Answers:

21.75

1.37

10

15

Step-by-step:

Dozen flyers:price

4:7.25

12:x

To solve this mulitply 7.25 by 3 (because this is what we multiplied 4 by to get 12) 7.25*3=21.75

Question 2:

We can write teh following equation

.49+.22(x-1)=price

This is essentially saying that we pay .49 for the first ounce and .22 for every ounce after that

We can plug in an x value to get

.49+.22(5-1)

.49+.22(4)

.49+.88

1.37

Question 3:

We can write the following equation

x+2=y

We need to find out what happens when x=8

8+2=10

Question 4:

We can solve this with ratios

x:y

1.5:4.5

5:x

To solve just multiply 4.5 by 10/3 and get 15

We can just multiply

1. 7.25/4=1.8125 so 1.8125x12=21.75

2. 0.49+(0.22x4)=1.37

3. rule is x+2=y so x=8 then y=10

4.rule is 3(x)=y so x=5 then y=15

i found the life tables for the year 2012. 

life table of males at age 30. probability of dying between ages x and x+1

total population:  

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

males:  

29–30 . . . . . . . . . . . . 0.001420

30–31 . . . . . . . . . . . . 0.001448

white population

29–30 . . . . . . . . . . . . 0.001005

30–31 . . . . . . . . . . . . 0.001037

white males

29–30 . . . . . . . . . . . . 0.001372

30–31 . . . . . . . . . . . . 0.001399

non hispanic white population

29–30 . . . . . . . . . . . . 0.001083

30–31 . . . . . . . . . . . . 0.001116

non hispanic white males

29–30 . . . . . . . . . . . . 0.001477

30–31 . . . . . . . . . . . . 0.001503

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

step-by-step explanation:

the answer is 128
