Greg’s puppy chewed 1 ⅘ bones in 6 days. What part of a bone did he chew in one day?

3/10 of a bone per day

Step-by-step explanation:

Take the number of bones and divide by the number of days

1 4/5 ÷ 6

Change to an improper fraction

9/5 ÷6

Copy dot flip

9/5 * 1/6

Rewriting

9/6 *1/5

Simplifying the first fraction

3/2 *1/5

3/10

3/10 of a bone per day

3/10

Step-by-step explanation:

1⅘ : 6

X : 1

1.8/6 = X/1

X = 0.3 = 3/10

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.
