Step-by-step explanation:
plug in 1 and 4 for x and y
(4)=2(1)-5
then do the math
4=2-5
4 does not equal -3 therefore it is not a solution
Okay. In order to do this problem, you really need to condense it down to the hour. Since this is in months we want to find the hourly rate of pay. If you take her monthly salary and divide it by the monthly job hours, you are able to find the hourly rate of pay, which is $10 an hour.
Answer:
ans=13.59%
Step-by-step explanation:
The 68-95-99.7 rule states that, when X is an observation from a random bell-shaped (normally distributed) value with mean and standard deviation , we have these following probabilities
In our problem, we have that:
The distribution of the number of months in service for the fleet of cars is bell-shaped and has a mean of 53 months and a standard deviation of 11 months
So
So:
-----------
-----
What is the approximate percentage of cars that remain in service between 64 and 75 months?
Between 64 and 75 minutes is between one and two standard deviations above the mean.
We have subtracted by is the percentage of cars that remain in service between one and two standard deviation, both above and below the mean.
To find just the percentage above the mean, we divide this value by 2
So:
The approximate percentage of cars that remain in service between 64 and 75 months is 13.59%.
For some base area B and height h, the volume of a pyramid is
... V = (1/3)Bh
For the same base area and height, the volume of a rectangular prism is
... V = Bh
You will note that the factor of 1/3 is missing, meaning that the volume of the prism is 3 times the volume of the same-dimensions pyramid.
The prism has a volume of 3×(8 cm³) = 24 cm³.
