Which graph shows the line of best fit for the data?

Which graph shows the line of best fit for the data?

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.
