As your sample size grows larger, the n - 1 adjustment for the standard deviation has a smaller impact on the estimates of standard deviation.
<u>Step-by-step explanation:</u>
The average (mean) of sample's distribution seems to be the same as the distribution mean at which samples were taken. The means of mean distribution will not change. However, the standard deviations for the samples mean is the standard deviations of the primary distribution divided by square roots of the samples size.
The standard deviations of means decreases as the samples size increases. Likewise, when the samples size decreases, the standard deviations for the samples mean increases. So, there is a little impact on standard deviations estimation when sample size increases.
So the radius is 5 cm
and we are given the volume at 225 cm³
now breakdown the volume formula for a cone which is V equals 1/3 Bh
b= pi r squared
now substitute everything in
225 equals 1/3 pi(5)^2 Times h
since we don’t know H that is what we’re solving for
225= 1/3 pi(25) times h
multiple 3/1 on both sides to cancel the 1/3
675= 25(3.14) times h
675= 78.5 (h)
h= 675/78.5
h=8.60 cm
I believe that angle 6 is 108 because I drew to the best of my ability and I see that 3 and 6 are alternate interior angles.
Answer:
60cm²
Step-by-step explanation:
Surface area of a triangular prism = 2B+ph
B is the base area = 6cm²
perimeter p = 12cm
altitude h = 4cm
Substitute
Surface area = 2(6) + 12(4)
Surface area = 12 + 48
Surface area = 60cm²
Answer: C
Step-by-step explanation:
Yes, because the population values appear to be normally distributed
