x^2 - 49 = 0
Add 49 to both sides:
x^2 = 49
Take the square root of both sides:
X = 7

It is NOT possible to determine the missing value from the given data.
<h3>Mean and Median</h3>
Mean is the average of a number of data while the median is the number at the middle of the given data.
- For a given data with a missing value, we can only find the missing value by calculating the mean of the data and equating the given mean.
Hence from the given data, it is NOT possible to determine the missing value from the given data.

We can model the equation:y = m x + b, where y is the total profit and x is the number of hotdogs sold.The system of equations is:
90 = 40 m + b210 = 80 m + b---------------------b = 90 - 40 m210 = 80 m + 90 - 40 m210 - 90 = 40 m120 = 40 mm = 120 : 40m = 3b = 90 - 40*3b = 90 - 120b = - 30Answer: The equation is y = 3 x - 30
