Fast-Food Bills for Drive-Thru Customers A random sample of 42 cars in the drive-thru of a popular fast food restaurant
revealed an average bill of $16.14 per car. The population standard deviation is $4.83. Estimate the mean bill for all cars from the
drive-thru with 93% confidence. Use a graphing calculator and round the answers to at least two decimal places.

you should at least use a calculater

step-by-step explanation:

step-by-step explanation:

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.
