Select the correct answer. Participants in a survey were asked the number of hours of television they watch each week. The dot plot shows the distribution of their responses. After the data was recorded in the dot plot, another response was found for a participant who watches 30 hours of television each week. How will this additional data point affect the mean number of hours of television watched each week? A. The effect on the mean number of hours cannot be determined. B. The mean number of hours will decrease. C. The mean number of hours will increase. D. The mean number of hours will remain the same.

answer is more than one

step-by-step explanation:

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
