Ataxi service charges an initial fee of $2.15 then charges $1.68 a mile. write a linear equation to model this situation. a. y = 1.68x + 2.15b. y = 2.15x + 1.68c. c = 1.68x + 2.15yd. c = 2.15x + 1.68y

Initial charge = $2.15

Let  'x' represent the number of miles taxi service charges and the total charges be 'y'.

Charges per mile = $1.68

So charges for x miles =

Total charges = Charges in x miles + initial charges

y = + 2.15

So the answer is option A

Let y represent the total amount charged by the taxi service.

Total charge = fixed charge + variable charge

Given initial fee( fixed charge) =   2.15

Let the taxi travels x miles

Since the rate is $1.68 per mile so if the taxi travels x miles ,then  

the amount incurred =  1.68x

y= 1.68x + 2.15

Hence option A is the correct answer.

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
