a.
the slope of the line is negative, but the data set has a positive correlation.
b.
the slope of the line is positive, but the data set has a negative correlation.
c.
the y-intercept of 107 will not produce a line that "centers" the scatter plot.
d.
the data set has no correlation and cannot be accurately represented with a linear equation.

D.

Explanation:

The data set has no correlation and cannot be accurately represented with a linear equation.

there seems to be no relation between the numbers

if you know the x value, you can't really guess what its y value is (no correlation)

im not intirely sure but i think the anwser is d relative humidity

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
