Answer:
A, or 8
Step-by-step explanation:
the total angle is 102, so we can subtract 54 from 102 to get 6x, then divide by 6.
102 -54 = 48/6 =8

10×2 = 20
20-16=4
Answer:
The quadratic equation is x^2 + 4x - 32 = 0
Step-by-step explanation:
(x - 4)(x+8) = 0
x^2 + 4x - 32= 0
Answer:
a) 23.76%
b) 7.8%
Step-by-step explanation:
a) probability that a failure is due to loose keys.
loose key failure (27%) comes under mechanical failure(88%)
hence, probability that a failure is due to loose keys= 0.27×0.88= 0.2376= 23.76%
b) probability that a failure is due to improperly connected wire which comes under electrical failure = 0.12×0.13
probability that a failure is due to poorly welded wires which comes under electrical failure= 0.52×0.12
now, the probability that a failure is due to improperly connected or poorly welded wires. = 0.12(0.52+0.13)= 0.078= 7.8%
