1st Step - Find the mean (average):
245 + 300 + 325 + 465 + 100 = 1435
1435/5 = 287 ( mean)

2nd step find the sun of the sqaure the difference between the gievn data and the mean

287 - 245 = 42^2 = 1,764
300 - 387 = 13^2 = 169
325-287 = 38^2 = 1,444
465 - 287 = 178^2 = 31,684
287 - 100 = 187^2 = 34,969

1,764 +169 + 1,444 + 31,684 + 34,969 = 70,030

Now divide that by the number of samples minus 1 ( 5-1=4)

70,030 / 4 = 17,507.5

 The variance = 17, 507.5

Write a function numberofpennies() that returns the total number of pennies given a number of dollars and (optionally) a number
ElenaW [278]
What language are you writing this in? C? Javascript? Java? Are you allow to have parameters? 
The general idea should be the same. Since 1 dollar  = 100 pennies, we should write something like...

Java:
public static double numberofpennies(double dollars, double penny) {         
           double sum = 0;                  

           // The amount of pennies that dollar represents       
           double converted = dollars * 100.0;                  

           sum = converted + penny;
         
           return sum;   
}
Note: You should probably place this question under the category computer and technology instead of math. Also, this is just an example of what you could possibly write. What parameters you are allowed to use, what type (double? int? etc?) of pennies are you allowed to return, etc. depends on how you write it.
