The cost of having a package delivered has a base fee of $10.80. every pound over 5 lbs cost an additional $0.41 per pound. write an equation that expresses the cost c in terms of w, the total weight in pounds of a package weighing over 5 lbs. a. c = 10.8w + 0.41 c. c = 0.41(w - 5) + 10.8 b. c = 0.41w + 10.8 d. c = 0.41w + 12.85

c. C = 0.41(w - 5) + 10.8

(w - 5) will represent the number of pounds over 5. For example, for a weight of 6 pounds, 6-5 = 1 is the number of pounds over 5.

The cost is $0.41 for each pound over 5, so that cost can be represented by ...

... 0.41(w - 5)

This charge is in addition to the base charge of $10.80, so the total cost will be ...

... C = 0.41(w - 5) + 10.80

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
