The table shows the approximate number of minutes of physical exercise each student in Noah’s class gets per day. Use the data to answer questions 1, 2, and 3. AMOUNT OF PHYSICAL EDUCATION TIME PER DAY (min) # OF STUDENTS 0 XX 15 XX 20 30 X 45 XX 60 XXX 120 X 180 X 1. Calculate the median of the data set and interpret its meaning in the context of the data. 2. Calculate the interquartile range of the data set and interpret its meaning in the context of the data. 3. Identify and interpret the meaning of any extreme values in the data set.

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

answer: i believe its b. if you sound out the sentences that sounds wrong.
