into equation 1;
72.5 +/- 1.96×4.5/√16
72.5 +/- 2.20 cm
[70.30, 74.70]
Therefore, the 95% confidence interval is
[70.30, 74.70] cm

Could you post an image?
I have the variables; I just need the problem.
Answer: AOB
This is because angle AOB on top adds with BOC down below to get the largest angle AOC. See the diagram below.
a = 11(4b + c) Multiply/distribute 11 into (4b + c) [multiply 11 to 4b and c]
a = 44b + 11c Subtract 44b on both sides
a - 44b = 11c Divide 11 on both sides to get "c" by itself
You can simplify it to this(but Idk if you have to):
