Answer:
For this case the mean is given by:

And the standard deviation would be:

Step-by-step explanation:
For this case we have the following info given :
represent the sample size
represent the proportion of business graduate students from private universities had student loans
For this case we want to find the distribution for the sample proportion and we know that this distribution is given by:

And for this case the mean is given by:

And the standard deviation would be:

I will answer assuming that the equation is 4(1-x) < -12+2x
1) 4 - 4x < - 12 + 2x
2) 2x + 4x > 4 + 12
3) 6x > 16
4) x > 16 / 6
5) x > 8 / 3
So the graph is all the real numbers greater than 8/3 which may be represented by a straight line from 8/3 to the right toward infinity

For this you need the formula for a circle:
A=πr2 (pi r squared)
A=π(10) squared
A=(3.14)(10) squared
(remember to square before you multiply - order of operations)
A=(3.14)(10*10)
A=(3.14)(100)
A=314
Hope this helps! :)
Answer:
The ride took 7 1/2 hours to complete.
Step-by-step explanation:
If the bicyclist is going at a constant speed of 6mi/hr it would take 7 1/2 hours to ride 45 miles.
6*7 1/2=45
