Answer:
124.71
Step-by-step explanation:
V=1
/4h√a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4
a,b,c= base sides
h= height
V=1
/4(8)√(6)^4+2(6x6)^2+2(6x6)^2﹣(6)^4+2(6x6)^2﹣(6)^4
V= 124.71

Answer:
0.85
Step-by-step explanation:
The given standard deviation of a population (σ) = 7.8
sample size (N) = 85
We have to find standard error of the mean.
The formula to find standard error of the mean
= (standard deviation of the distribution) / (square root of sample size)
= (σ) / (√N)
= 7.8 / (√85)
= 7.8 / 9.219544457
= 0.8460
= 0.85 (approximately taken to two decimal places)
We have got the required answer.
The standard error of the mean is 0.85.
