Answer: Choice C)
--------------------------------------
mean = xbar = (2400+1750+1900+2500+2250+2100)/6
mean = 2150
Subtract the data values from the mean to get
2400-2150 = 250
1750-2150 = -400
1900-2150 = -250
2500-2150 = 350
2250-2150 = 100
2100-2150 = -50
The differences are: 250, -400, -250, 350, 100, -50
Then you square those values and add up the squares
(250)^2 + (-400)^2 + (-250)^2 + (350)^2 + (100)^2 + (-50)^2 = 420,000

Answer:
Red
Step-by-step explanation:
P = 30/120 = 1/4
The spinner is divided into 8 equal sections. 1/4 of 8 is 2. So we're looking for a color that appears on exactly 2 of the sections.
The color is red.
*the table being referred to is attached below
Answer:
The table does not show a proportional relationship between variable g and h.
Step-by-step explanation:
For a proportional relationship to exist between two variables, there must be a constant, of which serves like a unit rate, when comparing two variables.
Thus, in the table attached below, there is no obvious constant of proportionality between variable g and variable h.
Thus, 
≠ 
≠ 
Parallel lines need to have same slope
The lines have different slopes
It is false.
