What you can say is:

2 choices for the first one (metals)

5 choices for the second choice stemming off of all the possible first choices (gems)

2 choices stemming off of all those combinations (shape)

So basically it would be:

2 * 5 * 2 

Which is equal to 20.

What is the equation of this line in slope-intercept form?
Anna11 [10]

Answer:

<em>y = -3x + 2</em>

Step-by-step explanation:

From the graph, you see the line intersects the y-axis at y = 2, so the y-intercept is b = 2.

Now we need the slope. We need to find the number of vertical and horizontal units to go from one point to the other. Starting at point (-1, 5), go down 6 units and then go right 2 units. The change in y is -6. The change in x is 2. slope = m = (change in y)/(change in x) = -6/2 = -3.

m = -3; b = 2

y = mx + b

y = -3x + 2

A number cube with faces labeled from 1 to 6 will be rolled once.
kramer

Answer:

\Omega=\{1,2,3,4,5,6\}

A=\{1,2,3,4\}

Step-by-step explanation:

<u>Sample Space</u>

The sample space of a random experience is a set of all the possible outcomes of that experience. It's usually denoted by the letter \Omega.

We have a number cube with all faces labeled from 1 to 6. That cube is to be rolled once. The visible number shown in the cube is recorded as the outcome. The possible outcomes are listed as the sample space below:

\Omega=\{1,2,3,4,5,6\}

Now we are required to give the outcomes for the event of rolling a number less than 5. Let's call A to such event. The set of possible outcomes for A has all the numbers from 1 to 4 as follows

A=\{1,2,3,4\}
