Mathematics
1 answer:
Degger [83]3 years ago
8 0

Answer:

Option (D)

Step-by-step explanation:

Kevin delivers newspaper in his town and earns an amount represented by a linear equation,

y = 30x + 18

Here, y = total earnings

x = number of houses he delivers the newspaper

If he doesn't deliver any newspaper on a certain day, (x = 0)

Then total earnings, y = 30(0) + 18

y = 18 cents

Therefore, a certain amount of 18 cents will be paid even if he doesn't deliver any newspaper on a certain day.

Option (D) is the correct option.

As we know that degree of freedom is 1 less than the size of sample.

So, Mathematically, it is expressed as below:

So, Degree of freedom would be

v=n-1\\\\v=8-1\\\\v=7

Hence, Option 'c' is correct.
