The speed of 10 ferris wheels is sampled. the speed, measured in miles per hour, are 10, 10, 12, 14, 10, 9, 8, 14, 12, 15 what is the best estimate of the population mean for the speed of a ferris wheel?

What is the correlation coefficient for the data? don't forget to turn the diagnoisticon (in the catalog menu of the calculator). r = answer (round to the nearest thousandth)

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.
