Answer:
Mean = sum of all observed values / sum of frequency
Mean= (1*2 +2*2 + 3*2 + 4*1 + 5*2 + 6*1) / (2+2+2+1+2+1)
Mean = 32 / 10
Mean = 3.2
Answer: Y=54x + 60
Step-by-step explanation:
You add both project fees together ( 35 + 25 = 60) then you add together the hourly rates (20 + 34 = 54) and the hourly rate is your slope because it’s per hour and the 60 is your y intercept because it’s paid upfront.
(5,0) is the x-intercept because when you plug 0 in for y, x=5.
(0,4) is the y-intercept because when you plug in 0 for x, y=4.
