Researchers from a large community college in California are interested in understanding the demographics of students enrolled in their online classes. The researchers collected the following data for the 2014/2015 school year. Male Female Total
Online Only 2,000 7,000 9,000
Online and in the class only 8,000 1,000 9,000
Total 10,000 8,000 18,000

What does the data suggest about the relationship between sex and enrollment?

a. Females are more likely to enroll in Online Only courses than males.
b. Females are more likely to enroll in Online and In Class courses than males
c. There are more females enrolled at the community college than males.
d. Females are equally likely as males to enroll in an Online Only course.

a. Females are more likely to enroll in Online Only courses than males.

Step-by-step explanation:

From the data, we have that:

There are 9,000 students that are online only, of which 2,000 are male and 7,000 are female.

There are 9,000 students that are Online and in the class only, of which 8,000 are male and 1,000 are female.

In total, there are 18,000 students, of which 10,000 are male and 8,000 are female.

a. Females are more likely to enroll in Online Only courses than males.

True, 7,000 females compared to 2,000 males in online only courses. This option is the answer to this question.

b. Females are more likely to enroll in Online and In Class courses than males

False, in online and in the class courses, there are 8,000 males and 1,000 females, so females are less likely.

c. There are more females enrolled at the community college than males.

False, there are 10,000 males and 8,000 females.

d. Females are equally likely as males to enroll in an Online Only course.

False, there are 7,000 females compared to 2,000 males in online only courses, so they are more likely, and not equally likely.

6 spoons of sugar for every 21 cups of flour

step-by-step explanation:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
