Answer:
The total number of marbles in the bag is 50.
Step-by-step explanation:
Here, we have n trials, without replacement. So the hypergeometric distribution is used.
The mean of the hypergeometric distribution is:
In which n is the number of items in the sample, k is the number of items in the population that are classified a success and N is the size of the population.
15 marbles are drawn:
This means that
A bag contains some number of marbles. It is known that 20 of them are red.
This means that , since a success is drawing a red marble.
Assuming E(X)=6 red, what is the total number of marbles in the bag?
We have to find N when
So
The total number of marbles in the bag is 50.
Answer:
The maximum height is the y-value of the vertex.
h(t) = -4.9t² + 20t + 65
a=-4.9 b=20 c=65
h(2) = -4.9(2)² + 20(2) + 65
= -19.6 + 40 + 65
= 85.4
