A. The value of r = -0.83 means that there is a good negative correlation between the analyzed variables. In option A, the relation is positive, then it is not the correct answer. In option C, the values are highly dispersed, then the absolute value of r = 0.83 seems too high for this case. Therefore, Option B seems to be the correct option.

B. The equation y = 0.6x + 1.75 has a positive slope. The only graph with a line of best fit whit a positive slope is option A.

Find the value of x in the equation: <br> x^2 + 4 = 12

jonny [76]

Answer:

$\sqrt{8} = 2 \sqrt{2}$

Step-by-step explanation:

In the equation we must first move 4 to the other side and change its sign

x^2 + 4 = 12

x^2 = 12 - 4

x^2 = 8

Then we find x:

x =

$x = \sqrt{8} = \sqrt{2 \times 2 \times 2} = \sqrt{ {2}^{2} \times 2 } = 2 \sqrt{2}$
