Answer:
V =65416.666666 cm^3
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
The diameter is 50 so the radius is 1/2 of the diameter
r = 1/2 (50) = 25
V = 4/3 ( pi) (25)^3
V = 4/3 (pi) 15625
V =20833.3333 pi
Using 3.14 for pi
V =65416.666666 cm^3
We don’t know the value for the population, so we must estimate the standard error using the data from the sample. Standard error = sqrt(p(1 - p)/n), where p is the proportion of yes and n is sample size. Margin of error = z* * standard error, z* = 1.64, so margin of error is 0.053. A sample size less than 10% of the population is needed to make an inference, thus, d is the correct answer. If this was confusing, please don’t hesitate to comment, hope this helps!
prime #is when there is only 1 set of numbers that you can multiply to get that number
so it could be 127 because it is prim and only 1x127 woeks
