mike created a scatter plot to show the masses and ages of several samples of a radioactive material.

which statement is true about the data shown in the scatter plot?

a. there is a nonlinear correlation between the masses and ages of the samples.

b. there is no correlation between the masses and ages of the samples.

c. there is a positive linear correlation between the masses and ages of the samples.

d. there is a negative linear correlation between the masses and ages of the samples.

the answer is d.

because the dots go in a general direction of negative. and because mass and age go along , so there has to be a correlation.

A. There is a nonlinear correlation between the masses and ages of the samples.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
