See below for answers (in bold) and explanations
Step-by-step explanation:
8) There is a strong negative correlation between variables x and y, making option B, 0.8, the correct answer. If it were 1.0, we would have no residuals.
7) y=x+2 is the best equation that represents the line of best fit because the residuals are very small.
5) Notice how in option B the line does not overlap any of the points in the scatterplot. This is not the correct line of best fit while the other options are.
4) A and C both show a positive correlation while D is negative and B has no correlation between variables x and y.
2) If x represents how much fertilizer in ounces she adds to the soil and y represents the predicted value of the number of blooms each rose bush has, then Olivia will only have 4 blooms when she adds no fertilizer because:
4=1.345x+4
0=1.345x
0=x
