z1×z2=−5√3−5i

Step-by-step explanation:

If we have two complex numbers z 1 = r 1 ( cos α + i sin α ) and z 2 = r 2 ( cos β + i sin β )

z1×z2=r1r2(cosαcosβ+icosαsinβ+isinαcosβ+i2sinαsinβ)orz1×z2=r1r2((cosαcosβ−sinαsinβ)+i(cosαsinβ+sinαcosβ)

or z 1 × z 2 = r 1 r 2 ( cos ( α + β ) + i sin ( α + β ) ) Here we have z 1 = 2 ( cos ( 5 π 6 ) + i sin ( 5 π 6 ) ) and z 2 = 5 ( cos ( π 3 ) + i sin ( π 3 ) and z 1 × z 2 = 2 × 5 ( cos ( 5 π 6 + π 3 ) + i sin ( 5 π 6 + π 3 ) ) = 10 ( cos ( 7 π 6 ) + i sin ( 7 π 6 ) ) = 10 ( cos ( π + π 6 ) + i sin ( π + π 6 ) ) = 10 ( − cos ( π 6 ) − i sin ( π 6 ) ) = − 10 ( √ 3 2 + i 2 ) = − 5 √ 3 − 5 i

P.S My caculations might be off, so  i hope it helps at least.

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
