1. A flagpole casts a 42-foot shadow. If the angle of elevation of the sun is 57.4°, what is the height of the
flagpole?

25 ! the line of best fit is h = 5a + 86. predict the height at age 16. show your work.

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?

Aroulette wheel has 38 slots in which the ball can land. two of the slots are green, 18 are red, and 18 are black. the ball is equally likely to land in any slot. the roulette wheel is going to be spun twice, and the outcomes of the two spins are independent. the probability that it lands one time on red and another time on black in any order is(a) 0.5 (b) 0.25 (c) 0.4488 (d) 0.2244
