Well first we need to determine what each choices ( mean, median, mode, interquartile range) means.
Mean- average of a set of numbers
Median - middle number of a set of numbers
Mode- number that appears the most in a set of numbers
Interquartile range- find median of set of numbers and separate the set into 3 equal sections total. Subtract the 3rd section from the 1st section. So you can find the range or span of numbers.
If you want to build an elevator that can hold a maximum of 1,500 pounds, i think the most important fact you need to know about weight is the average weight that all the people weighs so you can know what to expect<span />

Hi there!
Let's solve this problem step by step!

To find f(3) we must substitute x = 3 into the formula.

Now we use PEMDAS (Parenthesis, exponents, multiply, divide, add, subtract) to find our answer.
Work out the exponents inside the parenthesis first.

And finally multiply.

Hence, the answer is D. 64.

Rachel sold more because 9/10 is equal to 0.90 and 5/8 is equal to 0.625.
This system can be a bit tricky unless you write it out:
(2n + 2)(2n - 2) ~ First you have to take one variable and multiply it to each of the other two variables, like:
2n * 2n ~ And:
2n * -2 ~ This gives you:
4n^2 - 4n
Now we do this with the other:
2 * 2n
2 * -2
4n - 4
Now we combine them both while adding like terms:
4n^2 - 4
Therefore your answer is: A. 4n^2 - 4
(This is due to how when having the positive 4n subtracted by the negative it cancels it out. Leaving us with the remaining two terms left.)
I hope this helps, have a great rest of your day! ^ ^
