Answer: $16, 666.67
<u>Step-by-step explanation:</u>
Job 1: 0.06x
Job 2: 0.03x + 500
0.06x > 0.03x + 500
<u>-0.03x </u> <u>-0.03x </u>
0.03x > 500
<u>÷0.03</u> <u> ÷0.03 </u>

x > 16,666.67 <em>rounded to the nearest penny</em>
Percentage of people who buy Burgers = 35+45/2 = 80/2 = 40
Total Number of people = 900
So, 900 * 40%
= 900 * 0.40
= 360
In short, Your Answer would be: 360 burgers

The value of correlation coefficient (r) for the dataset is 0.981
<h3>What is correlation coefficient (r)?</h3>
The correlation coefficient (r) is used to determine the closeness and association of a scatter plot points.
The dataset is given as:
- x: 8 15 3 7 2 14
- y: 15 21 6 12 3 20
Using a graphing calculator, we have the following parameters:
<h3>X Values
</h3>
- ∑x = 49
- Mean = 8.167
- ∑(X - Mx)2 = SSx = 146.833
<h3>Y Values
</h3>
- ∑y = 77
- Mean = 12.833
- ∑(Y - My)2 = SSy = 266.833
<h3>X and Y Combined
</h3>
- N = 6
- ∑(X - Mx)(Y - My) = 194.167
The correlation coefficient (r) is then calculated as:
This gives


Approximate

Hence, the value of correlation coefficient (r) for the dataset is 0.981
