Iseriously need this and have literally asked

assume that you pick real numbers a and b at random between 0 and 10. find the probability of each of the following.

the point (a, b) is in the upper triangle formed by the diagonals of a square whose sides lie on the axes and the lines x =10 and y=10

the function y=(1/x-a ) +b has a horizontal asymptote

An automated water dispenser fills packets with one liter of water on average, with a standard deviation of 5 milliliter. the manual says that after a year of operation the dispenser should be tested to see if it needs recalibration. a year later a number of filled packets are set aside and measured separately. it is found that the average packet now contains about 0.995 liters. does the dispenser need calibration? explain your answer.

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
