A. Given
b. Substituition Property (replaces x with the definition of x=8)
c. Subtraction Property of Equality (-1-88=-89)
d. Division Property of Equality (isolating y)
e. Symmetric Property of Equality (a=b -> b=a)
so the second option
Random sampling is defined as a method of selecting a sample from any population in such a way that every selected sample had a predetermined probability of being selected.
So,the true statements for this scenario are :
The owner chooses 20 of the slips of paper without looking.
The owner sends a survey to all clients whose phone number ends in 5.
25 pi
Step-by-step explanation:
If the circumference equals 10pi
And to calculate the circumference is pi multiplied by diameter then the diameter must be 10
The radius is half the diameter so it is 5
To calculate the radius, you have to multiply pi by the radius squared
Which is pi × 5^2
So the answer is 25 × pi
And simply put : 25pi
