Suppose that there were a strong correlation between the variables gand h.
which of these is a true statement?
o
a. gmust not cause h.
b. gmust cause h.
o
c. h must cause g.
o d. gmay cause h.

G may cause H.

Step-by-step explanation:

Correlation between variables does not imply casuality, since there could be a third variable which is the cause of both ( for example, the color of hair and the blood pressure might be correlated because the variable Age of the person causes white hair and high blood pressure when the person is old ). Correlation just means that a variable on average increases when the other one does.  

G may cause H

Step-by-step explanation:

I just did the test right now and I got it correct :)

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21
