99 points! plz lisa is not sure if m causes n, n causes m, or neither. in an attempt to come to a conclusion, she first plotted m on the x-axis, n on the y-axis, and used the linear regression feature of her graphing calculator. when she did this, she got a correlation coefficient (r) of 0.962 and a line with a slope of 2.3. she then plotted n on the x-axis, m on the y-axis, and used the linear regression feature of her graphing calculator. when she did this, she got a correlation coefficient (r) of 0.962 and a line with a slope of 0.4. which conclusion is the most valid? a) m causes n. b) n causes m. c) m might cause n, or n might cause m. d) m doesn’t cause n, and n doesn’t cause m.

The answer is C. M might cause N, N might cause M

Step-by-step explanation:

The slope of the line produced by Lisa’s graphing calculator has nothing to do with whether m causes n, n causes m, or neither (One exception to this would be if the slope were 0. This would imply no correlation, and thus, no causation.) Since the correlation coefficient (r) is 0.962 in both cases, a correlation probably exists between m and n. However, correlation does not imply causation, nor does it imply a lack of causation. Therefore, the conclusion of Lisa’s that is the most valid is m might cause n, or n might cause m.

$12. that is my answer.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
