45mins ÷ 15pages = 3
so she reads 3pages per minute

Answer:
Relative Frequency Method
Step-by-step explanation:
If I carry out an experiment involving 25 throws of a coin and I obtain 13 Heads(H), the Relative Frequency of obtaining Heads will be 13/25.
Now if I intend to find out approximately how many Heads will
occur in 300 throws, I simply use the result or experimentation data that I have.
This is done below:
Relative Frequency of Obtaining a Head= 13/25 =0.52
Number of Heads obtained in 300 throws
= Relative Frequency X Number of Trials
=0.52 X 300
=156
This is an example of how relative frequency method works.
Answer:
x = -9
Step-by-step explanation:
Let unknown number = x
Largest 2-digit number = 99
x * (-11) = 99
x = 99 ÷ (-11)
x = -9
