The value of is 10 I think
Y = mx + c
m is the gradient of the graph, for each time you go across 1 x you go up y 'm' times, in your case you go up twice each time you go across once along x
c is the y intercept, the number where the y axis is cut and where you should start drawing your graph
I believe there would be 6 more girls than boys.
Answer:
22.67 containers.
Step-by-step explanation:
The number of cars washed is the average by the total hours worked:
![C_{total}=\bar xt,\bar x=8.5,t=8\\\\C_{total}=8.5\times 8=68](https://tex.z-dn.net/?f=C_%7Btotal%7D%3D%5Cbar%20xt%2C%5Cbar%20x%3D8.5%2Ct%3D8%5C%5C%5C%5CC_%7Btotal%7D%3D8.5%5Ctimes%208%3D68)
Given that each car uses 1/3 tin of wax, the total containers is calculated as:
![Containers=\bar x_c n,n=68,\bar x_c=\frac{1}{3}\\\\=\frac{1}{3}\times 68\\\\=22.67](https://tex.z-dn.net/?f=Containers%3D%5Cbar%20x_c%20n%2Cn%3D68%2C%5Cbar%20x_c%3D%5Cfrac%7B1%7D%7B3%7D%5C%5C%5C%5C%3D%5Cfrac%7B1%7D%7B3%7D%5Ctimes%2068%5C%5C%5C%5C%3D22.67)
Hence, the car wash uses 22.67 containers of wax per day.
5/2 = 2.5
you can check by multiplying 2.5 and 2.
