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.

(05.02)An artist is designing a kite like the one show below. Calculate the area to determine how much material she will need to
artcher [175]

Answer:

161.5 in.^2

Step-by-step explanation:

Since you don't have a figure, from your description, I understand that the base of each small upper triangle is 8.5 inches. That means that each small triangle on top has a base of 8.5 inches and a height of 5 inches, and each small triangle below has a base of 8.5 inches and a height of 13 inches. My calculations below are base don this understanding.

The area of a kite is

A = (Bb)/2

where B and b are the lengths of the diagonals.

The diagonals have lengths:

B = 13 in. + 6 in. = 19 in.

b = 8.5 in. + 8.5 in. = 17 in.

A = (Bb)/2

A = (19 in. * 17 in.)/2

A = (323 in.^2)/2

A = 161.5 in.^2

Problem 6-27 A project manager is creating the design for a new engine. He judges that there will be a 50-50 chance that it will
ale4655 [162]

Answer:

Probability = 0.275

Step-by-step explanation:

There are two possible ways for his design to be approved: Being a high-energy engine (H) and being approved or a low-energy energy (L) and being approved.

It is known that there is a 50-50 chance of the engine being high or low-energy.

The probability of approval for each type of engine (E) is given by:

P(E) = 0.5*A(E)

Where A(E) is the approval rate for each engine.

Therefore, the probabilities of approval for each type of engine are:

P(H) = 0.5*0.25\\P(H) =0.125\\P(L) = 0.5*0.30\\P(L) =0.150\\

The total probability of approval is the sum of both low and high-engine probabilities;

Probability = P(H)+P(L) =0.125+0.150\\Probability = 0.275
