A frequency polygon for the times taken by 18 people to complete a puzzle is shown in the image attached below.
<h3>How to draw a frequency polygon?</h3>
In order to draw a frequency polygon for the given data, we would construct a frequency table as follows:
<u>Time, t minutes Frequency</u>
0 < t ≤ 10 5
10 < t ≤ 20 5
20 < t ≤ 30 7
30 < t ≤ 40 1
Next, we would determine the midpoint of the data set:
- 10 < t < 20 = (10 + 20)/2 = 15.
- 20 < t < 30 = (20 + 30)/2 = 25.
- 30 < t < 40 = (30 + 40)/2 = 35.

If we assume that ST = 2x + 2, and that TW = 4x - 4, then we can just add the two segments together, as shown below (IF you're asking for the length, that is).
(2x + 2) + (4x - 4)
2x + 2 + 4x - 4
Group together like terms.
(2x + 4x) and (2 - 4)
6x (+) - 2
Answer: 6x - 2
Answer:
a + b ≥ 40
a + 5 ≤ b
2.50a + 1.50b ≤ 105
Step-by-step explanation:
We are told she would like to have at least 40 cupcakes and cookies combined.
If a is number of cupcakes and b is number of cookies, then this inequality is;
a + b ≥ 40
Secondly, we are told she would like to have at most 5 more cupcakes than cookies.
Thus, the inequality is;
a + 5 ≤ b
Lastly, we are told that cupcakes sell for $2.50 and cookies for $1.50
Thus, the inequality is;
2.50a + 1.50b ≤ 105
Finally, the 3 inequalities are;
a + b ≥ 40
a + 5 ≤ b
2.50a + 1.50b ≤ 105
1/12th of 60 is 5 (5 x 12 = 60)
