What is the value of x if a e equals x plus 2 mm, e b equals 8 mm, c e equals 3 x mm, and e d equals 4 mm? circle with center q has points a, d, b and c on the perimeter. line segment c d crosses line segment a b at point e.

  x = 4

Step-by-step explanation:

The product of the lengths of the segments of each chord is the same.

  AE·EB = CE·ED

  (x+2)(8) = (3x)(4) . . . . . substitute the given lengths

  8x +16 = 12x . . . . . . . . simplify

  16 = 4x . . . . . . . . . . . . . subtract 8x

  4 = x . . . . . . . . . . . . . . . divide by 4

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
