Jayden was excited to get his test back for his parents to sign He scored a 105%. He
received the extra 5 points for showing his work.
Which decimal represents his test score?

1.05

Step-by-step explanation:

100% is 1.0, therefore 105% will be 1.05.

Explanation:

Think of 105% as 105.0%

Now remove the percent sign to get 105.0

Lastly, move the decimal point two spots to the left to get to 1.05

Percentages that are over 100% convert to decimal values larger than 1; on the flip side, percentages that are under 100% are between 0 and 1.

More Examples:

76% = 0.76

18% = 0.18

255% = 2.55

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.
