Answer:
Step-by-step explanation:
At least you know its not false
C = 4900 + 175S
The graph will cross the y-axis at 4900 and show a slope of 175/1 . Good luck graphing. If you choose the right scale, the graph will be easier. Increment by by 500 on the yaxis and 25 on the x-axis.
Answer:
3 11/25 pints of white paint
Step-by-step explanation:
8 6/10 is the same as 43/5
if 3/5 of the total pints are blue then 2/5 are white
so multiply 43/5 x 2/5 to get 86/25 which equals 3 11/25
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%.
