Thirty-six percent of U. S. adults have postponed medical checkups or procedures to save money. You randomly select nine U. S. adult. Find the probability that the number of U. S. adults out of the nine who have postponed medical checkups or procedures to save money is exactly 3.

0.2693

Step-by-step explanation:

Thus is a binomial probability problem :

p = 0.36

1 - p = 0.64

n = 9

x = 3

Using the binomial probability relation :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

P(x = 3) = 9C3 * 0.36^3 * 0.64^6

P(x = 3) = 84 * 0.36^3 * 0.64^6

P(x = 3) = 0.2693

the reporter's right

step-by-step explanation:

1/4 = .25 / 25%

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
