What survival rate in the 10th year would make the average rate of loss over the 10-year period equal to 38.0%?

The answer is "63%"

Step-by-step explanation:

please find the complete question in the attached file.

Time= 10 year =38.0%

let,  

x=rate

The rate of survival differs from the rate of loss, meaning the rate of survival were:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
