Answer with explanation:
Time taken by a person to read number of pages in a chapter= 18 minutes
It is not given what is the length of the page.So,we can't say exactly how many pages can a person read by completely understading what is written in each page in a chapter.
So, to fully understand each and every page in 18 minutes you can read minimum number of pages from the option given.
Option A:⇒ 15, is most appropriate.
Using the equation that models the linear function, the best prediction is: D. 21.
What is the Equation of a Linear Function?
The equation that models a linear function is given as y = mx + b, which can be used to make predictions for the relationship between two variables, x and y.
Given the equation of the model as, y = 0.86x - 0.09:
- x = number of pages
- y = time spent reading
Plug in y = 18 into the equation to find x (number of pages):
18 = 0.86x - 0.09
18 + 0.09 = 0.86x
18.09 = 0.86x
18.09/0.86 = x
x ≈ 21.
Best prediction is: D. 21.
