According to the government data, the probability that an adult was never in a museum is 16%. ina random survey of 60 adults, what is the mean and standard deviation of the number that were never in a museum

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
