What is the equation of the trend line in the scatter plot? Use the two blue points to write the equation in slope-intercept form. Write any coefficients as integers, proper fractions, or improper fractions in simplest form.

• y = 2x + 3

• y = 3x + 2

• y = 1/2x + 3

• y = 2/3x + 1

You pick a card, roll a die, and flip a coin. How many outcomes are possible?

• 6

• 12

• 24

• 48

You roll a die, flip a coin, and pick a marble. How many outcomes are possible?

• To find the total number of outcomes, we multiply the number of outcomes for each action. A die has 6 outcomes, a coin has 2 outcomes, and if we assume there are 10 different marbles, then the total outcomes are 6 * 2 * 10 = 120.

• To find the total number of outcomes, we add the number of outcomes for each action. A die has 6 outcomes, a coin has 2 outcomes, and if we assume there are 10 different marbles, then the total outcomes are 6 + 2 + 10 = 18.

• To find the total number of outcomes, we multiply the number of outcomes for each action. A die has 6 outcomes, a coin has 2 outcomes, and if we assume there are 5 different marbles, then the total outcomes are 6 * 2 * 5 = 60.

• To find the total number of outcomes, we multiply the number of outcomes for each action. A die has 6 outcomes, a coin has 2 outcomes, and if we assume there are 8 different marbles, then the total outcomes are 6 * 2 * 8 = 96.
