amountOfRain would be the most appropriate identifier for a memory location that will store the amount of rainfall for a given period of time.
<u>Explanation:</u>
A set of characters in a sequence that helps in the identification any value or a set of set is known as identifiers. Identifiers are unique in nature. A character sequence that is given for storing a set of data should not be given to store another set of data.
They are useful in referencing a variable from which the data or values that are contained in that particular variable can be easily retrieved. For example a variable can be indicated by an identifier totalAmount in which the value stored is 56000. The starting name of the variable should be given in smaller case letter and second name should be in capital letter. For instance if you are going to store the value 45 in the variable amountoftime then the variable name should be given as amountOfTime.
Answer: Pure play
Explanation:
A pure play method in finance is an approach that is used to estimate and determine the cost of equity capital of a private company which involves looking at the beta coefficient of other single focused and public companies.
Pure-play companies are the companies that are involved in a single line of business.

Answer:
![\bar X = \frac{17+12+9+16+14}{5}= 13.6min](https://tex.z-dn.net/?f=%20%5Cbar%20X%20%3D%20%5Cfrac%7B17%2B12%2B9%2B16%2B14%7D%7B5%7D%3D%2013.6min)
So then the best answer for this case would be:
a. 13.6 minutes
Explanation:
For this case we have the following data for the response rates:
17,12,9,16,14
And we want to calculate the mean response time for 911 calls in this village.
And for this case we use we can use the definition of sample mean given by:
![\bar X = \frac{\sum_{i=1}^n X_i}{n}](https://tex.z-dn.net/?f=%20%5Cbar%20X%20%3D%20%5Cfrac%7B%5Csum_%7Bi%3D1%7D%5En%20X_i%7D%7Bn%7D)
Where n = 5 represent the sample size for this case. If we replace we got:
![\bar X = \frac{17+12+9+16+14}{5}= 13.6min](https://tex.z-dn.net/?f=%20%5Cbar%20X%20%3D%20%5Cfrac%7B17%2B12%2B9%2B16%2B14%7D%7B5%7D%3D%2013.6min)
So then the best answer for this case would be:
a. 13.6 minutes
The sample mean is an estimator unbiased of the population mean because:
![E(\bar X) = E(\frac{\sum_{i=1}^n X_i}{n}) = \frac{1}{n} \sum_{i=1}^n E(X_i) = \frac{n\mu}{n}= \mu](https://tex.z-dn.net/?f=%20E%28%5Cbar%20X%29%20%3D%20E%28%5Cfrac%7B%5Csum_%7Bi%3D1%7D%5En%20X_i%7D%7Bn%7D%29%20%3D%20%5Cfrac%7B1%7D%7Bn%7D%20%5Csum_%7Bi%3D1%7D%5En%20E%28X_i%29%20%3D%20%5Cfrac%7Bn%5Cmu%7D%7Bn%7D%3D%20%5Cmu)
For this reason is a good statistic if we want to see central tendency in a group of values.
