d. Predict the amount of new solar power that will be installed in 2013. Do you have much faith in your prediction? Explain, Round to the nearest tenth as needed.) O A. It is predicted that megawatts of new solar power will be installed in 2013. Since the model fits the data points, it is reasonable to assume that this value will be relatively accurate. OB. It is predicted that relatively accurate. megawatts of new solar power will be installed in 2018. Since 2013 is inside the domain of the given data, it is reasonable to assume that this value will be OC. It is predicted that megawatts of new solar power will be installed in 2013. Since the model does not fit the data points, there should be little or no faith placed in the accuracy of this value. OD It is predicted that megawatts of new solar power wvill be installed in 2013, Since 2013 is outside the doman of the given data, there should be ittle or no faith placed in the accuracy of this value.
