Answer:
1.25 pages per minute
Step-by-step explanation:
If Sydney read 50 pages at a constant rate in 40 minutes, then to get pages per minute just divide total pages by minutes
The probability is 0.2743.
Calculating the z-score for this time, we have:
z = (X-μ)/σ
z = (96-90)/10 = 6/10 = 0.6
Using a z-table (http://www.z-table.com) we see that the area to the left of this, less than this score, is 0.7257. This means the area greater than this would be 1-0.7257 = 0.2743.
You multiply fractions simply by multiplying numerators and denominators with each other:
The quotient is the answer to a division problem.
