Hi I need help with these maths questions and over what is the power model compared to exponential and linear model

away from the road. This graph is the residual plot associated with a scatterplot of concentration against distance from a roadway (in km) for the change in the level of a pollutant from car exhausts as you go D.8 Which of the following statements is consistent with this evidence? Residual O 0.8 0.2 0.4 0.8 Explanatory Select one: O a. An exponential relationship, either positive or negative, is indicated between the pollutant concentration and the distance. X b. A power law model is indicated with a negative association. O c. There is insufficient evidence to decide on any specific type of relationship between the variables, except that the linear relationship is NOT appropriate. O d. A linear plot is indicated so the relationship between pollutant concentration and distance is linear. O e. An exponential model is clearly indicated with a negative association.tion 9 Given below are three(3) different plots of the same data showing how the amount of heat radiation transferred from an object changes with the temperature of the object. Note rect that the scales used for the x and y axes are different. 0.0 out of Which of the following statements is the most correct about the relationship between heat radiation and the temperature of this body. Base this on just the observation of the g question following plots ("imagine" the corresponding residual plots). B lack -body rad latb . us . Tem pe rate re Log-bg pbtor Radiatbi us . Temperature 200 1500 Log( Rad) Log DO 300 600 55 6.5 DO 300 500 Degrees K Degrees K Log(Temp) Select one: O a. The markedly increasing slope indicates that this may be an exponential growth pattern. O b. A power law model is indicated with a positive association. O c. There is insufficient evidence to decide on any specific type of relationship between the variables. X d. A linear plot is indicated, so the relationship between heat radiation and temperature is linear. O e. A power law model is indicated with a negative association
