This question relates to the survival function for a life s(x) = e-x/100 (a) Show that s(x) is a valid survival function. aged x:

Water temperature affects the growth rate of brook trout. The table shows the amount of weight gained by brook trout after 24 days in various water temperatures. Temperature (°C) 15.5 17.7 20.0 22.4 24.4 Weight gained (g) 37.9 31.4 19.0 9.0 -9.9 If W(x) be the weight gain at temperature x, construct a table of estimated values for W'. (Use a one-sided difference quotient with an adjacent point for the first and last values, and the average of two difference quotients with adjacent points for all other values. Round your answers to two decimal places.) w (x) 15.5 17.7 20.0 22.4 24.4

Can i have a worked example please. Thanks!

The Lorenz curve of income distribution in a small mountain nation is f(x)=0.5x¹ +0.3x³ +0.2x The Gini coefficient (index) of inequality for this nation is . . . O...y=0.562 O...y=0.513 O...y=0.37 O...y=0.45
