Can I have brainliest?
b) c = b3.99 + 4.95
c is the total cost, 4.95 is a constant fee that you have to pay for the monthly service, so that will always be there. b3.99 will vary depending on how many books are downloaded.
c) I can't really graph now I'm sorry, I don't know if this graph should be accurate or not but If you want it very accurate then you're gonna have a y-intercept (x = 0) at 4.95 And you're gonna wanna go up 3.99 units each x unit, so at (x=1) you must be at y= 4.95 + 3.99 = 8.94
If you don't want it extremely accurate then you can just make the y-intercept at 5 and you can go up 4 units each x unit.
Answer:
a. Use the regression equation
Step-by-step explanation:
Given
See attachment for missing part of question
Required
What can be used to predict diameter, given family income
We can see (by observation) that the data on the table can only be represented on a scattered plot, and scattered plot uses regression equation for data prediction.
i.e. --- equation of line of best fit
In this case;
<em>When the x value (income) is known, we can simply plug in the value in the above equation to get the y value (diameter)</em>

(hope it helps i plz have brainlist :D hehe)
step-by-step explanation:
Each page from 10 to 99, inclusive (so total of 90 pages) needs two digits (for example page 12 needs two digits: 1 and 2); Each page from 100 to 200, inclusive (so total of 101 pages) needs three digits (for example page 123 needs three digits: 1, 2 and 3)
