Answer:
0.9964 is the probability that at least one of them meets specifications.
Step-by-step explanation:
We are given the following in the question:
B: Bolts meet the specification
N: Nails meet the specification
P(B) = 96% = 0.96
P(N) = 91% = 0.91
One bolt and one nail are chosen independently.
Thus, we can write
![P(B\cap N) = P(B) \times P(N) = 0.96\times 0.91 = 0.8736](https://tex.z-dn.net/?f=P%28B%5Ccap%20N%29%20%3D%20P%28B%29%20%5Ctimes%20P%28N%29%20%3D%200.96%5Ctimes%200.91%20%3D%200.8736)
We have to find the probability that at least one of them meets specifications.
![P(B\cup N) = P(B) + P(N) -P(B\cap N)\\P(B\cup N) =0.96 + 0.91-0.8736\\P(B\cup N) =0.9964](https://tex.z-dn.net/?f=P%28B%5Ccup%20N%29%20%3D%20P%28B%29%20%2B%20P%28N%29%20-P%28B%5Ccap%20N%29%5C%5CP%28B%5Ccup%20N%29%20%3D0.96%20%2B%200.91-0.8736%5C%5CP%28B%5Ccup%20N%29%20%3D0.9964)
0.9964 is the probability that at least one of them meets specifications.

a number increased by 14
Step-by-step explanation:
The phrases which can be represented by the algebraic expression x + 14 are
Let x = the unknown number
a number plus 14
= x + 14
fourteen more than a number
= x + 14
a number increased by 14
x + 14

Answer:
3 hours
Step-by-step explanation:
We know that $30 of the $105 bill was just to come to the house, leaving $75 of the bill due to the hours spent. Since the rate per hour is $25/hour, that means 75/25 = 3 hours were spent at the house
