Suppose the president has a 60% approval rating among voters. Twelve voters are randomly selected and asked if they approve of the president. The population is so large that, while sampling is not done with replacement, this does little to affect the independence of the trials. We want to know the probability that seven of the 12 voters approve of the president.

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

im guessing (23,14). hope this : )
