the word times means to multiply a number the said amount of times for example
cat has 5 sticks. Roger has 2 times as many sticks as cat. the equation is 5 × 2 that would equal 10. :)
<span>There are 100 * 99 = 9900 different ways to choose two students out of 100 bandmembers. You and our brother are 2 of that ways: you being selected first and you being selected second. Therefore the probability that you two are selected is 2 / 9900 = 0,000202. You can also think as the probability of you being selected among 100 bandmembers, which is 1/100, times the probability of your brother being selected among 99 members, which is 1/99 => (1/100) * (1/99) = 1/ (100*99) = 1 / 9900; plus the same for your brother being selected first and you second => [1/9900] * 2 = 2/9900, which is the same calculated above.</span>
Answer:
It will take her 3 hours to read 120 pages.
Step-by-step explanation:
The number of pages read(y) after x hour can be modeled by a linear function in the following format:

In which a is the number of pages read per hour and b is the initial number of pages read.
A straight line goes through (0, 0)
This means that when 
So



(0.5, 20)
When 
So




The function in:

According to the graph, which statement must be true?
It will take her 2 hours to read 60 pages.

Less than 2 hours for 60 pages, so this is false.
It will take her 3 hours to read 120 pages.

This statement is true.
It will take her 4 hours to read 180 pages.

More than 4 hours to read 180 pages. So false.
It will take her 5 hours to read 210 pages.

More than 5 hours to read 210 pages. So false.
