Answer:
Step-by-step explanation:
Let the cost of the Uber ride be represented by y in dollars.
Let the number of miles that the Uber rides be represented by x.
The equation relating x and y is expressed as
y = 2/3x + 4.
This is a slope intercept form equation. The slope is 2/3 and it represents the cost per mile.
The cost of a 21 mile ride will be
Substituting x = 21 into the given equation, it becomes
y = 2/3 × 21 + 4 = 14 + 4 = 18
The 21 mile ride costs $18
Part B) The $46 ride will cost
Substituting y = 46 into the given equation, it becomes
46 = 2x/3 + 4 =
46 - 4 = 2x/3
42 = 2x/3
2x = 42 × 3 = 126
x = 126/2 = 63
The $46 ride will be 63 miles

Name Score
Julia 650
Andrew 550
Jason 380
Cathy 720
Jessica 710
Robert 550
Point estimate for the mean score:
Sample mean = sum of all observations / number of observations
sample mean = (650+550+380+720+710+550) / 6
sample mean = 3560 / 6
sample mean = 593.33
The point estimate for the mean score is 593.33
