Well, since the exam creator claims that on the same exam, nine times out of ten, seniors will have an average score within 6% of 80%, that means there is a 90% confidence interval. 9 / 10 = .90 = 90% 90% = 1.645 1.645 * .9 = 1.4805 Margin of Error - 1.4805and The margin of error is the distance from x-bar, the center of the confidence interval ,to the end of the interval. This distance is 6% of 80% which is given by: 80×6100=4.8 Therefore the margin of error is 4.8% and the confidence interval is: ({80 - 4.8}%, {80 + 4.8}%)

Hello from MrBillDoesMath!
Answer:
x = 3
Discussion:
(
23 + 3x) + (8x-41) = 15 =>
23 - 41 + 3x + 8x = 15 =>
-18 + 11x = 15 =>
11x = 15 + 18 = 33 =>
x = 33/11 = 3
Thank you,
