In an effort to check the quality of their cell phones, a manufacturing manager decides to take a random sample of 10 cell phones from yesterday's production run, which produced cell phones with serial numbers ranging (according to when they were produced) from 83009000 to 8300. assume that each of the 1000 phones is equally likely to be selected.
a) what distribution would they use to model the selection?
b) what is the probability that a randomly selected cell phone will be one of the last 125 to be produced.
c) what is the probability that the first cell phone selected is either from the last 231 to be produced or from the first 73 to be produced.

40 points plato monica built a remote-controlled, toy airplane for a science project. to test the plane, she launched it from the top of a building the plane traveled a horizontal distance of 50 feet before landing on the ground. a quadratic function which models the height of the plane, in feel, relative to the grouna, at a horizontal distance of x feet from the butiding is shown. since the domain the airplane while it was in the air, the value of the domain should be restricted to the space 1 a.the maximum height of b.the horizontal distance covered by c.all the heights in the trajectory of space 2 a.-10 b.125 c.negative infinity d.0 space 3 a.infinity b.50 c.125 d.225
