Answer:

The answer is 600 minutes (10 hours)

Step-by-step explanation:

20 minutes = 1 student.

30 students x 20 = 600 minutes

600mins / 60 (because an hour has 60 mins) = 10 hours.

Answer:

it would take around 10 hours to grade all 30 papers

Step-by-step explanation:

if for one student it takes 20 minutes that means you would have to do 20 minutes 30 times which is 600 minutes. to convert that to hours you divide total minutes (600) by 60 which gives you 10 hours. no need for thanks

Team{Number of Students}

Acers{78}

Blazers{80}

Outbacks{83}

Quasars{77}

Voyagers{82}

<u>Total-400</u>

Answer:

(A)81/399

Step-by-step explanation:

The probability that the Principal selects a voyager on the first try is:

82/400

Since another student is to be selected, the <u>total population has reduced by 1 </u>and the <u>number of voyagers likewise has been reduced by 1.</u>

Therefore:

Probability that another voyager is selected on the second try =

81/399

<u>The correct option is A.</u>
