123/0.75 =164
the answer is 164
This system will have 1 solution, or C. That's because since the equations are different, meaning that there is 1 solution.
Answer:a
Step-by-step explanation:
Answer: 1/20
To find P(Q and R), you have to multiply P(Q) by P(R) to get the probability that both events will occur. P(Q) = 1/8, and P(R) = 2/5, so when multiplied together, you get 2/40. This simplifies to 1/20, meaning P(Q and R) = 1/20.
