Answer:
(34, 48)
Step-by-step explanation:
According to the Empirical Rule, 95% of normally distributed data lie within two standard deviations of the mean. That, in turn, means 95% of the data in this problem lie within 2(3.5 min), or 7 min, of the mean:
41 - 7 < mean < 41 + 7, or
34 < mean < 48, or simply (34, 48)
The answer would be 54, because A= PQ over 2 = 9 x 12 over 2 = 54
Answer:
-8.57142857143
Step-by-step explanation:
-8.57142857143
It would be 9 because 2 x 3 = 6 and then 6 + 3 = 9
