The ratio of North American Butterflies to South American butterflies at a butterfly park is 6:4. The ratio of South American butterflies to European butterflies is 4:3. There are 72 North American butterflies at the butterfly park. Part 1 out of 2
How many South American butterflies are there?

There are*blank* South American butterflies.

48 South American butterflies

Step-by-step explanation:

Since the ratio of American butterflies to South American butterflies is 6:4, the unit rate for every North American butterfly would be 2/3. In total, there are 72 North American butterflies meaning you would have to multiply 2/3 by 72, which would equal to 48.

Ratio of N to S is 1:2/3

72 times 1 equals 72 so you would multiply 72 by 2/3 and you would get 48.

step-by-step explanation:

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

non hispanic white population

non hispanic white males

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
