4. Which correlation coefficient is stronger 0.52 or -0.52?

What is 32+4 x (16 x 1/2) -2 show your work}

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.

My hour hand points between the 8 and the 9 in 35 minutes it will be the next hour. what time is it ?
