Solution :
Faulty electrical connects = P(A) = 0.80
Mechanical defects = P(B) = 0.92
Mechanical defects are related to loose keys = P(C/B) = 0.27
Improper assembly = P(D/B) = 0.73
Defective wires = P(E/A) = 0.35
Improper connections = P(F/A) = 0.13
Poorly welded wires = P(G/A) = 0.52
Now, the probability due to loose keys = 0.27 x 0.92 = 0.2484
Improperly connected = 0.13 x 0.80 = 0.1040
Poorly welded wires = 0.52 x 0.80 = 0.4160
So, the probability that a failure is due to improperly connected or poorly welded wires = 0.1040 + 0.4160
= 0.5200
Answer:
24° and 66°
Step-by-step explanation:
Angle 1 = x
Angle 2 = x + 42°
x + x + 42° = 90°
Subtract 42° from both sides and add
2x = 48°
Divide by 2
x = 24°
24° and 66°

Answer:
∠ECF = 37°
Step-by-step explanation:
∠ACG = 37° because it is a complementary angle to 53° (37° + 53° = 90°)
∠ECF = 37° because it is a vertical angle to 37°
