The rental rate for a hedge trimmer has a one time fee of $20 plus $30 for each day of the rental. the graph shows points representing the total cost of the rental. a function graph of a ray with three points (0,20), (2,80) and (3, 110) with an x axis of zero to five days and a y axis of zero to one hundred forty in total cost which linear equation, in slope-intercept form, that models the total cost of the rental over time? y = 2x + 80 y = 20x + 30 y = 30x + 20 y = 30x y = 20x

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
