John and Adam were curious to find out if PHS varsity soccer players had a lower resting heart rate than other athletes at Prospect that have an average resting heart rate of 60 pulses per minute. John and Adam took a random sample of 8 varsity soccer players and found their average resting heart rate to be 52 beats per minute with a standard deviation of 7.3094. Do these data provide convincing evidence at the a=0.05 level that Prospect varsity soccer players have a lower resting heart rate than other PHS athletes? ASSUME ALL CONDITIONS ARE MET!!!

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:
