Answer:
.3
Step-by-step explanation:
let x= P(f)
.65= .55+x-.2
P(F)=.3
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.
-8 - 7/ -2 - 3 = -15/-5 = 3
3 it’s the slope
7=3(3) +b
7=9 +b
-9. -9
-2=b
Y=3x-2
Yes I’m agree, because if you find the slope with the formula y2-y1/x2-x1 you can find the slope and if you use the formula y=Mx+b you can find the y- intercept.
Answer: 15.5
Step-by-step explanation:
(10.5-7)+(4x3)
following PEDAS we do operations in parentheses first
10.5-7=3.5
4x3=12
we now have 3.5+12 as our intermediate expression
and 3.5+12 = 15.5
