Answer:
100
Step-by-step explanation:
We have the sum of first n terms of an AP,
Sn = n/2 [2a+(n−1)d]
Given,
36= 6/2 [2a+(6−1)d]
12=2a+5d ---------(1)
256= 16/2 [2a+(16−1)d]
32=2a+15d ---------(2)
Subtracting, (1) from (2)
32−12=2a+15d−(2a+5d)
20=10d ⟹d=2
Substituting for d in (1),
12=2a+5(2)=2(a+5)
6=a+5 ⟹a=1
∴ The sum of first 10 terms of an AP,
S10 = 10/2 [2(1)+(10−1)2]
S10 =5[2+18]
S10 =100
This is the sum of the first 10 terms.
Hope it will help.
Is there not more to this problem? maybe thats the final answers
The distribution will be skewed to the positive side because the mean is greater than the median.
Mean: 3.7
Median: 3
Answer: B
Answer:
it would be b for 1 since 7 would be negative and the 3 would be positive
Answer:
Set this up as a proportion.
54/n = 75/100
Now solve for n and finish from here.
