Grogain and follicleplus are hair regrowth systems. each company claims that the application of their product will cause hair regrowth for balding men. a barber decided to test each company's claim. he randomly selected 30 of his customers who had similar balding issues and asked 15 of them to use grogain and 15 of them to use follicleplus. after observing the men for six months, the barber reported that, on average, those who used grogain had a 20% increase in hair regrowth and those who used follicleplus had a 10% increase in hair regrowth. what conclusion can be made form this observation?

step-by-step explanation:

one set of data has more variation than the other. hope this !

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
