Answer:
you'd get the expression 6.37+7.8k
1/5/12 because,
3x4=12,4x2=8 witch would be 8/12 the 3x3=9+the 12=9/12. 9/12+8/12=1/5/12 so the path is 1/5/12.

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.
