Answer:

a) May be used to predict a value of y if the corresponding x value is given

Step-by-step explanation:

In regression analysis, the vertical distance from the regression line to the data points can be minimized using the least square regression line.

Given the example of a least square regression equation:

y = ax + b

Where

a = slope

b = Y-intercept

If the value of x is known, the value of y may be predicted.

Option A is correct.

A least squares regression line may be used to predict a value of y if the corresponding x value is given

A number is 2/3 if another number. the sum of the numbers is 50. find the numbers
slava [35]

A number is 2/3 of another number.  Both added together equals 50.

One of these numbers consists of three parts, and the other consists of two of those three parts.  So, there are 5 equal parts in total.

Thus we need to divide 50 by 5.  50 divided by 5 equals <u>10</u>.

The first number, which has three parts, is 30.  The second number, which as two parts, is 20.

I hope this makes sense to you.  :D  Good luck in all your studies!

A fish tank has the shape of a rectangular prism. It has a length of 2 1/4 meters, width of 7/8 meters, and a height of 1 1/2 me
bazaltina [42]

volume = L x W X H

2 1/4 x 7/8 x 1 1/2 = 2 61/64 cubic meters

1 cubic meter = 1000 liters

2 61/64 = 2.953125

2.953125 * 1000 = 2,953.125 liters ( Round answer as needed )

How would we rewrite the equation of y = 1/3x -10 if we moved its graph down six units?
levacccp [35]

If you didn't change the slope of the line, but you moved it
down 6 units on the graph, then its y-intercept would become
6 less.  The equation of the new line would be ...

                  y = 1/3 x - 16 .
