In a random sample of 68 people, 17 are classified as "successful."
a. Determine the sample proportion, p, of "successful" people.
b. If the population proportion is 0.70, determine the standard error of the proportion.
a. p=
(Type an integer or a decimal.)
(Round to four decimal places as needed.)

what does x eaqual

step-by-step explanation:

thus, the first answer choice, y = sec x, is the correct one

because that’s us why

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
