Answer: 0.12
Step-by-step explanation:
The expected number of accidents is a weighted average of the potential number of accidents and their probabilities:
= (0 * 0.935) + (1 * 0.03) + (2 * 0.02) + (3 * 0.01) + (4 * 0.005)
= 0.12
1=9/12
1=3/4

Given the distance function d(t) = 0.8t^2, we must derive the formula to get the formula for velocity. The first derivative of a distance function gives the velocity because it shows how the variable (distance) changes over a another variable which is usually time. Following the same line of thought, the second derivative gives the acceleration.
dt = 2(0.8)t = 1.6t = 1.6(10) - 1.6(5) = 8 m/s
41 increased by d is 41+d
