Answer:
0.1875
Step-by-step explanation:
σM=σ/√N
=8/√7500
=8/86.608
=0.092
Z=(x-μ)/σ/√N
=(25.5-36)/8/√7500
=-10.5/0.0092=-1141.304
Z score = -1.3125
=(27-36)/8/√7500
=
=9/0.0092=978.261
Z score= -1.125
-1.125-(-1.3125)=-1.125+1.3125)= 0.1875
The probability that the sample mean will be between 25.5 and 27 years
P(between 25.5 and 27) = 0.1875
If wrong i apologize but for that equation i got the answer K=117
Answer:
200 miles
Step-by-step explanation:
Set up a cost equation for each plan using x for miles.
Set the equations equal.
Solve for x, the miles.
For a 1 day rental.
Plan A:
C = 0.18x + 30
Plan B:
C = 66
0.18x + 30 = 66
0.18x = 36
x = 36/0.18
x = 200
Answer: 200 miles
The length of VX equals to 80
Below I show my work of how I found the missing length.
To find the missing length, you pick the starting location. Then go in any direction and then do the same to the other side. Then write a ratio.
I decided to start at 46 and then go downward.
46/23=x/17
Then you cross multiply
43*17=x*23
782=23x
Divide 23 on both sides
X=34.
Then add 34 by 46 to get the length of VX.
Below is a picture of notes on how to solve these types of problems.
