Answer:
M(t) = 4/3 * pi * (4t + 3)^3
Step-by-step explanation:
W(t) = radius after t seconds,
Substitute W(t) for r in V(r)
Since W(t) = 4t +3:
M(t) = 4/3 * pi * (4t+3)^3
Well you only do that when you are in the ones place and you have to regroup a 1in the tens place if you go past 19 then you are going to have to regroup a 2
So first add all of the marbles together: 3+2+6+9=20
Because there are 20 marbles together, that would be your denominator.
All of the other numbers would be your numerator. So you would have:
3/20 green marbles
2/20 yellow marbles
6/20 blue marbles
9/20 red marbles
So your answer would be the probability of picking a red marble from the bag is 9/20 or 45%
There are 19+2+4=25 women
There are 1+9+5=15 men
there are 25+15=40 people
P=25/40=0,625
The answer is D
