During the trip, the Morales family drove on several different highways. Gabriela and Luis noticed that sometimes the mile markers were increasing, and other times the mile markers were decreasing. On one highway, Gabriela noticed that they passed mile marker 123 at 1:00. She then saw that they reached mile marker 277at 3:00. Since Mr. Morales was driving at a constant speed, their mile-marker location over time can be represented by a line where the time in hours is the independent variable and the mile marker is the dependent variable. The points (1,123) and (3,277) are two points on this line.What is the value of the slope of this line? Enter your answer as the correct value, like this: 42If your answer is a fraction, use the / symbol. For example, if your answer is 314, enter your answer like this: 3/14

Select all the correct answers.An architect is designing a swimming pool with a base in the shape of a right triangle. According to the architect, the pool’s depth should be 6 feet less than its length, x, and its width should be 8 feet less than its length. The volume of water in the pool cannot exceed 1,680 cubic feet. Which statements about the pool are true?The water level in the pool cannot exceed 14 feet.The water level in the pool cannot exceed 20 feet.The inequality x3 − 14x2 + 48x − 1,680 ≥ 0 can be used to find pool’s length.The inequality x3 − 14x2 + 48x − 1,680 ≤ 0 can be used to find pool’s length.The inequality x3 − 14x2 + 48x − 3,360 ≤ 0 can be used to find pool’s length.

Your lumber company has bought a machine that automatically cuts lumber. The seller of the machine claims that the machine cuts lumber to a mean length of 6 feet (72inches) with a standard deviation of 0.5 inch. Assume the lengths are normally distributed. You randomly select 47 boards and find that the mean length is 72.15 inches. Complete parts (a) through (c).Use the standard Normal Table(a) Assuming the seller's claim is correct, what is the probability that the mean of the sample is 72.15 inches or more?____ (Round to four decimal places as needed.)(b) Using your answer from part (a), what do you think of the seller's claim?(c) Assuming the seller's claim is true, would it be unusual to have an individual board with a length of 72.15 inches? Why or why not?

Cantwell Associates, a real estate devel- oper,is planning tobuild a new apartment complex con- sisting ofone-bedroomunits andtwo- and three-bedroom townhouses. A total of192 units is planned,and the number of family units (two- andthree-bedroom town- houses)will equal the number of one-bedroomunits. If the number ofone-bedroom units will be three times thenumber of three-bedroomunits, find how many units of each typewill be in the complex.
