Q:

In one country during one year, 804665 women gave birth. Of these women, 3738 gave birth to identical twins. Use these data to estimate how many women, out of a group of 1000 pregnant women, you might expect to give birth to identical twins. Choose the two correct options below. Select one or more: 0 The expected number of women is 5. o The expected number of women is 46. The expected number of women is 465. The calculation is 3738 x 1000 800927 3738 x 1000 804665 The calculation is

Accepted Solution

A:
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 - 804,665x Β  - Β 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.
