Normal distribution. the lifetime of a certain type of automobile tire (in thousands of miles) is normally distributed with mu = 42 and sigma = 5. what is the probability that a randomly chosen tire has a lifetime equal to 45 thousand miles? for this problem we want just the answer. give up to 4 significant decimal places, and use the proper rules of rounding.

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
