Answer 1

Answer:

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

$\begin{gathered} \frac{1.14x}{1.14}=\frac{138510}{1.14} \\ x=121500 \end{gathered}$

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