WebThe daily mean wind speed, w knots, and the daily maximum gust, g knots, were recorded for the first 15 days in May in Camborne. The data was plotted on a scatter diagram. The equation of the regression line of g on w for these 15 days is g =7.23+1.82w. Predict the daily maximum gust when the daily mean speed is 16 knots. WebLogarithms and Significant Figures The common logarithm of a number is the power or exponent to which the base number 10 must be raised to give the number. For example, if the number is N and N = 10 x, then the logarithm of N is x, or log N = x. Logarithms of integral powers of ten are easy to find.
