Answer:
The degrees of freedom, Df = The number of bags produced on Monday - 1
Step-by-step explanation:
The number of degrees of freedom is the limiting number of values that are logically not influenced by other values such that they are capable of having variation
The degrees of freedom = The sample size - 1 = N - 1
Therefore, the degrees of freedom, Df = The number of bags produced on Monday - 1
The given formula 
Solve for y means we have to make y alone
\\
Add -10 on both sides, we get

As there is multiplication sign between r and y so to solve for y, divide both side by r

Answer:
Salim can simplify that and the answer will be 
Step-by-step explanation:
This is because of the law of multiplying powers, which states that you can add the exponents if the base is the same. So, you just add m and n and put that as the exponent and you will have the answer.
Answer:
infinite
Step-by-step explanation:
If you multiply all factors in the secon eqation by 4, you will get the first eqation.
Therefore for any value of x you can find y, thus having an infinite number of x,y pairs
