The table shows the weight of a dog in pounds at various ages in months. what values should be entered for x and y into a regression calculator to find the equation of the trend line? x: 3, 4, 6, 8, 9, 12 y: 2, 5, 7, 10, 11, 15 x: 3, 4, 6, 8, 9, 15 y: 2, 5, 7, 10, 11, 12 x: 2, 5, 7, 10, 11, 15 y: 3, 4, 6, 8, 9, 12 x: 2, 5, 7, 10, 11, 12 y: 3, 4, 6, 8, 9, 15

The Regression line is that line , which passes through all the points , through a single point , or none of the points.

Here, the table is about ,weight of a dog in pounds at various ages in months.

The ratio of Weight at different stages,of months should be proportional.

So, if you look at option (1) , the ratio of x to y in three cases are same that is

It means Regression line is Passing through three points, means Dog's weight  at three different stages of month are same.and in other tables the ratio are not equivalent.

So, Table 1, that is option 1

is true.

x: 3, 4, 6, 8, 9, 12

y: 2, 5, 7, 10, 11, 15

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

the answer is 31.27mph
