Shantel and Syrus are researching what types of novels people prefer. They decide to survey people at the mall. Shantel uses systematic sampling and asks every seventh person at the entrance. She finds that 22% prefer fantasy novels. Syrus uses convenience sampling and asks every person in only one store. He finds that 45% prefer fantasy novels. Whose inference do you agree with? Explain. What mistake might the incorrect friend have made?

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

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)
