James wants to send two gifts by mail. one package weighs 2 3/4 pounds. one package weighs 2 3/4 pounds. the other package weighs 1 3/4 pounds. what is the total weigh of the package?

4 1/2 pounds

Step-by-step explanation:

To add 2 3/4 and 1 3/4, first add the whole number portions:

2+1 = 3

Next add the fractions.  These two already have a common denominator, so we just add the numerators:

3/4+3/4 = (3+3)/4 = 6/4

This gives us 3 6/4.  This is a mixed number with an improper fraction; we must simplify.

4 goes into 6 one time with 2 left over; this makes it 1 2/4.  This makes our total

3+1 2/4 = 4 2/4 = 4 1/2

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.

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
