Answer: x = 15

Step-by-step explanation:

Vertical angles are equal so we can set 47 = 3x + 2

Now just solve the equation for x

47 = 3x + 2

Subtract 2 from each side

45 = 3x

Divide both sides by 3

15 = x

What is the slope of the line with the equation y-3=-1/2(x-2)?

torisob [31]

Answer: $-\frac{1}{2}$

Step-by-step explanation:

$y -3 = -\frac{1}{2}(x-2)$

Write as slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.

$y-3=-\frac{1}{2}x + 1$

$y = -\frac{1}{2}x+4$

Therefore, the slope is $-\frac{1}{2}$ .

If the coefficient of correlation is .8, then the percentage of variation in the dependent variable explained by the estimated r

Olegator [25]

Answer:

64%

Step-by-step explanation:

The percentage of variation in the dependent variable explained by the estimated regression is calculated with the coefficient of correlation as follows:

First, square the coefficient of correlation: 0.8^2 = 0.64

And then, multiply this result by 100, so that, it is expressed as a percentage: 0.64*100 = 64%
