Nearly 7,000 children acquired disease Z in the last year. Among the population of all children who acquired disease Z in the last year, suppose that (unknown to researchers) 1400 of them (20%) also acquired a secondary skin infection. A researcher intends to take a simple random sample of 50 children who had the disease last year and record whether or not the person also had a secondary infection. Let X be the number of children in the sample who report having a secondary infection. The variance of this distribution is .

disease z is pretty deadly

Step-by-step explanation:

the factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24. hope this ! mark brainliest! you v much! : )

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
