Answer:
a. The mean is 123.9
]b. The median is 123.5
c. The modes are 119, 128 an 108
d. The range is 55
e. The variance is 246.341
f. The standard deviation is 15.7
g. The coefficient of variation is 12.672
C. Multiply both sides by 9/5.
C = 5/9(F – 32)
We want to isolate F, which means we need to get F alone.
The quantity in the parentheses is multiplied by 5/9. We need to do the opposite, or multiply by the reciprocal to isolate the parentheses
9/5 C = 9/5* 5/9(F – 32)
9/5 C = F-32
This is the first step in isolating, or solving, for F

Answer:
y = - 2x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 8, 22) and (x₂, y₂ ) = (3, 0)
m = 
= 
= - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (3, 0), then
0 = - 6 + c ⇒ c = 0 + 6 = 6
y = - 2x + 6 ← equation of line
