Answer:
First, find 20% of the 200 books. Then, subtract that amount by the total and divide that amount by 20 to receive your answer.
Step-by-step explanation:
20 x 200
/100 = 40
Therefore, there are 40 books missing.
200-40 = 160
160/20 = 8 shelves are filled with books.
There are 10 shelves in total: 160 books are on 8 shelves and 40 books are missing for 2 shelves
Around 6 hours (exact decimal would be 5.99865). I did this by multiplying 14.85*40 (getting 594). After that, I subtracted 594 from 727.65 (getting 133.65), then multiplying 14.85 by 1.5, getting 22.28, and then, I did 133.65/22.28, getting 5.99865, which I rounded to 6.
P(5 on one throw) = 1/8
expected number of 5's in 400 throws = 1/8 * 400 = 50
20/24-(-18/24)=38/24
Subtracting a negative is adding a positive.
20/24+18/38
38/24
24 goes into 38 once and 14/24 is left over.
1 14/24
Divide the fraction by two for simplest form.
1 7/12
