The residual plot for a data set is shown.

based on the residual plot, which statement best explains whether the regression line is a good model for the data set and why?

the regression line is a good model because some residuals are 0.

the regression line is not a good model because the points in the residual plot are far from the x-axis.

the regression line is a good model because the residuals approach 0 as x increases.

the regression line is not a good model because there is a pattern in the residual plot.

The regression line is not a good model because there is a pattern in the residual plot.

Step-by-step explanation:

Given is a  residual plot for a data set

The residual plot shows scatter plot of x and y

The plotting of points show that there is not likely to be a linear trend of relation between the two variables. It is more likely to be parabolic or exponential.

Hence the regression line cannot be a good model as they do not approach 0.

Also there is not a pattern of linear trend.

D) The regression line is not a good model because there is a pattern in the residual plot.

D.The regression line is not a good model because there is a pattern in the residual plot.

Step-by-step explanation:

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
