Answer:

If samples of size 50 are taken, the distribution of the sample arithmetic mean must be approximately normal. The arithmetic mean is an unbiased, efficient, sufficient and consistent estimator of the population mean. Therefore, the best punctual estimator of the population mean is the sample arithmetic mean (the sum of the 50 values of the housing prices divided by 50).

Which expression shows the correct way to expand (6x-6)^2?
jeka94

Answer:

(6x -6)^{2} = (6x +6)(6x +6) = 36x^{2} -72x + 36

Step-by-step explanation:

Even if I don't know the options I can give all the option that will be right for expending this. Just look at each step and see which one is one of the options.

(6x -6)^{2} = (6x +6)(6x +6) = 36x^{2} -72x + 36

Louise, Tammy, Delores, and Sheryl score 78 points total in the tennis matches they play. They score a consecutive number of poi
irga5000 [103]

\huge\boxed{18\ \text{points}}

We'll represent Louise's, Tammy's, Delores's, and Sheryl's point values with x, x+1, x+2, and x+3 respectively since each one is 1 point more than the last.

Add all of these values up and set it all equal to 78.

x+x+1+x+2+x+3=78

Now, simplify.

4x+6=78

Subtract 6 on both sides.

\begin{aligned}4x+6-6&=78-6\\4x&=72\end{aligned}

Divide both sides by 4.

\begin{aligned}\frac{4x}{4}&=\frac{72}{4}\\x&=\boxed{18}\end{aligned}

Since Louise's score is x, the answer is 18.

<h3>Double-checking</h3>

To verify our answer, add the point totals 18, 19, 20, and 21.

This equals 78, so we can be sure the answer is correct.
