Answer:
The highest number that divides each of the two or more numbers is the HCF or Highest Common Factor.
Step-by-step explanation:
Example: What is the HCF of {12,42,14}
Answer: The HCF is 2 as the biggest number they can all be divided by is 2. {12,42,14} = {2^2*3,2*3*7,2*7} The factors in each number is 2.
Josie has a cord that is 9 feet long
If she wants to cut it into 11 pieces then each piece will be (9 ÷ 11) which is 0.81
Answer:

And the real value for this case is y=14. The residual is defined as:

Replacing we got:

And the best answer would be:
-2
Step-by-step explanation:
For this case we know that the best fit line for the relationship between x and y is given by:

And we know that an individual in the dataset has a score of 10 on the x-variable and a score of 14 on the y-variable. So then we can find the estimated value like this:

And the real value for this case is y=14. The residual is defined as:

Replacing we got:

And the best answer would be:
-2
