Answer:
D???
Step-by-step explanation:
D????
stand·ard de·vi·a·tion
/ˈstandərd ˌdēvēˈāSHən/
nounSTATISTICS
a quantity calculated to indicate the extent of deviation for a group as a whole.
We know, S = n/2 [ a + l ]
Here, a = 45
l = 108
Calculation of n:
a(n) = a + (n - 1)d
108 = 45 + (n - 1)1
108 - 45 = n - 1
63 + 1 = n
n = 64
Now, substitute in the expression:
S = 64/2 [ 45 + 108 ]
S = 32 [ 153 ]
S = 4896
In short, Your Answer would be 4896
Hope this helps!
