Answer:

Range = 24

Step-by-step explanation:

Record of percentage

59, 61, 83, 67, 81, 80, 81

We need to find the range

To find the range , we order the numbers from smallest to largest.

Then Subtract the smallest number from largest number.

When we arrange the numbers it becomes

59, 61, 67, 80, 81, 81, 83

Smallest number is 59 and largest number is 83

Range = 83 - 59 =24

!!MATH GENIUSES HELP ME!!

Answer:

Step-by-step explanation:

Let x be Bill’s scores.

Let y be Theo’s scores.

x + y = 90

x² = y

Solve for x in the second equation.

x = √y

Put x as √y in the first equation and solve for y.

√y + y = 90

√y = 90 - y

y = (90 - y)²

y = - y² - 180y - 8100

0 = -y² - 181y - 8100

0 = (-y+81)(y-100)

-y+81=0

y = 81

y - 100 = 0

y = 100

100 does not work if we plug in to check, so y is 81.

y = 81

Put y as 81 in the first equation and solve for x.

x + 81 = 90

x = 9

Bill scored 9 goals and Theo scored 81.
