We now that the probability that one randomly selected car will crash in the year is <span>0.047800478. If a family has three cars, this means that the probability that some of their car will crash in the next year is : 3 * the probability that one randomly selected car will crash = 3 * </span><span>0.047800478. = 0.143401434</span>
20.9 ft This is a right triangle trigonometry question because N is 90 degrees. MN is adjacent to M and LM is the hypotenuse. Adjacent any hypotenuse use the cosine function. plug in known values switch cos(20) and x using the products property plug into calculator to get 20.9 ft
