Answer 1

121500 twins birth

Explanations:

In order to determine the number of birth in 2000, we will use the expressionn as shown:

`P(t)=(100+14)\%\text{ of x}=\text{138,510. }`

Note that the total percent of twins birth initially is 100%

x is the approximate twin births in 2000.

Simplify the result to determine the value of x

`\begin{gathered} 114\%\text{ }of\text{ x}=138,510 \\ 1.14x=138,510 \end{gathered}`

Divide both sides by 1.14

`\begin{gathered} (1.14x)/(1.14)=(138510)/(1.14) \\ x=121500 \end{gathered}`

Hence the total number of twin birth in 2000 were approximately 121500 twins birth
