Answer: $12000 was invested at 7% while $8000 was invested at 9%.
Step-by-step explanation:
Based on the information given in the question, let the amount that was invested at 7% be n.
Therefore,
0.07n + 0.09(20000 - n) = 1560
0.07n + 1800 - 0.09n = 1560
-0.02n = 1560 - 1800
-0.02n = -240
n = 240/0.02
n = 120
Therefore, $12000 was invested at 7% while $8000 was invested at 9%.

Answer:
Binomial Distribution
Step-by-step explanation:
In this case there are only two possible outcomes that is either the processor requires repair or does not require.
In such cases binomial distribution is beneficial to use.
Binomial Distribution is simply the probability of failure or success in an experiment that is repeated multiple times.
for binomial to be used following three conditions are to be used:
1. Fixed number of trails
2. Each trial or observation is independent
3. probability of success is exactly same
