We are looking at HIV positive rates among rural Chinese farmers. One of the variables studied was education level, which was recorded as 'illiterate," "primary," and "secondary." What type of

variable is education level in this example?

Categorical data.

Step-by-step explanation:

Variables can be classified as:

Quantitative: If the variable assumes numeric values.

Categorical: If the variable assumes labels.

In this question:

'illiterate," "primary," and "secondary" are labels, which means that in this example, education level is an example of categorical data.

is this part of a question or something

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
