  • Question on Linear programming?

    Pearl s company has just received and urgent order for its bathroom cabinets,which it makes in two styles,standard and deluxe. The order is for at least 100 bathroom cabinets of either variety, including at least thirty of the deluxe style.

    The standard model takes two hours of assembly time and has variable costs of P40,whereas de luxe takes 5 hours of assembly time and has variable costs of P60.

    There are 400 hours in total available for assembly.the equipment can be used to assemble either style of cabinet in any combination.

    Other reasons dictate that atleast as many standard cabinets as deluxe cabinets must be made.

    The company wishes to minimize its variable costs of production on this special order.

    Required

    A.formulate this problem as a linear programming problem

    b.graph the constraints,shading the unwanted region

    c.recommend the best product mix for the company.what is the variable cost incurred.

    My major challenge is the objective statement and constraints

  • Explain this phrase" coffee consumption significantly decreases all-cause mortality"?

    Here is the full write up incase you need it

    In women, coffee consumption significantly decreases all-cause mortality, apparently decreasing somewhat linearly to a relative risk of approximately 0.85 for those drinking 3 cups per day compared to those who consume no coffee, but the relative risk then remains almost the same for up to 6 cups per day, according to a large prospective cohort study in 1993.[4] In men, these beneficial effects were not as great, in fact with an increased risk for those drinking approximately one cup every other day compared to those drinking none, but yet having a significant trend towards less mortality for those who drink more than 2 cups per day compared to those who drink none.[4] Results were similar for decaffeinated coffee.[4] An inverse association between coffee consumption and total and cause-specific mortality was also found in a 2012 analysis of data from the National Institutes of Health–AARP Diet and Health Study.[2]

  • I love you turned me off. what should I do next?

    The waitress at a bar I usually goto is very hot(I can say she is a 9/10). The last time I went there with a friend of mine and a random guy(less call the random guy madkid) I met from facebook to have a bear, I told them I like the waitress and would like to date her. I asked her for her number and she pretended not to want to give it to me but she did after I told her it was "No big deal". After our drink and we were about to leave, madkid paid the bill and he needed a change. It about $0.25 so I told him, hey leave the change let's hit the run. But he instead on collecting it, my friend and I left the bar and started strolling a way. After a 5 minute wait for him, he came back telling us he had bought her a drink, collected her number and arranged to meet her the next friday. (Honestly, I was sad, he just went behind my back. But I guess that's what you get when u hang out with random guys from facebook)

    The whole thing passed and I deleted her number, since the guy called dips first. Just yesternite, something shocking happend, he went to the bar, talked to her but she kept asking about me and why I didn't call her. She even asked for my number and told the guy she is not interested in dating him.

    Later that night she called me and told me who she was and asked why I didn't call. I told her honestly, you were hit off with madkid so I didn't want to get in the way. She told me she just turned him down and asked me if she could come over to my place( it was about 11pm dat nite and I have a room mate so I said no)

    In the next hour she had me up on facebook, twitter, gtalk and oda social networks.

    At first I was loving it until she sent on facebook " hey joe, I love you so much and want you to be my boyfriend. Do you feel the same way about me?". I didn't say no or yes. She kept insistin a persuading me to say I love her but I didn't. Now she said I should think about it and let her know. Any advice? Should I date her, or is she just plain needy
