About 80% of all female heart transplant patients will survive for at least 3 years Ninety female heart transplant patients are randomly selected What is the probability that
the sample proportion surviving for at least 3 years will be less than 74% Assume the sampling distribution of sample proportions is a normal distribution. The mean of the
sample proportion is equal to the population proportion and the standard deviation is equal to
pg
n
The probability that the sample proportion surviving for at least 3 years will be loss than 74% is (Round to four decimal places as needed)

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

step-by-step explanation:

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
