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.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
