Vanessa is a caterer. she made several batches of appetizers last weekend for an event. this weekend, vanessa made 4 times as many batches. she made a total of 25 batches of appetizers for the two weekends. determine the number of batches vanessa made last weekend and the number of batches she made this weekend. let b= the number of batches of appetizers vanessa made last weekend.

100 x 13/16 x 25b =4

18 3/4 = 25b/4

b=25/4

b= 6.25

Step-by-step explanation:

25/4 = 6 1/4 last weekend and 18 3/4 this weekend.

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.
