There are 100 books in the library. There are non-fiction and fiction books. Write the fraction of the books that are fiction.
1 answer:
The complete question in the attached figure
Let
x--------------------- > <span>non-fiction books.------------------ > x=60
y--------------------- > f</span><span>iction books.
we know that
x+y=100
y=100-x=100-60=40
the </span>fiction books. are y=40
if 100%----------------------- > 100 books
X---------------------------- > 40
X=40*100/100=40%
40%-------------- > 40/100=20/50=2/5
the answer is
<span>the fraction of the books that are fiction is (2/5)</span>

Answer:
(a) The amount of ice cream increase as temperature increases
(b)
--- equation
--- y intercept
--- slope
Step-by-step explanation:
Given
See attachment for graph
Solving (a): The relationship between the variables
From the attached graph, the dots on the graph increases towards up-right direction. This implies that there is a positive correlation between the variables.
In other words;
The amount of ice cream increase as temperature increases
Solving (b): The line of best fit
First, we draw a line through the points (the line should have almost equal points on both sides; see attachment 2).
From (2), we select any 2 points on the line:
The slope (m) is:
So, the line of best fit is:
Substitute known values:
The y-intercept is when
So, we have:
