Answer: 2.845
Step-by-step explanation:
The formula to find the standard deviation is given by :-
, where p is the probability of getting success in each trial and n is the sample size.
Given : Sample size : n=110
The proportion of employees older than 55 and considering retirement : p=0.08
Then, the standard deviation is given by :-
Hence, the standard deviation for the sampling distribution of the sample proportions is 2.845.
Answer:
Step-by-step explanation:
20 + 6 + 30 + 6
or
10(2) + 6(2) + 15(2)
or
25 + 37
<span>y = 2x + 15
x = 6 + 3y
<span>y/2 = 3 − x
these are all linear anything with Y=mx+B</span></span>
Answer:
125 meter.
Step-by-step explanation:
After Reading the question we can draw the figure which is triangle XPS
given below.
The point S denotes the Surveyor who is at distance 200 from the south shore(P) and this point P is at y distance from North shore (X) and also the angle given is 32 degree.
So in triangle XPS right angled at P
60 I think, because it’s base times height divided by two
