Rohit wants to find the best model for a bivariate data set. he used a calculator to create a linear model, a quadratic model, and an exponential model. the coefficient of determination for the linear model was 0.85. the coefficient of determination for the quadratic model was 0.90. the coefficient of determination for the exponential model was 0.81. which model should he use to represent the data set?

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

Someone answer asap for ! max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a. the median of max’s data is 250 b. more than half of the data points max recorded were 177 centimeters. c. a data point chosen at random is as likely to be above the mean as it is to be below the mean. d. every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
