Eric collected 1 1/3 times as many beads as Malik in the beginning. If Eric collected 48 more beads and Malik collected 13 more beads Eric would have twice as many beads as Malik How many beads did they collect all together

At the beginning, Malik had 33 beads, and Eric had 44, making them have 77 beads in total

At the end, Malik had (33 + 13 =) 46 beads and Eric had (44 + 48 = ) 92 beads.

they collected 77 beads all together.

Step-by-step explanation:

Let x represent the number of beads that Eric collected.

Let y represent the number of beads that Malik collected.

Eric collected 1 1/3(4/3) times as many beads as Malik in the beginning. This means that

x = 4y/3

If Eric collected 48 more beads and Malik collected 13 more beads, Eric would have twice as many beads as Malik. This means that

x + 48 = 2(y + 13)

x + 48 = 2y + 26 - - - - - - - - - - -1

Substituting x = 4y/3 into equation 1, it becomes

4y/3 + 48 = 2y + 26

Cross multiplying by 3, it becomes

4y + 144 = 6y + 78

6y - 4y = 144 - 78

2y = 66

y = 66/2 = 33

x = 4y/3 = (4 × 33)/3

x = 44

The total number of beads that they collected is

44 + 33 = 77 beads

12

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
