Which value best estimates the value for the correlation coefficient of the scatter plot: -1, -0.8, -0.2, 0.2, 0.8, or 1? Explain your reasoning.

step-by-step explanation:

graph using a few selected

x         y

-1       15

0         6

1         2.4

2       0.96

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
