Answer:
21.16
Step-by-step explanation:
Starting from the theory we have the following equation:
Using the data supplied in the exercise, we have subtracting the mean and dividing by the standard deviation:
solving for "c", knowing that fi is a tabulating value:
therefore the value of c is equal to 21.16
1. The question about the weight of the football team players is statistical because it requires data collection to answer it and the data is variable.
2. The question about the height of Ben's mother is <u>non-statistical</u> because it does not require data collection to answer and the data is not variable, since it is one data point.
<h3>What is a statistical question?</h3>
A statistical question can be answered by collecting data and for which data will vary.
Questions answered with a single data point are <u>not statistical</u> because there is no data variability to answer them.
A statistical question can be determined by the following criteria:
- Provides useful data about a group of people.
- Many people can answer it.
- There will be many different answers.
- The data collected explains a situation or reality.
Thus, the question about the weight of the players asks a statistical question, unlike the height of Ben's mother.

A, c, and d
plug in each x in the equation and it should equal the y value
First off we want to combine "like-terms"
1. Subtract 6x , so it will look like this: 2x-6x+12=-12
2. Subtract the -12 from the first side so it looks like 2x-6x=-12-12
3. Combine like terms. So: -3x=-24 . The negatives will cancel out when dividing 24/3.
The final answer is 8 after dividing. Hope this helped!
