In a large clinical trial, 399,833 children were randomly assigned to two groups. The treatment group consisted of 201,028 children given a vaccine for a certain disease, and 25 of those children developed the disease. The other 198,805 children
were given a placebo, and 78 of those children developed the disease. Consider the vaccine treatment group to be the first sample.

answer: 12,000

step-by-step explanation: first you ar e supposed to add. then multiply then subtract

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
