Suppose you choose a marble from a bag containing 3 red marbles, 3 white marbles, and 5 blue marbles. You return the first marble to the bag and then choose again. Find P(red and blue).

Answers

The answer is 15/121.

Since we have red AND blue, that means that both of these events occur, so we will use the multiplication rule and multiply these two probabilities:

- A probability of choosing a red marble: 3/11. (because there are 3 marbles out of total 11 marbles)
- A probability of choosing a blue marble after the red one: 5/11. (because there are 3 marbles out of total 11 marbles; there are 11 in total again because the first marble has been returned)

So, P(red and blue) is 3/11 * 5/11 = (3*5)/(11*11) = 15/121

which has more volume a cube of sides measuring 4 units each or a sphere with a radius of 3 units

Answers

V cube = 4^3 = 64 $cm^(3)$
V sphere = 4*π*3^3/3 = 4*π*9 = 36*π≈113 $cm^(3)$
V sphere > V cube.

What is equation modelling? What is a mathematical equation and expression?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.

A mathematical equation is used to equate two expressions.

Given is that on Sunday, a local hamburger shop sold a combined total of 428 hamburgers and cheeseburgers. The number of cheese burgers sold was three times the number of hamburgers sold.

Assume that the number of hamburgers sold are [x]. Then, the number of cheese burgers sold will be [3x]. Then, we can write -

x + 3x = 428

4x = 428

x = 17

Therefore, the total number of hamburgerssold were 17.

#SPJ2

The equation you can use is x + 3x = 428 with x as the number of cheeseburgers and 3x the number of hamburgers
you solve for x and get 4x= 428 and x=107

so 321 hamburgers were sold that day.

Complete the missing value in the solution to the equation.

What would be the probability that randomly choosing 3 states from the top 6 murder states would actually be the top 3 states for murders in the United States in the exact correct descending order?
Each state and # of murders
1.California 1790
2.Texas 1089
3.New York 774
4.Pennsylvania 636
5.Michigan 613
6.Georgia 522

Answers

The chances would be (if you cant get duplicates)

1/6

1/5

1/4

If you want the states in order

You multiply them together

6 x 5 x 4 = 1/120 chance to get them in that order
