Answer:
Step-by-step explanation:
Let the 3 numbers be 4x , 5x and 6x
4x + 6x = 5x + 55
10x = 5x + 55 Subtract 5x from both sides.
<u> 5x 5x</u>
5x = 55 Divide by 5
x = 55/5
x = 11
Therefore the numbers are
3*11 = 33
4*11 = 44
5*11 = 55
It shows a positive correlation
Just go from the very left of the graph to the very right and see, if the points go up or down.
Or pick off some points to see the trend
(2,1) (3,2) and (5,4)
These points show that over time the number of typos go up with the number of pages printed.
96.2857143 would be the answer because you add all the numbers together then divided by 7
