Step-by-step explanation:
Use your fingers if necessary
11-5=6
18-11-7
26-18=8
........... so on and so forth.
I think you get the point.
The answer is c = .6x + 5
In order to find the equation, note that the price per pound is contingent upon the weight in x. Therefore, we can multiply the two together.
We also need to add the constant, which is 5.
These problems really aren't hard just set them equal to each other and see if what they are saying is true. Are they equal? Do they both equal 0?
We have the following data set:
2,7,15,3,12,9,15,8,3,10
The range is the difference between the highest and lowest values in the set, to find the range, order the data set from least to greatest.
2,3,3,7,8,9,10,12,15,15
Then,

Mean is represented by the following expression:


Population variance formula looks like this:

Then, substituting:

For the standard deviation:
