The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). the mean maximum oxygen uptake for elite athletes has been found to be 60 with a standard deviation of 7.2. assume that the distribution is approximately normal.

The larger of two number is 4 less than twice the smaller number. the sum is 41. find the numbers

Can someone check if i did this correct. it’s number 4 if you’re wondering.
