Answer:
B. 12.5
Step-by-step explanation:
We have the lowe confidence interval = 185
The upper confidence interval = 210
Mean of X = (lower confidence + upper confidence interval)/2
Mean of X = 185 + 210/2
= 197.5
The margin of error = the upper confidence interval - mean of X
= 210-197.5
= 12.5
[2+(9x3)]x3
Solve for parentheses
[2+(27)]x3
Brackets are solved before the rest of the equation, but always parentheses first
[29]x3=81
The answer is 81.
Hope this helps, and hope I was the brainliest! :)
