The graph below shows the numbers of cups of apple juice that are mixed with different numbers of cups of lemon-lime soda to make servings of apple soda: A graph is shown. The values on the x axis are 0, 1, 2, 3, 4, 5. The values on the y axis are 0, 6, 12, 18, 24, 30. Points are shown on ordered pairs 0, 0 and 1, 6 and 2, 12 and 3, 18 and 4, 24. These points are connected by a line. The label on the x axis is Lemon -Lime Soda in cups. The title on the y axis is Apple Juice in cups. What is the ratio of the number of cups of apple juice to the number of cups of lemon-lime soda? 1:24 24:1 1:6 6:1

Answers

The ratio of the number of cups of apple juice to the number of cups of lemon-lime soda is 6:1

What is the ratio?

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

Given that x axis denotes Lemon lime soda in cups and y axis denotes Apple juice in cups

(x) Lemon -Lime Soda ; 0, 1, 2, 3, 4, 5

(y) Apple Juice : 0, 6, 12, 18, 24, 30

Therefore, the ratio can be written as;

the number of cups of apple juice : the number of cups of lemon-lime soda

6 : 1

Then, ratio is 6:1

Hence, the ratio of the number of cups of apple juice to the number of cups of lemon-lime soda is 6:1

A bag contains some number of marbles. It is known that 20 of them are red. When 15 marbles are drawn, without replacement, we get 6 red. Assuming E(X)=6 red, what is the total number of marbles in the bag?

Answers

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:

$E(X) = (n*k)/(N)$

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 $n = 15$
