1260
- 210
50
The ratio of voters to nonvoters is 210 to 50.
Answer:
Part A: yes
Part B: 50%
Step-by-step explanation:
There are two ways we can use a normal approximation for a sample: if the population it is from is normally distributed, or if the sample is sufficiently large (n > 30). In this case, we don't know if the population is normally distributed, but we do know the sample size is larger than 30, so we can use normal approximation.
The sample proportion is normally distributed, with a mean equal to the mean of the population. So there is a 50% chance that sample proportion is less than the population proportion.
To find the average number of enrollments per day, what you would want to do is add all of the numbers and then divide it by how many numbers there are.
Your Equation would look like this:
17+19+23+14+25+28 = ?
When you solve it. you would get:
126
126 would be the total amount of enrollments, but the question is asking you to find the average enrollments PER day. In this case, you would divide your total enrollments by how many numbers there are in the question. There are 6 numbers in the question, or six days, that being 17, 19, 23, 14, 25, and 28. So you would get your total amount of enrollments and divide it by 6
Your equation would look like this now:
126÷6=21
The average number of enrollments per day is 21.
Answer:
1) x and y --> Variable(s)
2) 1/6 --> Constant(s)
3) 12.1, 4.7, and 6 --> Coefficient(s)
4) 12.1x and 6x --> Like Terms
5) 12.1x, 4.7y, and 1/6 --> Terms
