Question 16

Gabriel is grading essays. He has 105 essays to grade and it takes him 4 minutes to grade each essay. The number of minutes that Gabriel spends grading each essay is a function of the amount of essays graded.

Select two statements that correctly describe the domain or range of this function.

A

The range is the set of all integers from 0 to 105.

B

The range is the set of all multiples of 4 from 0 to 420.

C

The domain is the set of all multiples of 4 from 0 to 420.

D

The domain is the set of all integers from 0 to 105.

Statement B and D are correct.

Step-by-step explanation:

The number of minutes Gabriel spends grading essays can be presented as a function: f(x) = 4x, where x is the number of graded essays and 4 is the number of minutes Gabriel spends on grading each essay.

By definition, domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes.

So in this case, domain of f(x) is the set of all values of x which is an integer going from 0 to 105. Statement D is accurate.

Range of f(x) is the set of all values that f takes and can be calculated by multiplying 4 with (0,105), equal (0,420). Statement B is accurate.

f(x)=2/3x+4/3 is the answer because is whose power in the senate is equal to the power of the speaker of the house?

step-by-step explanation:

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
