The weights of cars passing over a bridge have a mean of 3,550 pounds and standard deviation of 870 pounds. Assume that the weights of the cars passing over
the bridge are normally distributed. Use a calculator to find the probability that the
weight of a randomly-selected car passing over the bridge is more than 4,000
pounds.
a) 30.42%
b) 50%
C) 69.58%
d) 39.34%

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
