Answer:
52
Step-by-step explanation:
Given that :
Mean (m) = 78
Standard deviation (s) = 13
Score that is 2 standard deviations below the mean
Using the relation :
Zscore = (x - m) / s
2 standard deviations below the mean means a Zscore of - 2
Hence,
-2 = (x - 78) / 13
Cross multiply
-2 * 13 = x - 78
-26 = x - 78
x = - 26 + 78
x = 52
Score which is 2 standard deviations below the mean is 52
If
is the common difference between terms in the sequence
, then
...
You're told that
(the sum of the first 16 terms in the sequence, presumably). Well, we know that

so that we have
So we get
You can use fraction so it’ll be 628/1300 which simplified ends up 157/325
