In an experiment, we are measuring the following random variable: speed of vehicles as they pass a certain highway segment. It appears that this variable follows a normal probability distribution with the following properties: N(72, 42.25). What is the probability that a randomly selected vehicle on this highway segment is traveling at a speed of 80 mph or more? a. 11%
b. 8%
c. 20%
d. 13%
e. 25%
f. 22%
g. 17%
h. 5%

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
