The solution set for -18 < 5x-3 iso-3х3< xо-3хo3 > x

True or false: a fitted model with more predictors will necessarily have a lower training set error than a model with fewer predictors.

Performance bicycle company makes steel and titanium handle bars for bicycles. it requires approximately 1 hour of labor to make one handle bar of either type. during the most recent accounting period, barr company made 7,700 steel bars and 2,300 titanium bars. setup costs amounted to $35,000. one batch of each type of bar was run each month. if a single company-wide overhead rate based on direct labor hours is used to allocate overhead costs to the two products, the amount of setup cost assigned to the steel bars will be:
