Mean :207/13 so about 15.9
Median: 16
Interquartile
Q1:8
Q2: 25
I think I didn’t write it out
Answer:
x = all real values
Step-by-step explanation:
3(2x -5) = 6x -15
Distribute
3*2x - 3*5 = 6x-15
6x -15 = 6x -15
Subtract 6x from each side
6x-15-6x = 6x-15-6x
-15 = -15
This is always true so there are infinite solutions
x = all real values
Answer:
The constant of proportionality is 5.
Step-by-step explanation:
If the quantity q varies inversely with the square of m and directly with the product of r and x, then the variation equation is
![q=k\frac{rx}{m^2}](https://tex.z-dn.net/?f=q%3Dk%5Cfrac%7Brx%7D%7Bm%5E2%7D)
When q=2.5, m= 4 and the
product of rx = 8.
We plug in this values to get;
![2.5=k(\frac{8}{4^2})](https://tex.z-dn.net/?f=2.5%3Dk%28%5Cfrac%7B8%7D%7B4%5E2%7D%29)
![2.5=k(\frac{8}{16})](https://tex.z-dn.net/?f=2.5%3Dk%28%5Cfrac%7B8%7D%7B16%7D%29)
![2.5=\frac{1}{2}k](https://tex.z-dn.net/?f=2.5%3D%5Cfrac%7B1%7D%7B2%7Dk)
Multiply both sides by 2
![k=2.5\times 2=5](https://tex.z-dn.net/?f=k%3D2.5%5Ctimes%202%3D5)
The constant of proportionality is 5.
False. To find the decimal point while multiplying, count the number of decimal places (to the right of the decimal) in the factors. Then use the total of decimal places and move to the product. Start on the left side, and move the decimal over one number place for each decimal place.
Example: 3.77*2.8=?
3.77
* 2.8
----------
10556
But this is without the decimal point.
3.77 has two decimal places, and 2.8 has one. Put them together and you get a total of three decimal places.
10556, then, should have three decimal places.
Your answer would be 10.556
I hope this wasn't too confusing.
