you and your business partner track the numbers of customers served and the amount of tips collected per day. the data you gathered is displayed in the chart below.

servers' collected tips
customers- 54 46 34 67 52 22 49 64 55 80 38 42
tips($)- $92 $80 $76 $121 $109 $43 $87 $114 $99 $174 $88 $91

b) find the equation of the trend line(line of best fit). show your work.

c) predict the amount of tips that would be collected if 100 customers were served at the restaurant on a given day. ex[plain your reasoning.

d) explain how to use the regression calculator to make a reasonable prediction given a data table.

( b, c,d are different questions and not options)

maybe - definition of supplementary angles. im not sure. sorry

step-by-step explanation:

y=mx+

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
