<h3>How to Construct a Dot Plot?</h3>To construct a dot plot, each data point is represented as a dot. The number of dots one data point has represents the frequency at which that data point occurs in the data set.
The data set given in the table will have the following data points and frequencies:
1: 1
2: 3
3: 4
4: 4
5: 4
6: 0
7: 2
8: 2
The dot plot for the data is shown in the image below.

Step-by-step explanation:
<u>Use identities to set the equation up as a quadratic</u>
<u>Make the substitution u=cos(x) and solve the quadratic</u>
<u />
Hence,
For 5 games, the cost will be equal for each option.
Step-by-step explanation:
Given,
Lane rental of offer A = $20
Per game charges = $3
Let,
x be the number of games.
A(x) = 3x + 20
Lane rental is $35 for maximum 10 games.
B(x) = 35
For the cost to be same;
A(x) = B(x)
Dividing both sides by 3
For 5 games, the cost will be equal for each option.
