Answer:
PQ = 16
Step-by-step explanation:
PQ + QR = PR
(x + 6) + (3x) = 5x -4
4x + 6 = 5x -4
x = 10
10 + 6 = 16
Answer:
Expected value E = $0.45
Step-by-step explanation:
Expected value E = P×w - P'×l
Where;
P = probability of making the next 2 throw.
P = 223/406 × 223/406 = 0.3017
P' = probability of not making a throw.
P' = 1 - P = 1 - 0.3017
P' = 0.6983
w = expected win = $20
l = Expected loss = $8
Substituting the values;
E = 0.3017 × $20 - 0.6983 × $8
E = $0.4476
Expected value E = $0.45
Mx - y
5x-y
5(3)-y
15-y
15-8 = 7
7 is your answer.
