Answer:
-147
If your question is 3(5x -9) then you answer is 15x-27
Step-by-step explanation:
The modified r squared tells us more about the relationship among sales, price, as well as advertising by explaining approximately 60% of a variance in sales.
<h3>Define the term adjusted r squared?</h3>
R-squared (R2) would be a statistical measure that quantifies the proportion of the variation explained from an independent variable other variables within a regression model for a dependent variable.
- R-squared describes how much the variance with one variable describes the variance of the other.
- So, if a model's R2 is 0.50, the model's inputs can explain roughly half of a observed variation.
- A score of 70 to 100 shows that a specific portfolio closely reflects the underlying stock index, whereas a score of 0 to 40 indicates a relatively poor correlation the with index.
- Higher R-squared scores also suggest that beta measurements are more reliable. The volatility of either a security or portfolio is measured by beta.
Thus, the modified r squared tells us more about the relationship among sales, price, as well as advertising by explaining approximately 60% of a variance in sales.

2/3x=(-20)
X=(-20)x 3/2 ( 2/3 actually changes into 3/2(it's reciprocative form)when the number crosses the equal sign)
X=(-10) x 3
X= (-30)
Hope it helps....
Answer:
-1\4
Step-by-step explanation:
take change in y\change in x
hence:
10-9\6-10
