Answer:

Strong positive correlation

Step-by-step explanation:

The given scatterplot, where the data points are sloping upward:

The stronger the association of the two variables, the closer the Pearson correlation coefficient, <em>r</em>, will be to either +1 or -1 depending on whether the relationship is <em>positive</em> or <em>negative</em>, respectively.  

If the value of the correlation coefficient is 0 < <em>r</em> < 1 then there is a positive linear trend and the data points are scattered around the line of best fit; the smaller the absolute value of <em>r, </em>the less well the data can be visualized by a single linear relationship. The closer the value of r to 0 the greater the variation around the line of best fit.

In the attached screenshot, where I've drawn a line across the graph: it shows that the data points are clustered around the line. It is easier to estimate that the value of <em>r </em>is closer to 1, which implies a strong positive relationship between two variables. My estimate is that <em>r</em> = 0.8.

Therefore, the correct answer is Strong Positive association.

What is 3/4 doubled? Is it 6/8 or 1 2/4?
Amanda [17]

Answer:

1 2/4

Step-by-step explanation:

3/4 doubled is 2(\frac{3}{4} )=\frac{3}{2}

Now, \frac{6}{8} =\frac{3}{4} on simplification.

1 \frac{2}{4} =\frac{6}{4} =\frac{3}{2}

Therefore,

3/4 doubled is 1 2/4

saveliy_v [14]
8/24 = x / 48
cross multiply
(24)(x) = (8)(48)
24x = 384
x = 384/24
