I am having trouble deciding what is true for these questions. I thought I had the right answers but they keep getting marked wrong. For Question 1, I chose option 2, as I though all the others to be false. For Question 4 I chose option 4, as I learned that the z-scores of the mean and standard deviation were always 0 and 1, respectively. For question 5 I chose option 4 as well. Which one of the following statements...

1. You are being hunted by a raptor. It corners you, and begins to charge, qt a velocity of 20 m/s. You have constructed a trap. It consists of a trip wire that will knock the raptor down and transfer all of its KE to a phaser rifle that requires 80 kJ of energy to fire directly at your foe. If the raptor has a mass of 150 kg, will the rifle gain enough energy to fire? a)no b)not enough...
