1) At (solid) = 2160 cm2

Vt (solid) = 7128 cm3

P (solid) = 3564 g

2) x = -12

3) Mean = 121: 25 = 4.84

Fashion = 3

Median = 3

4)
- You get a line through The origin of the axes
- Proportionality is direct because the two variables space and time are directly proportional
- The speed ratio as distance traveled / time spent is the constant of proportionality
K = y / x, v = s / t ( because the speed is constant v = 15 km / h)
