Answer: Circumference = 7.85 inches
Concept:
Here, we need to know the idea of circumference.
The circumference is the perimeter of a circle. The perimeter is the curve length around any closed figure.
Circumference = 2πr
r = radius
π = constant
Solve:
<u>Given information</u>
r = (1/2) d = (1/2) (2.5) = 1.25 inches
π = 3.14
<u>Given formula</u>
Circumference = 2πr
<u>Substitute values into the formula</u>
Circumference = 2 · (3.14) · (1.25)
<u>Simplify by multiplication</u>
Circumference = (2.5) · (2.14)
Circumference = 
Hope this helps!! :)

Dependency: A variable whose value depends on the value assigned to another variable (independent variable).
Correlation: The relationship between two or more variables is considered as correlation.
In statistics, when we talk about dependency, we are referring to any statistical relationship between two random variables or two sets of data. Correlation, on the other hand refers to any of a broad class of statistical relationships involving dependence.
Answer:
59 patients
Step-by-step explanation:
Total patients Sam saw in a week = 236
Percentage of patients near-sighted = 25%
How many of the patients Sam saw were near-sighted?
Number of patients near-sighted = 25% of 236
= 25/100 × 236
= 0.25 × 236
= 59
Number of patients near-sighted = 59 patients
The number of patients Sam saw in a week that were near-sighted is 59 patients
Domain is all Real Numbers and Range is from 0, but not including 0, to infinity. So it would be the first one
