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.

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.

An estimate can only be made by surveying all 12,000 people in the town.

The larger the number of people Theo surveys, the better his estimation of the mean will be.

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.

wth is with the little mtn top and what are you talking about like fix your words and accually make sence with them and i like was in a completly different question like three times like it seems like your ilitteret

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
