The probability that Andrew has heart disease is 0.9. Andrew takes a test for the disease that has an accuracy rate of 75%. What is the probability that Andrew has heart disease and the test accurately predicts it?

The probability that Andrew has heart disease =0.9

Also we know that the accuracy rate of test $=75\%$ or 0.75

The given two events are independent.

Therefore, the probability that Andrew has heart disease and the test accurately predicts it $=0.9 \times 0.75 =0.675$

Mathematics

f(g(x))=18x^3+1

Step-by-step explanation:

Since we have given that

$f(x)=9x^2+1\\\\and\\\\g(x)=\sqrt{2x^3}$

We need to find the f(g(x)).

Here, f(x) denotes the amount of money that she earns per loaf and x is the number of loaves she makes,

and,

g(x) denotes the number of bread loaves she bakes per hour and x is the number of hours she works.

So, our composition would be

$f(g(x))=f(\sqrt{2x^3}))=9(\sqrt{2x^3})^2+1=18x^3+1$

Hence, f(g(x))=18x^3+1
