Suppose you are the purchasing manager for a company that manufactures scanners and other computer peripherals. Your vendor for scanner motors is now offering "quantity discounts" in the form of instant rebates and lower shipping charges as follows. Quantity Net Price Rebate Shipping 1-500 motors $16 none $1.50 501-1,000 motors 16 $1.30 1.10 1,001-2,000 motors 16 1.90 0.80 (a) Calculate the cost of the motors, including shipping charges, for each category (in $). 1-500 motors 24 501-1,000 motors 2$ 1,001-2,000 motors 2$ you usually purchase 400 motors per month, what percent would be saved per motor by ordering 800 every two months? Round to the nearest tenth of a percent. (b) If % (c) What percent would be saved per motor by ordering 1,200 every three months? Round to the nearest tenth of a percent. %
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
Apologies. We only answer one question or 3 subparts at a time. We will answer the first three subparts a b and c as the exact one wasn't specified. Please submit a new question specifying the one you'd like answered.
For 1-500 motors,
Net price = $16
(a)
Rebate = None
Shipping = $1.50
Cost of the motors including shipping charges is:
For 501-1000 motors,
Net price = $16
Rebate = $1.30
Shipping = $1.10
Cost of the motors including shipping charges is:
