The management of white industries is considering a new method of assembling its golf cart. the present method requires a mean time of 42.3 minutes to assemble a cart. the mean assembly time for a random sample of 24 carts, using the new method, was 40.6 minutes, and the standard deviation of the sample was 2.7 minutes. using the 0.10 level of significance, can we conclude that the assembly time using the new method is faster

Determine whether the following statements are true and give an explanation or counterexample. bold a. when using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. bold b. if a region is revolved about the y-axis, then the shell method must be used. bold c. if a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y.

For the equations below which statement is true ? -2x=14 6x=-42
