If you are looking at the total of just people who have just bikes that's 40 and people who have just skateboards that's 10 so 30 but if its the total of bikes that's 72 and the total of skateboards that's 42 which is also 30. My best guess seeing as i don't know what math class you are in is 30.
Assuming the equation is 3x-2y+4=0 then the equation of the line, solving for y in terms of x, gives y=3/2x+2 the slope of this line is 3/2 then the slope of a line that is perpendicular is -2/3 .An easy way to see this is to draw the line. By definition the slope, m=tan(α) where α is the angle the line makes with the x axis. Let L=slope of the perpendicular line then L=tan(β) but the two lines with the x axis form a right triangle hence α+π-β=π/2 so β=π/2+α and L=tan(β)=tan(π/2+α)=-cot(α) = -1/tan(α)=-1/m.In our problem m=3/2 so L=-2/3.The geometry becomes clear if you make a sketch of the two lines. Hope this helps

Answer:
A. False
B. True
C. False
D. True
Step-by-step explanation:
The values range from 0 to 6 not 1 to 6.
There is a peak at 3 since it has 5 datas.
The mean is 3.471 not 3.
The median IS 3.
The question here asks for a number, such that if we multiply
by this number, the result will be bigger than
This means that this number, which we will call p, just needs to be bigger than 1.
So, it could be for example 1.5 that is
- this is the correct answer!
and let's check:
*1
