Afootball team has attempted 6 running plays. the change in field position resulting from each play is shown in the table. running play outcomes play 1 –3 yards play 2 2 yards play 3 –1 yard play 4 –2 yards play 5 –3 yards play 6 1 yard what is the average change in field position per running play? –6 yards per play –1 yard per play 0 yards per play 1 yard per play

-1 yard per play

Step-by-step explanation:

The average of a data set is given by :-

Given: The total number of plays =6

Sum of the change in field position resulting from each play is given by :-

Now, the average change in field position per running play is given by :-

Hence, the average change in field position per running play is -1 yard per play.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

the diver is 33 feet below the surface.

step-by-step explanation:
