If you have learned how to find the line of best fit manually, then you can do it that way. Perhaps you may want to just find a line that can connect at least two of the points and I believe that that line will be able to represent the other points because, in general, the points are pretty close to one another.
If you don't want to do it manually and have a graphing calculator (which I recommend) then you can use that to find the line of best fit (and if you want then you can see how precise your points are with your r^2 value). Or there is a website (http://illuminations.nctm.org/Activity.aspx?id=4186), which you can use to help you to find the equation of that particular line.
Once you have that done, then you can substitute 2009 for the x value in the equation and then see what y value the equation produces. That will then be your answer :)
This is easy angle (J,angle K,angle L)
You look a the line segment of the smallest one and what ever letter isn’t there is the smallest angle because there across from each other
We can write a proportion for this question
5 out of 32 students and we have to find how many (x) out of 800
5/32 = x /800
cross multiply
5*800 = 32x
4000 = 32x
divide both sides by 32
125 = x
About 125 students of the 800 ride their bikes to school.
Hope this helps :)
Answer:
Maria
Step-by-step explanation:
A typical snake bite delivers 0.0045 grams of venom.
Maria wrote it in scientific notation as ![4.5\times 10^{-3}](https://tex.z-dn.net/?f=4.5%5Ctimes%2010%5E%7B-3%7D)
Tammy wrote it in scientific notation as ![4.5\times 10^{3}](https://tex.z-dn.net/?f=4.5%5Ctimes%2010%5E%7B3%7D)
Any number can be written in the form of scientific notation as follows :
(a is real no and b is integer)
The given no is 0.0045.
There are 2 zeroes before 4. Also the decimal is there before 2 zeroes.
![0.0045=\dfrac{45}{10000}\\\\=\dfrac{45}{10}\times \dfrac{1}{1000}\\\\=4.5\times 10^{-3}](https://tex.z-dn.net/?f=0.0045%3D%5Cdfrac%7B45%7D%7B10000%7D%5C%5C%5C%5C%3D%5Cdfrac%7B45%7D%7B10%7D%5Ctimes%20%5Cdfrac%7B1%7D%7B1000%7D%5C%5C%5C%5C%3D4.5%5Ctimes%2010%5E%7B-3%7D)
Hence, Maria is correct.
