Answer:

a). (5,30) (0,20)

b). (40,130) (35,120)

Step-by-step explanation:

a). (5,30) (0,20)

solid red line's solutions are all going to be going down and dashed blue line's solutions will be going up all solutions in those regions are considered solutions

b). (40,130) (35,120)

points are non-solutions because they are not in the shaded region for either line's solution .

haven't done this in a hot minute so im not sure 100%

A football player completes a pass 69.4% of the time. Find the probability that (a) the first pass he completes is the second

wlad13 [49]

Step-by-step explanation:

(a) If his second pass is the first that he completes, that means he doesn't complete his first pass.

P = P(not first) × P(second)

P = (1 − 0.694) (0.694)

P ≈ 0.212

(b) This time we're looking for the probability that he doesn't complete the first but does complete the second, or completes the first and not the second.

P = P(not first) × P(second) + P(first) × P(not second)

P = (1 − 0.694) (0.694) + (0.694) (1 − 0.694)

P ≈ 0.425

P = P(not first) × P(not second)

P = (1 − 0.694) (1 − 0.694)

P ≈ 0.094
