The value of y varies inversely with x. what is the value of k when y=12.7 and x=8? A. k=101.6
B. k=20.7
C. k=1.5875
D. k=0.6299

answer: its the third option.

step-by-step explanation:

i just took the test.

probably .5

i can on others if necessary.

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

i those same problems in math and dont know how to do them
