If there are 13 values in a data set in order from smallest to largest, what is the third quartile of the data set?
Vikki [24]
I am pretty sure the quartile is just the third number in a data set so it would 39? I do not recommend using this I am only 14 after all   <span />

The polynomial −2x2 + 700x represents the budget surplus of the town of Alphaville. Betaville's surplus is represented by x2 − 4
matrenka [14]

Answer:

- x²+ 300x + 50,000

Step-by-step explanation:

The polynomial −2x² + 700x represents the budget surplus of the town of Alphaville.

Again, Betaville's surplus is represented by x² − 400x + 50,000.

{where x is the tax revenue in thousands from both towns}

Now, the expression that represents the total surplus of both towns together will be

= (−2x² + 700x) + (x² − 400x + 50,000)

=  - x²+ 300x + 50,000

where x is the tax revenue in thousands from both towns. (Answer)

What is the area of the figure?
nirvana33 [79]

We can break it into two parts.

-> First, the rectangle on the bottom is made up of 2 feet x 16 feet. The formula for area of a rectangle is length times width, so in this case it is equal to 32 feet

-> Next, the triangle has sides of 10 feet, 10 feet, and 16 feet. We can calculate that the height is 6. The formula for area of a triangle is base times height divided by two, so, \frac{16*6}{2}= \frac{96}{2} = 48 feet

-> Last, we can add the two totals together. 32 feet + 48 feet = 80 feet giving us our final answer of 80 feet². As this answer is not pictured I am going to assume they are not including Heron's formula or other more complex formulas, leading us to the answer of "can't be determined"

Answer:

O can't be determined

Have a nice day! - <em>Note: It depends on the level of your math class for whether the answer "cannot be determined" is correct as it can be determined, just takes more effort than simple one - two-step formulas.</em>

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

     ★ Also please leave the rating you think I deserve (It helps other users as well as myself)

Here is what your frequency/cumulative frequency table would look like.  The cumulative frequency is where you add all the frequencies from before it to get a sum after each interval.

              <u> Frequency    </u>       <u>Cumulative Frequency</u>
0-25             8                              8
26-50           0                              8
51-75           4                             12
76-100         2                             14
