1 answer:

7 0

Answer:

47% is the statistic and 31% is the parameter.

Step-by-step explanation:

A parameter is a quantity of a variable representing certain characteristic of a population.

A statistic is a quantity of a variable representing certain characteristic of a sample.

The sample of parents of kindergartners selected is, <em>n</em> = 345.

The School records show that only 31% of parents of kindergartners sent their children to pre-kindergarten.

That is the population proportion is, <em>p</em> = 0.31.

This is the parameter value.

Of the 349 parents, 47% said they sent their children to pre-kindergarten.

That is the sample proportion is, $\hat p$ = 0.47.

This is the statistic value.

Thus, the correct option is:

47% is the statistic and 31% is the parameter.

Answer:

Step-by-step explanation:

Apply the distributed property:

See the other options:

Another option that looks like it could be the answer is 3(6x - 3) = 72
Apply the distributed property like we did above, so it now looks like this: 18x - 9 = 72
This is the same as what we got above, so it is also an answer.

Solve:

Add 9 to each side, so it now looks like this: 18x = 81
Divide each side by 18 to cancel out the 18 next to x. It should now look like this: x = 4.5
x = 45 is an option listed, so that's one of the answers.

I hope this helps!
