Answer:
Factorization
Step-by-step explanation:
This can be easily factorized into (x+7)(x+9)=0 which can be solved for the two roots x = -7 and x = -9
21000 people paid for general admission and 6000 paid for reserved seats. This is solved by making 2 equations. Out of 27000 people who were at game, x of them paid for general admission and y for reserved seats, thus
x + y = 27000
As said, daily receipts were 204000$. As reserved seat is 13$, y of them gave 13$ each (y*13$) and x of them gave 6 for general admission(x*6) and those two add up and we get second equation
13y + 6x = 204000.
This can be solved by transforming first equation into x = 27000 - y and then replacing the x in second.
13y + 6*(27000 - y) = 204000
13y + 162000 - 6y = 204000
7y = 42000
y = 6000
x + 6000 = 27000
x = 27000 - 6000 = 21000
The statements are true about the residual plot and the equation for the line of best fit include:
- The equation for the line of best fit is not a good approximation for the data because the points have a curved pattern.
- The residual plot has the pattern of a curve.
<h3>
What is Residual plot?</h3>
This shows the residuals on the vertical axis and the independent variable on the horizontal axis.
Since the plot has a curved pattern, the equation for the line of best fit is not a good approximation for the data as the result will be inaccurate.
