The y int is where the line crosses the y axis ...so ur y int is 3 or (0,3).
ur slope...start at the y int (0,3)....and if u come down 3, and go to the right 2, and down 3, and to the right 2 u are landing on ur line. So ur slope is -3/2
Answer:
33.9 million miles.
Step-by-step explanation:
We have been given that the number of species of coastal dune plants in Australia decreases as the latitude, in °s, increases.
Further we know that there are 34 species at 11°s and 26 species at 44°s.
We can express the given information at two ordered pairs as shown below:
![(n,l)=(11,34)\text{ and }(n,l)=(44,26)](https://tex.z-dn.net/?f=%28n%2Cl%29%3D%2811%2C34%29%5Ctext%7B%20and%20%7D%28n%2Cl%29%3D%2844%2C26%29)
Let us find slope of the line through these points:
![m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{26-34}{44-11}=\frac{-8}{33}=-0.2424](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%3D%5Cfrac%7B26-34%7D%7B44-11%7D%3D%5Cfrac%7B-8%7D%7B33%7D%3D-0.2424)
Therefore, we can write the equation of line in slope intercept form as:
![n=-0.2424l+b](https://tex.z-dn.net/?f=n%3D-0.2424l%2Bb)
Where b is the y intercept, and we can find its value using one of the two points.
![34=-0.2424(11)+b\\34=-2.67+b\\b=34+2.67=36.67](https://tex.z-dn.net/?f=34%3D-0.2424%2811%29%2Bb%5C%5C34%3D-2.67%2Bb%5C%5Cb%3D34%2B2.67%3D36.67)
Therefore, the required equation of the linear function is:
![n=-0.2424l+36.67](https://tex.z-dn.net/?f=n%3D-0.2424l%2B36.67)
Answer:
0.56
Step-by-step explanation:
There are 14 girls, and a total of 25 students. So the probability of selecting a girl is P = 14/25 = 0.56.
