Answer:

The value of x from the equation is 100. Thus, Mrs. Gleason should work for 100 hours per month.

Step-by-step explanation:

To answer this item, we let x be the number of hours per month that Mrs. Gleason should work. The total budget is equal to sum of the amount acquired by Mr. Gleason and Mrs. Gleason. The equation that would express this is,

4,500 = 900(4) + 9x

The value of x from the equation is 100. Thus, Mrs. Gleason should work for 100 hours per month.

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, r, will be to either +1 or -1 depending on whether the relationship is positive or negative, respectively.

If the value of the correlation coefficient is 0 < r < 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 r, 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 r is closer to 1, which implies a strong positive relationship between two variables. My estimate is that r = 0.8.

Therefore, the correct answer is Strong Positive association.
