Answer:
Step-by-step explanation:
Assuming We want to evaluate
When y=6 and z=3.
We substitute to get:
We multiply to get:
We simplify the denominator to get:
Reduce the first fraction:
Add the numerator and keep one denominator for they are like fractions
Write as a mixed number:
Answer:
the correct answer is a because it shows more evidence for itnn
Step-by-step explanation:
and the explanation for this question is that it's really simple and easy.
C because if you look at the intercept it’s a y and the y inception is equivalent to 4 so y=4x-14
P = 0.11
1-p = .89
n = 200
mean = n*p = 22
std dev = n*sqrt(p(1-p)/n) = 4.425
find z values for standard normal distribution
Z= (30-22)/4.425 = 1/808
look up table to find P(Z less than 1.808) which is same P(x less than 30)
for 2nd part, you need 2 Z values
Z1 = (25-22) / 4.425 = 0.678
Z2 = (15-22) / 4.425 = -1.58
P(-1.58 less than Z less than 0.678) = P(Z less than .678) - P(Z less than - 1.58)
