Given:
The ratio and rates:
1. 30 ft. To 60.Ft
2. 51 males to 21 females
3. 1,500 meters in 6 seconds
4. $36 for 4 rounds of shrimp
To find:
The fraction in simple terms for the given ratio and rates.
Solution:
1. 30 ft. To 60.Ft
2. 51 males to 21 females
3. 1,500 meters in 6 seconds
4. $36 for 4 rounds of shrimp
Answer: The answer is B or 2.
Step-by-step explanation:
A mapping system is a way of describing
a C. Preimage of a figure. Mapping statements are known to define the range of
data sources thus showing all the data. While on the other hand, preimage (in
Mathematics) meaning is that set of all the elements of the domain that maps to
the members of S.

Using confidence interval concepts, it is found that:
a) The point estimate is the sample mean.
b) The confidence interval is: 
c) If $1411 is between the bounds of the interval yes, otherwise no.
--------------
- At item a, it asks to provide a point estimate for the population mean, which is the sample mean
--------------
Item b:
- In the spreadsheet, it is possible to find the <em>standard deviation for the sample</em>, thus, the t-distribution is used.
- The confidence interval will be given by:
In which:
- is the sample mean.
- T is the critical value, from the t-distribution, with a two-tailed area of
and n-1 degrees of freedom. - s is the standard deviation for the sample.
- n is the sample size.
--------------
Item c:
We have to check if 1411 is between 
and 
.
- If it is, the interval includes the National Average, otherwise, it does not.
