Answer: D. minimizes the sum of the squared residuals

Step-by-step explanation: The ordinary least square method is often used in locating the trendine which best fits a graphical linear model. The best is one in which the sum of the squared residual is smallest. The residual refers to the difference between the actual and the predicted points. The sum of the squared differences is obtained and the trend line is positioned where the residual is minimum. Choosing a OLS, and minimizing the sum.of the squared residual, the error difference between the predicted and actual score is minimized or reduced, hence, improving the prediction accuracy of our model.

Which lengths can be used, directly or indirectly, to calculate the volume of the hexagonal right pyramid? Select three options.
grigory [225]

Answer:

See below.

Step-by-step explanation:

The volume is 1/3 * height * area of the base so we need the height and this area to find the volume. Note: if we join the point S to each of the vertices of the base we get 6 equilateral triangles so knowing the length of a side of the base we can find the area of the base.

The following lengths can be used:

XY and ST  We can get the area of the base knowing the length of XY and ST is the height.

VU and TW. From VU we can get the area of the base and the length of SW and from the length of TW and SW we can get the height.

TX and WX . From WX we can get the area of the base and the length of SX and from TX and SX we can find the height.

The answer to number 8
dmitriy555 [2]
The number 8 is a rational, even and positive integer. It is also referred to as a composite number, or a nonprime, since it is divisible by factors other than 1 and itself. The number 8 also contains the factor pairs of 1 and 8 and 2 and 4. Another related characteristic of the factors of 8 is that its distinct prime factor is 2, which is the prime number that divides 8 evenly.

Take a look at the figure. What are the coordinates of the point labeled A in the graph shown?
Misha Larkins [42]

Answer:

(2,-2)

Step-by-step explanation:

Point A is 2 units to the right of the origin so the x coordinate is 2

It is also 2 units down so the y coordinate is -2

The point is (x,y) so A = (2,-2)
