Which associations best describe the scatter plot? select each correct answer. (a) linear association, (b) positive association, (c) negative association, (d) nonlinear association

The correct answer is (C) Negative association

Explanation:

A scatter plot is a type of graphic used to depict the relationship between two variables or factors using points in a vertical and horizontal axis. In this context, negative association or correlation occurs when the two variables do not increase or decrease together but one increases and the other decreases or vice-versa. This occurs in the scatter plot presented because the number of individuals infected (y-axis) decreases over time (x-axis). This means the first variable decreases while the second variable increases and therefore there is a negative association.

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
