Which data set has the smallest IQR?

hiking down a winding trail.

step-by-step explanation:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.

the answer is b
