Answer with explanation:</h2>
Consider a sampling distribution with p equals 0.12 and samples of size n each.
Then, formula for mean = p
Formula for standard deviation= 
(a) For a random sample of size n equals 5000.
Mean = 0.12
Standard deviation= 
(b) For a random sample of size n equals 1000.
Mean = 0.12
Standard deviation= 
(c) For a random sample of size n equals 500.
Mean = 0.12
Standard deviation= 
Find the area of each shape first like first the middle square then the triangles and multiply the triangles by 4
2=6
3=9
9=27
You just times the number in box X three times
The volume of a sphere is (4πr^3)/3 and since r=d/2, volume of a given sphere with respect to its diameter is:
V=(4πd^3)/24
V=(πd^3)/6 in this case d=8.65 so
V≈338.88 in^3 (to the nearest hundredth)
Solve for the two velocities:
with the current = 48/6 = 8 mph
against the current = 48/8 = 6 mph
bv= boat velocity in still water
cv = current velocity
A) bv -cv = 6mph
B) bv + cv = 8mph
Adding both equations
2 * bv = 14 mph
boat velocity = 7 mph
current velocity = 1 mph
