A support vector machine has been built to predict whether a patient is at risk of cardiovascular disease. In the dataset used to train the model, there are two target levels$-$high risk $($the positive level, $+1)$ or low risk $($the negative level, $-1)-$and three descriptive features $-$ AGE, BMI, and BLOOD PRESSURE. The support vectors in the trained model are shown in the table below $($all descriptive feature values have been standardized$).$
