Answer:
778
Step-by-step explanation:
We have the length of stay as X
X~N (9,(2.4))
The sample is given as n = 1000
P(7<x<14) is what we are trying to get
P(7-9/2.4 < x-9/2.4 < 14-9/2.4)
= P(-0.83<z<2.08)
P(z<2.08)-p(z<-0.83)
When we go to the z table,
0.981-0.0203
= 0.778
0.778x1000
= 778
So in conclusion, 778 of these guests can be expected to stay between 7 and 14 days.
Answer:
Step-by-step explanation:
w = 3x + 7y
First we have to get 7y by itself
Subtract 3x from both sides:
w - 3x = 3x + 7y - 3x
w - 3x = 7y
Now we have to get y by itself, so divide both sides by 7
w - 3x/7 = 7y/7
w/7 - 3x/7 = y
y = w/7 - 3x/7
