Step-by-step explanation:
Firstly, we'll try to simplify the integrand. By hint 1, we see that:
Simplifying the integrand gives us:
Next, by hint 2, we observe that:
So this tells us to make the substitution: 
Doing so gives us:
, which should be trivial.
5 x 0.2 = 25
Or to put it a different way
25 / 0.2 = 5
Dividing something by a number greater than 1 gives you a smaller number
Dividing something by 1 gives the same number
Dividing something a number smaller than 1 gives you a larger number
Answer:
77 red marbles
Step-by-step explanation:
the bag has R and B marbles
P(B)=1/12 = number of blue /total number of marbles
so 1/12=?/84
in the bag must be 84/12=7 marbles that are blue
84-7=77 red marbles
