Plant fertilizers are categorized by the percentage of nitrogen (N), phosphorous (P), and potassium (K) they contain, by weight. For example, a fertilizer that has N-P-K numbers of 8-5-5 has 8% nitrogen, 5% phosphorous, and 5% potassium by weight. Suppose that a fertilizer has four times as much potassium by
weight as phosphorous. The percentage of nitrogen equals the sum of percentages of phosphorous and potassium. If nitrogen, phosphorous, and potassium
make up 30% of the fertilizer, determine the proper N-P-K label on the fertilizer

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

answer: it is a.,b.,d.
