Answer:
The answer is 15%.
Step-by-step explanation:
The probability that:
- Both treatments are successful:
80% x 90% = 72%
- The first method is a success, but the second one is not:
80% x (1 - 90%) = 8%
- The first method is not successful, but the second one is:
(1 - 80%) x 25% = 5%
- Both treatments are unsuccessful:
1 - (72% + 8% + 5%) = 15%
Answer:
A) Proportion.
Step-by-step explanation:
The distribution of sample proportions leads or may tends to approximate a normal distribution and is an unbiased estimator that has a graph that is usually distributed and is not skewed. In other words, simply, we can also say that the population proportion is basically defined to be as the mean of the sample proportion. The population proportion is basically equaled the expected value of the sample proportion.

Answer: 2 markers.
Step-by-step explanation:
1. You know that she gives 12 markers to Mr. Cooke, then the rest among is:
29 markers-12 markers=17 markers
2. She divides the rest among 5 other teachers and each one of them get the same number of markers. So, you need to divide 17 markers by 5 teachers as following:
17 markers/5=3.4 markers
3. But the number of marker each one teacher has can't be a decimal number, so this number must be: 3 markers for each teacher.
3. The number of markers that will be left over is:
17 markers-(5*3 markers)=2 markers
