I think the correct answer from the choices listed above is the second option. The conclusion saying playing violin causes students to get better grades is a reasonable conclusion. This is because the correlation coefficient is above 0.5, so that implies causation. Hope this answers the question.
Answer:
x-int=-8, y-int=2,-4
Step-by-step explanation:
for the x-int
you set x to 0 then solve the equation to get -8
for the y-int
you set y(or in this case f(x)) to 0 then solve. You solve this by spilting this into 2 linear equations; x-2=0 and x+4=0, then you solve them both to get the two y-intercepts, 2 and -4
2.5*7 = 17.5. If it's easier for you, multiply 2.5 by 5 then add 2.5*2.
The answer is that they all are Latin Jazz artists
