Suppose the line of best fit is being found for some data points that have an r-value of 0.876. if the standard deviation of the x-coordinates is 5.559, and the standard deviation of the y-coordinates is 7.163, what is the slope of the line to three decimal places?

1.129

Step-by-step explanation:

In statistics, the slope of the line is given by :-

,

Now, the slope of the line will be :-

Hence, the lope of the line to three decimal places =1.129

step-by-step explanation:

15   3/4 / 3 = 5   1/4

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
