Answer:
B
Step-by-step explanation:
You use FOIL (first, inner, outer, last). You then see what answer would get 47x for the middle...
(x-6)(8x+1) is the only one that gets 47x.
Then finish solving (x-6)(8x+1) to get 8x - 47x - 6
Answer:
At most 25%
Step-by-step explanation:
The fraction of the distribution that can exceed n standard deviations from the mean is 1/n². For a standard deviation of 5 and a mean of 80, a score of 90 is (90-80)/5 = 2 standard deviations from the mean. Scores better than that can be at most (1/2)² = 1/4 = 25% of the total number of scores.
