We square the residuals when using the least-squares line method to find the line of best fit because we believe that huge negative residuals (i.e., points well below the line) are just as harmful as large positive residuals (i.e., points that are high above the line).
<h3>What do you mean by Residuals?</h3>
We treat both positive and negative disparities equally by squaring the residual values. We cannot discover a single straight line that concurrently minimizes all residuals. The average (squared) residual value is instead minimized.
We might also take the absolute values of the residuals rather than squaring them. Positive disparities are viewed as just as harmful as negative ones under both strategies.

The answer is -9 because you have to multiply the two numbers.
Answer:
6
Step-by-step explanation:
Total number of subsets is given as

But the subset of a set consists of the proper subsets, an empty set and the set itself.
Total number of subsets are 64
Therefore,


Comparing both sides

Answer:
total amount = n (d-18)
total amount = dn - 18n
Step-by-step explanation:
given data
pay = $18 less than the original price
originally cost = d dollars
sell = n games
solution
we take original price paid for the game = d
and they will pay $18 less than the original price
so that can we say
d -18
and
when sold n games than the cost of n used games will be here
cost = n (d-18)
so it can express as
total amount = n (d-18)
total amount = dn - 18n
Answer:
f(6) = 1
Step-by-step explanation:
Function:
f(x) = -2/3x + 5
f(6) = -2/3(6) + 5
f(6) = -4 + 5
f(6) = 1
