Step-by-step explanation:
<span>Simplifying
3x2 + -6x + c = 0
Reorder the terms:
c + -6x + 3x2 = 0
Solving
c + -6x + 3x2 = 0
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add '6x' to each side of the equation.
c + -6x + 6x + 3x2 = 0 + 6x
Combine like terms: -6x + 6x = 0
c + 0 + 3x2 = 0 + 6x
c + 3x2 = 0 + 6x
Remove the zero:
c + 3x2 = 6x
Add '-3x2' to each side of the equation.
c + 3x2 + -3x2 = 6x + -3x2
Combine like terms: 3x2 + -3x2 = 0
c + 0 = 6x + -3x2
c = 6x + -3x2
Simplifying
c = 6x + -3x<span>2</span></span>
Mean - add up all of the scores, and divide it by the number of members:
68 + 62 + 60 + 64 + 70 + 66 + 72 = 462
462 / 7 = 66
ANSWER: The mean is 66
Median - write out all the numbers in order, and select the middle value:
60, 62, 64, 66, 68, 70, 72
ANSWER: As you can see, 66 is the middle value.
Midrange - find the mean (average) of the smallest and largest number:
Largest number: 72
Smallest number: 60
Midrange: 72 + 60 = 132
132 / 2 = 66
ANSWER: So the midrange is 66
14 because he didn't gather 28 or more he gathered only 14
