Hannah surveyed 1/9th of the population.
The sample wouldn't really be representative of the population, because of the
small sample size. 
Based on the table, you could expect around 60% of the students to own a cat or a dog. This is because there are 30 students with a pet, and 20 without, which makes a percentage of 60% students that own a pet.

Which is a zero of the quadratic function f(x) = 16x?? + 32x - 9?
STALIN [3.7K]

Answer:

f(x) = 16x2 + 32x - 9

 

To find the "zeros", set f(x) = 0:

 

    0 = 16x2 + 32x - 9

 

The equation is solvable by factoring or by using the quadratic formula.  The factors (use the "ac" method) are:

 

    0 = (4x-1)(4x+9)

 

    x = 1/4 = 0.25 and x = -9/4 = -2.25

To find the average you would add the three numbers together 169.74+235.95+219.21
to get a total of $624.90 divide that number by 3 to get the average which is $208.30 as the average sale per day

Brut [27]

Answer:

  (d)  f(x) = (x − 3)^2(x − 2)(x − 1)

Step-by-step explanation:

In this context, a crossing of the axis at x=p means there is a factor of (x-p). A "touch" of the axis at x=q means there is a factor of (x -q)^2.

A crossing at x=1 and x=2, and a touch at x=3 means the factors are ...

  f(x) = (x -1)(x -2)(x -3)^2 . . . . . matches the last choice
