I don’t really see a question-
Answer:
cubic inches
Step-by-step explanation:
Diameter is increasing at 3 inches more than time, When t = 3
Diameter (d) = 3+3 = 6
d = 6
Radius is HALF of diameter, so
r = 6/2 = 3
Now, the volume of a sphere is given by the formula:
Putting r = 3, we get:
The volume would be 36π
Answer:
Sample proportion ; phat
x / n
Step-by-step explanation:
The sample proportion may be explained as a proportional representation of part of the population or larger sample which have a certain character or exhibit a particular trait.
The sample proportion is expressed Mathematically as ;
phat = x / n
x = number of subjects with a specified characteristic ;
n = total sample size
For instance ;
The proportion of black balls in a sample of 100 balls is 15 ; the sample proportion of bla k balls will be :
phat = x / n = 15 / 100 = 0.15
