Marsha recorded the time it took six children of different ages to run one lap around the track using the line of best fit, which is the closest to the length of time it should take marsha’s 8 year old son to run one lap? A.168
B.176
C.182
D.190

D.190 i think sorry if  u get it wrong but that is what my "15" year old friend said hope he is correct.

Step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
