An airplane tries to fly due north at 100 m/s but a wind is blowing from the west at 30 m/s. what heading (angle and direction) should the plane take to go due north in spite of the wind?

Angle of wind from west = 45°
x-component of wind:
Wx = 30cos(45)
= 21.1 m/s

The x component of the plane's speed should cancel this while the y component should remain 100 m/s

Py = Psin(∅)
100 = Psin(∅)
P = 100/sin(∅)

Px = Pcos(∅)
P = 21.1/cos(∅)
100/sin(∅) = 21.1/cos(∅)
tan(∅) = 100/21.1
∅ = 78.1° north from the west direction.

No, Micah is not correct. Since there are equal numbers of people in each group who drive and who do not drive, the relative frequency for each is 50%. Because the relative frequencies are the same, there is no association between the variables.
