The correlation between distance (in kilometers) and airfare (in dollars) is 0.8. If we were to change the distance to be measured to miles ( all the values in the distance will therefore be divided by 1.61) , what effect will this have on the correlation?

Which transformations could be performed to show that aabc is similar to aa"b"c"? a reflection over the x-axis, then a dilation by a scale factor of 3 a reflection over the x-axis, then a dilation by a scale factor of 1/3 a 180° rotation about the origin, then a dilation by a scale factor of 3 a 180° rotation about the origin, then a dilation by a scale factor of 1/3
