What’s the probability of the coin landing on Heads? We can find out using the equation P ( H) =? . You might intuitively know that the likelihood is half/half, or 50%. But how do we work that out? Probability = In this case:Using “ages” as the independent variable and “Number of driver deaths per 100,000” as the dependent variable, make a scatter plot of the data. Calculate the least squares (best–fit) line. Put the equation in the form of: ŷ = a + bx. Find the correlation coefficient.

An extremely large meteor crashed into the earth at the time of the disappearance of the dinosaurs. russian celebrationkansas jayhawks vs arkansas Sum of original 6 numbers = 20 × 6 = 120. Sum of remaining 5 numbers = 15 × 5 = 75. Number removed = sum of original 6 numbers – sum of remaining 5 numbers. Number removed = 120 – 75 = 45. Alternative Method: Let x be the removed number. The removed number is 45. Example: 10 students of a class had a mean score of 70.Solutions to the Above Problems. a) Let us organize the data in a table. b) We now graph the regression line given by y = a x + b and the given points.
