Answer:

3 gallons per mile, slope of 3

Step-by-step explanation:

To find out how many gallons the train uses per mile, look at the point (50,150). If you know that the train used 150 gallons to travel 50 miles, do 150/50 to get an answer of 3 gallons per mile.

For the second part, you know that as x increases by 1 (miles traveled) y (gallons) increases by 3, so therefore the slope is 3. You can also check this value by plugging in the points (150,450) and (50,150) into the m=\frac{x_{2}  - x_{1}}{y_{2}  - y_{1}}

we are given that

A school director Must randomly select 6 teachers to participate in a training session there are 30 teachers at the schoo. The order of selection does not matter.

6 teacheras can be selected out of 30 teacher in {30}_C_6 ways.

{30}_C_6=\frac{30!}{6!24!}\\&#10;\\  {30}_C_6=\frac{25*26*27*28*29*30}{1*2*3*4*5*6}\\&#10;\\  {30}_C_6=593775

Hence the required number of ways is 593775.
