Answer:
If a number is positive, Leila's theory that 75% of a number will always be greater than 50% of another number is true; however, if both numbers are negative, or if the number of which she finds 50% is much greater than the number of which she finds 75%, Leila's theory could be incorrect.
This inequality shows that Leila is correct: 100(0.75) \geq 50(0.50)100(0.75)≥50(0.50) (which simplifies to 75 \geq 2575≥25 )
This inequality shows that Leila is incorrect: 50(0.75) \geq 100(0.50)50(0.75)≥100(0.50) (which simplifies to 37.5 \geq 5037.5≥50 )
Answer:
The houses surveyed had between 1 and 10 rooms ..
Step-by-step explanation:
We can see from the histogram that the minimum number of rooms any house had was 1 and the maximum number of rooms were 10.
Range is the difference between highest and lowest value of a data set.
Hence, the range from the given histogram can be determined as:
The houses surveyed had between 1 and 10 rooms ..
Try it! Suppose the number I'm thinking of is 49.
The product of 49 and 7 is 343; we subtract 3 from that, obtaining 340.
Divide this 340 by 13: 340/13.
Double this quotient: 680/13
680 + 390
Add 30 to this result: 680/13 + 30 = ------------------ = 1070/13
13
Sadly, this is not 50, as we'd hoped.
Why don't you try doing this yourself? Would you do anything differently from the way I did it?

Rose has read more because 3/6 of a book is more then 3/8 of a book in Alexa's book the chapters will be shorter than the chapters in Rose's book.
Hope this helps
