now, le'ts do the summation using 0.5n+2
(0.5(2.7) + 2)+(0.5(3.0) + 2)+(0.5(3.2) + 2)+(0.5(3.7) + 2)+(0.5(4.4) + 2)+(0.5(4.9) + 2)+(0.5(5.3) + 2)
which gives us 27.6. Now, the paper doesn't state, or at least I don't see it, but that's just the sum of the hours, to get the average we simply divide that by 7, the amount of items, and 27.6 ÷ 7 gives us about 3.94.
does it underestimate or overestimate the one found with the summation? well, the summation gave us 3.9 and 3.94 is just 0.04 or 4 hundredths above it.
Parallel = same slope
y = 3x + b
5 = 3(1) + b, b = 2
Solution: y = 3x + 2
12: 1.57c
13: $70.65
14: $25.65
I believe it is the bottom one, spanning -6 to 6
The absolute value is the distance from the number to 0
The absolute value of 6 is 6 and the absolute value of -6 is 6 because they are both 6 values away from 0
What is that supposed to be 70, 7 or 700
