Answer:

Infant mortality will reduce to 33% in 1.63 years

Step-by-step explanation:

Let the population be X

Population after 1 year

X - 7.3 % of X

X -0.073 X\\0.927X

As we know

P = P_0 * e^{rt}

Substituting the given values we get -

\frac{P_0 - 0.33P_0}{P_0} = e^{-0.33 * t}\\0.67 = e^{-0.33 * t}\\

Taking log on both sides we get -

-0.20273 = -0.33 * t\\t = 1.627

Solve for y:-<br><br> y - 18 = 10<br><br> y = ? <br><br> Thank You!
Simora [160]
In this question we can see that there is one unknown variable named “y” and one equation. So it is absolutely possible to find the correct value of the unknown variable “y”. Now let us check the equation that is given and solve it correctly.
y - 18 = 10
y = 10 + 18
  = 28
So the value of the unknown variable “y” is 28. I hope this is the answer you were looking for and the procedure is clear to you.
