Answer with explanation:
Sum of interior angles of any polygon having , n sides = (n-2)×180°
It is given that, sum of interior of any polygon =300°
A.T.Q
→ (n-2)×180=300
→Means that ,number of sides of the polygon is a fraction,which is Impossible.
Hence, we can conclude that,it is Impossible to have, 300 degrees in the sum of the interior angles of a polygon.
Option C: Never
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
