Why do we square the residuals when using the least-squares line method to find the line of best fit?

Mathematics

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.

A child bus ticket costs $0.40 and an adult’s ticket costs $0.70. A group of 11 individuals pays $5.90 for their fare.
oee [108]
Here we have a system of equation like this:
A+B=11\\&#10;0.4A+0.7B=5.9
from the first equation we get:
A=11-B
Substitute in the second equation we get:
0.4(11-B)+0.7B=5.9\\4.4-0.4B+0.7B=5.9\\0.3B=1.5\\B= \frac{1.5}{0.3}=5
Substitute i the first equation again we get:
A=11-B=11-5=6
We deduce that:
A > B A is bigger than B.

Classify the triangle with 9, 15, 19 as an acute right obtuse or not a triangle
Novosadov [1.4K]

Answer:

Hence the correct option is the last one . The triangle is an obtuse angled triangle.

Step-by-step explanation:

i) the sum of any two sides added together is greater than the third side hence this is a triangle.

ii) it is<em><u> not</u></em> a right angled triangle as \sqrt{9^{2} + 15^{2} } \neq  19 and \sqrt{9^{2} + 15^{2} } <  19

iii) the triangle is not acute from ii) above

iv) the triangle is an obtuse triangle from ii) above.

Evan’s family drove to a theme park for vacation.
zhuklara [117]

Answer:

They drove 150 miles on the third day

They drove 50 miles per hour so if you multiply that by 3 (since they drove 3 hours on the third day) you would get 150 miles.
