The mean of a set of numbers is the average of the set. To find the mean we must add all the numbers in the set together and divide the sum by how many numbers there are in the set.
95 + 78 + 84 + 86 + 89 + 64 = 496
499 / 6 = 82.67
The mean is 82.67.
The mode of a set of numbers is a number that shows up the most in the set. All the numbers in this set appear once, so, there is no mode.
The median of a set of numbers is the number that is in the very middle of the set. Since the middle has two numbers in it we will find the mean of the two of them.
84 + 86 = 170
170 / 2 = 85
85 is median.
To find the range we need to subtract the smallest number by the largest number.
95 - 64 = 31
31 is the range.
I hope this helps. :)
Answer:
y=-8x+12
Step-by-step explanation:
8 is you m and 12 is your b
What you do is get into the form
(x-h)^2+(y-k)^2=r^2
(h,k) is center
r=radis
complete the square with x and y
x^2+y^2-2x+4y-11=0
group x and y terms together
(x^2-2x)+(y^2+4y)-11=0
take 1/2 of linear coefieicnt and add postive and negative
for x^2-2x, -2/2=-1, (-1)^2=1
for y^2+4y, 4/2=2, 2^2=4
(x^2-2x+1-1)+(y^2+4y+4-4)-11=0
complete the square
(x-1)^2-1+(y+2)^2-4-11=0
add like terms
(x-1)^2+(y+2)^2-16=0
add 16 both side
(x-1)^2+(y+2)^2=16
(x-(1))^2+(y-(-2))^2=4^2
(x-h)^2+(y-k)^2=r^2
(h,k)
(1,-2)
r=4
center is (1,-2)
radius is 4 units
