Answer:

m∠C = 43.6°, m∠B = 107.4°, b = 51.2

Step-by-step explanation:

Use the law of sines:

a / sin ∠A = c / sin ∠C
26 / sin 29° = 37 / sin ∠C
sin ∠C = 37 sin 29° / 26
sin ∠C = 0.6899
m∠C = arcsin 0.6899
m∠C = 43.6°

Find the missing angle:

m∠B = 180° - 29° - 43.6° = 107.4° (rounded)

Use the law of sines to find the length of b:

a / sin ∠A = b / sin ∠B
26 / sin 29° = b / sin 107.4°
b = 26 sin 107.4° / sin 29°
b = 51.2 units (rounded)

Among 9 electrical components exactly one is known not to function properly. If 3 components are randomly selected, find the pro

kozerog [31]

Answer:

P=0.66

Step-by-step explanation:

We know that Among 9 electrical components, exactly one is known not to function properly. If 3 components are randomly selected.

We calculate the probability that all selected components function properly.

We calculate the number of possible combinations:

$C_3^9=\frac{9!}{3!(9-3)!}=84$

We calculate the number of favorable combinations:

$C_3^8=\frac{8!}{3!(8-3)!}=56$

Therefore the probability is:

$P=\frac{56}{84}\\\\P=0.66$
