Answer:
Yes, it is representative because each type of book was represented in the approximate proportion that exists in the library.
Step-by-step explanation:
Given is a chart, showing the distribution of the number of books in a library.
Also given that Sahira chooses a random sample from the library and records the type of books in the chart below.
Sahira's sample can be said to be representative because given that books are taken at random. So just because literacy books were more we cannot say it is not representative II option is not right, because each book was not chosen uniquely, just random books were drawn
Lastly The Answer is C) Yes, it is representative because each type of book was represented in the approximate proportion that exists in the library is right, because each book selected represents the sample from population of full library books.
105 miles
Explanation
First we need to find the time traveled. I first convert the times into minutes. Use military time if one is am and the other is pm
3:30 - 210 minutes
5:00 - 300 minutes
Now we can subtract the two
300-210= 90
Now we can convert that back into time
1:30
We now know they drove for an hour and 30 minutes, so now lets calculate that.
Knowing that they drove 70mph, that means every hour they drove 70miles. So lets add 70 for every hour
70miles ; 30 minutes
We still have 30 minutes leftover, but we know that 30 minutes is half of an hour. So we can just divide 70 in half.
70÷2= 35
Now we need to add our miles together
70+35= 105miles
2 Gallons = 32 Cups.
32 - 12 (because he served them to his guests)= 20.
20 Cups of soup were left after the party.
