Answer:
C
Step-by-step explanation:
3/5-1/5=2/5 is the correct answer.
All there ages is 24 all together because if you divide 72/3 you get 24 then multiply it by 3 you will get 72
The expected value is given by:
E(x)= ∑x*p(x)
thus the expected value of calories will be given by:
E(x)=1/6*60+1/2*42+1/3*90
E(x)=10+21+30
E(x)=61
the answer is 61
X^3 / X^5 = X^ -2
you have to subtract the exponents when you’re dividing
