The data below are the ages and systolic blood pressures (measured in millimeters of mercury) of 9 randomly selected adults. The equation of the least squares regression line is found to be y with hat on top equals 60.46 plus 1.488 x space . Use the regression line to predict the systolic blood pressure of a person who is 43 years old. Round to the nearest millimeter.

Someone answer asap for ! the boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a. e = 2b - 212 b. b = 2e - 212 c. e = -2b + 212 d. b = -2e + 212

Determine if the equation defines y as a function of x: 2xy = 1. yes o no
