6. A construction zone on a highway has a posted speed limit of 40 Kilometers per hour. The speeds of the vehicles passing through this construction zone are normally distributed with a mean of 46 kilometers per hour and a standard deviation of 4 kilometers per hour. Find the percentage of vehicles passing through this construction zone that are: a) exceeding the posted speed limit b) traveling at speeds between 50 and 57 kilometers per hour. 7. A machine at...

4. The function v(t), 0 S t 8, gives the speed (in feet/min) of a crawling beetle at time t minutes. a. What equation would you solve to determine when the bug is halfway to its destination? b. Suppose v(t) 20/(1+2)2. When is the beetle halfway to its destination? First determine from a graph whether this is before or after time t-4.

A swimmingpool have the volume 1000 m3. With the time
t = 0, the swimmingpool is empty. We fill in so much water into the
swimmingpool with constant speed v = 2,4 m3 per minute.
At the same time, it is leaking water out of the swimmingpool
simultaneous and the speed is at every moment proportional with the
volume of the water. The proportional constant is a =
3*10-3minute-1
