Its 10 cm because 15/9 on one side is 1.6666666 or 5/3 that will have to be your scale factor from going from small to big. So 6 time 5/3 will get you 10.
Answer:
0.0359
Step-by-step explanation:
Data provided:
mean values of three independent times are 15, 30, and 20 minutes
the standard deviations are 2, 1, and 1.6 minutes
Now,
New Mean = 15 + 30 + 25 = 65
Variance = ( standard deviation )²
or
Variance = 2² + 1² + 1.6² = 7.56
therefore,
Standard deviation = √variance
or
Standard deviation = 2.75
Thus,
Z-value = 
or
Z-value = - 1.81
from the Z-table
the Probability of Z ≤ -1.81 = 0.0359
You know that the y is negative and the x is positive (it's the lower right side of a graph)
Answer:
sp with vat=9040
d=20%
vat=13%
mp=?
Step-by-step explanation:
sp with vat=9040
sp+vat%of sp=9040
sp(1+13/100)=9040
sp=9040/1.13=8000
- mp=sp+d%ofmp
- mp-d%ofmp=sp
- mp(1-20/100)=8000
- mp=8000/0.8=10000
