Step-by-step explanation:
not sure what class this is for but I\ll try. Each traveller has a 21 km drive so their fare should be equal.
method 1) each traveller can pay for 21 km worth when they get out
method 2) Curly can pay the full fare and Andy and Bob can pay him back later (they're brothers so this should be easy to manage)

Answer:
Unknown number, x=-4
Step-by-step explanation:
Forming the equation from the information provided above.
9=2x+17
If we solve for the unknown number, we first collect like terms together.
2x=9-17
2x=-8
Divide both sides of the equal sign by 2 the coefficient of x
x=-4
Answer:
99.9973 %
Step-by-step explanation:
This is a binomial probability distribution.
Since the probability of satisfactory welds = 97% = 0.97 and the probability of defective welds = 3% = 0.03.
Since there are 3 welds and we require at least one being defective, our binomial probability is
P(x ≥ 1) = 1 - P(x ≤ 0) = 1 - P(0) = 1 - ³C₀(0.03)³(0.97)⁰ = 1 - 1 × 0.000027 × 1 = 1 - 0.000027 = 0.999973 × 100% = 99.9973%
