Try using this app called Calculator Soup, but even tho the name isn’t quite common that doesn’t matter
The average distance between the variable scores and the mean in a set of data is the standard deviation.
The answer is B.
Running burns the most calories folwed by aerobic
so max out the most and min the least
most running
running has no limit, so see least
aerobic, aerobic has to be at most 30 (less than 30)
rowing has to be at least 15 mins
say row=15 mins
then you have 45 mins left
max out on running (minus 1 tho to do running)
so
44mins running 1 min run, 15min row
total calories=507 calories burned
the way to do it is
x=running minutes
y=aerobic minutes
z=rowing minutes
x+y+z=60
9x+6y+7z=max calories
x≥5
y≤30
z≥15
those are the equations
not sure what the objective function is
