A. Descriptive statistics
Descriptive statistics involve summarizing and describing data, such as calculating measures of central tendency (like the average height) or measures of variability (like the range or standard deviation) for a given sample or dataset. In this case, you are describing the characteristics of a specific group of basketball players, which falls under descriptive statistics.
The least number of students who could have been taking both courses is 0.
The greatestnumber of students who could be taking both courses is 30.
The greatestnumber of students who could have been taking neither course is 30.
The process of subtracting one number from another is known as subtraction.
Given that, there are a total of 150 students out of which 90 were taking algebra and 30 were taking biology.
The remaining students are:
150 - 90 - 30
= 30
Now, the remaining 30 students may take both subjects or neither.
Therefore, the least number of students who could have been taking both courses is 0.
The greatestnumber of students who could be taking both courses is 30.
The greatestnumber of students who could have been taking neither course is 30.

Answer:
Amount of plastic need to cover paper role = 565.2 inches
Step-by-step explanation:
Given:
Diameter of paper role = 10 inch
Height of paper role = 13 inch
Find:
Amount of plastic need to cover paper role
Computation:
Radius of paper role = Diameter of paper role / 2
Radius of paper role = 10 / 2
Radius of paper role = 5 inch
Amount of plastic need to cover paper role = Total surface area of cylinder
Amount of plastic need to cover paper role = 2πr(h+r)
Amount of plastic need to cover paper role = 2(3.14)(5)(13+5)
Amount of plastic need to cover paper role = (3.14)(10)(18)
Amount of plastic need to cover paper role = 565.2 inches
