Answer:
Mean = (19 + 20 + 21 + 22 + 23)/5 = 105/5 = 21
x x - mean (x - mean)^2
19 -2 4
20 -1 1
21 0 0
22 1 1
23 2 4
Sum = 10

Answer:
This is a bit confusing for me but here we go.
1x110
10x11 and
i don't really know the third
Step-by-step explanation:
X=7 and x+1=8 are two consecutive integers.
(420,104)(720,164)
slope = (164 - 104) / (720 - 420) = 60/300 = 1/5
y = mx + b
slope(m) = 1/5
(420,104)...x = 420 and y = 104
now we sub and find b, the y int
104 = 1/5(420) + b
104 = 84 + b
104 - 84 = b
20 = b
so ur equation is : y = 1/5x + 20
