There are 2 ways to turn a number into a percent...
(1) move the decimal 2 spaces to the right....0.3 = 30%
(2) multiply by 100....0.3 x 100 = 30%
The answer is D. There is a one third change the book will be an adventure book because there are 10 adventure books and 30 books altogether. 10 / 30 = 1/3
Answer:
Option A is correct
A. Neither
Step-by-step explanation:
Given:
Two points are given (2, 15) and (0, 5)
Let
and ![(x_{2}, y_{2})=(0,5)](https://tex.z-dn.net/?f=%28x_%7B2%7D%2C%20y_%7B2%7D%29%3D%280%2C5%29)
The slope of the line ![m=\frac{y_{2}- y_{1}}{x_{2}- x_{1}}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_%7B2%7D-%20y_%7B1%7D%7D%7Bx_%7B2%7D-%20x_%7B1%7D%7D)
Put all known value in above equation.
![m=\frac{5- 15}{0- 2}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B5-%2015%7D%7B0-%202%7D)
![m=\frac{-10}{-2}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-10%7D%7B-2%7D)
![m=5](https://tex.z-dn.net/?f=m%3D5)
So the slope of the line
.
The equation of the is
-------------------(1)
Where m is the slope of the line and b is y-intercept of the line.
Take point (0, 5) to compute the value of b.
Put
in equation 1.
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
![5=5(0)+b](https://tex.z-dn.net/?f=5%3D5%280%29%2Bb)
![5=0+b](https://tex.z-dn.net/?f=5%3D0%2Bb)
![b=5](https://tex.z-dn.net/?f=b%3D5)
Take point (2, 15) to compute the value of b.
Put
in equation 1.
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
![15=5(2)+b](https://tex.z-dn.net/?f=15%3D5%282%29%2Bb)
![15=10+b](https://tex.z-dn.net/?f=15%3D10%2Bb)
![15-10=b](https://tex.z-dn.net/?f=15-10%3Db)
![b=5](https://tex.z-dn.net/?f=b%3D5)
So the equation of the line is.
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Put m and b value in above equation.
------------(2)
![5x-y=-5](https://tex.z-dn.net/?f=5x-y%3D-5)
add 10 both side in equation 2.
![y+10=5x+5+10](https://tex.z-dn.net/?f=y%2B10%3D5x%2B5%2B10)
![y+10=5x+15](https://tex.z-dn.net/?f=y%2B10%3D5x%2B15)
![y+10=5(x+3)](https://tex.z-dn.net/?f=y%2B10%3D5%28x%2B3%29)
So the equation of line that passes through the point (2,15) and (0,5) is.
or
or ![y+10=5(x+3)](https://tex.z-dn.net/?f=y%2B10%3D5%28x%2B3%29)
Therefore, Neither the following equations represents a line that passes through the points (2,15) and (0,5).
Seventeen-thousand and one hundred 6 thousandths written in standard form would be 17,000.106
