Consider the population of all 1-gal cans of dusty rose paint manufactured by a particular paint company. Suppose that a normal distribution with mean μ = 5 ml and standard deviation σ = 0.2 ml is a reasonable model for the distribution of the variable x = amount of red dye in the paint mixture. Use the normal distribution model to calculate the probabilities below. (Round all answers to four decimal places.)(a) P(x > 5) =(b) P(x < 5.4)=(c) P(x lteq.gif 5.4) =(d) P(4.6 < x < 5.2) =(e) P(x > 4.5) =(f) P(x > 4) =

Consider the following problem: A box with an open top is to be constructed from a square piece of cardboard, 3 ft wide, by cutting out a square from each of the four corners and bending up the sides. Find the largest volume that such a box can have. Let x denote the length of the side of the square being cut out. Let y denote the length of the base.(a) Draw several diagrams to illustrate the situation, some short boxes with large bases and some tall boxes with small bases. Find the volumes of several such boxes. (Do this on paper. Your teacher may ask you to turn in this work.)(b) Draw a diagram illustrating the general situation. Introduce notation and label the diagram with your symbols. (Do this on paper. Your teacher may ask you to turn in this work.)(c) Write an expression for the volume V in terms of x and y.V =(d) Use the given information to write an equation that relates the variables. (Do this on paper. Your teacher may ask you to turn in this work.)(e) Use part (d) to write the volume as a function of x.V(x) =(f) Finish solving the problem by finding the largest volume that such a box can have.V = ft3

The average assembly time for a Ford Taurus is μ = 38 hrs. An engineer suggests that using a new adhesive to attach moldings will speed up the assembly process. The new adhesive was used for one month. During that month, the average assembly time for 36 cars was = 37.5 hours with a standard deviation s = 1.2 hours. Use α = 0.01. Based on the calculated P-value will you reject or fail to reject the null hypothesis? Select one: a. reject the null hypothesis / data is significant b. fail to reject the null hypothesis c. cannot be determined

Mia removes the plug from a trough to drain the water. The volume, in gallons, in the trough after it has been unplugged can be modeled by the expression 10x2 −19x + 6, where x is time in minutes. Choose the appropriate form of the expression that would reveal the time in minutes when the trough is empty. 10(0)2 − 19(0) + 6 10(x − 6)2 − 1 10(x − 1)2 − 6 (5x − 2)(2x − 3)
