A taxi driver records the time required to complete various trips and the distance for each trip. The best fit line is given by the equation $$, where $$ represents the distance in miles, and $$ represents the time for the trip in minutes. Use the best fit line to estimate the distance for a trip that takes 20 minutes.

Complete question :

A taxi driver records the time required to complete various trips and the distance for each trip. The best fit line is given by the equation y = 0.467 x + 0.417 where y represents the distance in miles, and x represents the time for the trip in minutes. Use the best fit line to estimate the distance for a trip that takes 20 minutes.

9.757 miles

Step-by-step explanation:

Given the model Equation:

y = 0.467x + 0.417

y = predicted distance in miles

x = trip time in minutes

The distance for a trip that takes 20 minutes

Substitute 20 for X in the best fit equation

y = 0.467(20) + 0.417

y = 9.34 + 0.417

y = 9.757

Hence, distance in miles for a 20 minutes trip is 9.757 miles

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
