Answer:
The expected number of women expected to give birth to identical twins is 5.
The calculation is:
[tex]x = \frac{3738*1,000}{804,665}[/tex]
Step-by-step explanation:
This is a proportionality problem, that can be solved by a rule of three. Here, the measures(the number of women that gave birth to identical twins and the nuber of women that gave birth) are directly related. It means that we have a direct rule of three(cross multiplication).
The problem states that of the 804,665 women that gave birth, 3,738 gave birth to identical twins. It asks of 1,000 women, how many are expected to give birth to identical twins? So, 3,738 of 804665 is how much of 1,000?
3,738 - 804,665
x - 1,000
[tex]804,665x = 3738*1,000[/tex]
[tex]x = \frac{3738*1,000}{804,665}[/tex]
[tex]x = 4.64[/tex]
Rounding up, the expected number of women expected to give birth to identical twins is 5.
