The answer is 3.125%.
The relation between number of half-lives (n) and amount of sample that remained (x) can be expressed as:

It is given:
n = 5
To find x, we will change n in the equation with five:
<span>

</span>⇒ <span>

</span>⇒ <span>

</span>⇒

Therefore, 3.125% of a radioactive species <span>would be found as daughter material after five half-lives.</span>
Answer:

Taking the change in y over the change in x. Then the correct option is A.
<h3>What is the equation of a line passing through two points?</h3>
Suppose the given points are (x₁, y₁) and (x₂, y₂), then the equation of the straight line joining both two points is given by
![\rm (y - y_1) = \left [ \dfrac{y_2 - y_1}{x_2 - x_1} \right ] (x -x_1)](https://tex.z-dn.net/?f=%5Crm%20%28y%20-%20y_1%29%20%3D%20%5Cleft%20%5B%20%5Cdfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D%20%5Cright%20%5D%20%28x%20-x_1%29)
The equation of the line can be determined by the two known points.
Taking the change in y over the change in x.
Then the correct option is A.
