1) find the mean,
   20+10+30+20+50+30+40+20/8= 27.5
2) Find the distance of each value from that mean
   20- 7.5
   10- 17.5
   30- 2.5
   20-7.5
   50- 22.5
   30- 2.5
   40- 12.5
   20- 7.5
3) Find the mean of those distances
   7.5+17.5+2.5+7.5+22.5+2.5+12.5+7.5/8=10

The Mean absolute deviation for this data set is 10.

What is an equation of the line that passes through the point (3,-1) and is parallel to the line 5x+3y=6

777dan777 [17]

Answer:

$y=-\frac{5}{3} x+4$

Step-by-step explanation:

Since the line we are trying to study is parallel to the one given by the standard equation 5x + 3y = 6, it needs to have the same slope as this given line has. Let's write then this equation in slope-intercept so we can find what the slope is :

$5x+3y=6\\3y=-5x+6\\y=-\frac{5}{3} x+\frac{6}{3} \\y=-\frac{5}{3} x+2$

Then the slope of our line must also be "-5/3" in order to be parallel to the given line.

Now, since we also know a point (3, -1) through which the new line should go, we use the point-slope form of a line:

$y-y_0=m(x-x_0)\\y-(-1)=-\frac{5}{3} (x-3)\\y+1=-\frac{5}{3} x+5\\y=-\frac{5}{3} x+4$

If the coefficient of determination is 0.233, what percentage of the variation in the data about the regression line is explaine

ddd [48]

We need the coefficient of determination definition

The coefficient of determination (R²) is a number between 0 and 1 that measures how well a statistical model predicts an outcome. You can interpret the R² as the proportion of variation in the dependent variable that is predicted by the statistical model

So if we have a coefficient of determination of 0.233 we multiply by 100 to get the percentage

Answer: 23.3%
