Answer:
m= -2 1/2
Step-by-step explanation:
First, let's put the equation into slope intercept form.
6x-15y=270
-15y=-6x+270
y=6/15x+270
For two lines to be perpendicular, their slopes must be opposite reciprocals.
m=-15/6 or m= -2 1/2
I believe the answer to this problem is C.<span />

Answer: There is a strong association between age and weight.
Step-by-step explanation:
The correlation coefficient (r) is used to describe the relationship between two variables.
If r lies between -1 to -0.5 or 0.5 to 1, then there is strong association between them.
Here, Variables: Age and weight.
correlation coefficient = 0.512
That means, there is a strong association between age and weight.
