Theo would like to estimate the mean number of vehicles each person owns in his town. The town has a population of 12,000 people. Which statements are true?
Select each correct answer
An estimate can only be made by surveying all 12,000 people in the town
To estimate the mean number of vehicles owned using a sample, Theo needs to randomly select the people he will survey
so that his sample represents the population well.
If Theo collects a sample of people at the car dealership and surveys them, he can use that data to estimate the mean
number of vehicles each person owns in his town.
The larger the number of people Theo surveys, the better his estimation of the mean will be.

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a

step-by-step explanation:

mark brainliest!

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
