Amari is selling a pack of 5 cookies for $4.85.Which scale factor could be used to calculate the cost for 45 cookies? A.1/5
B.43.65
C.9
D.5

B

Step-by-step explanation:

would divide 4.85÷5=.97 then .97×45 to get ur answer hope it helps.

The correct answer is C: 9

Step-by-step explanation:

there are 5 cookies per box and if you divide 45 by 5 you get the end result of 9 boxes

the same goes if you multiply 5 and 9 because you still get the answer of 45

and this might be unnecessarry but if u want the price for all of it the answer is $43.65

have a nice day!

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.
