Answer:
46
Step-by-step explanation:
So, we have these values:
40: 1 time
41: 2 times
45: 1 time
48: 2 times
49: 3 times
50: 1 time
A total of 10 dots spread over 6 values.
We need to calculate a weighted mean (average) for them... so, we add up each dot then divide the total by 10:
40 + 41 + 41 + 45 + 48 + 48 + 49 + 49 + 49 + 50 = 460
460 / 10 = 46

No, because there isn't a pattern in the numbers. For the y you are adding one but for the x there isn't a shown pattern. Also when graphing the table, it doesn't make a straight line.
Step-by-step explanation:
For example, look at the table shown. On the x you are adding 1 and for the y you are adding 2. This makes it a function and creates a straight line
Use the substitution method for x
y= 2(2)+5
y=9
