The Crazy Nut Company wishes to market two special nut mixes during the holiday season. The Fancy Mix contains 0.5 pound of peanuts and 0.5 pound of cashews. The Deluxe Mix contains 0.6pound of peanuts, 0.2 pound of cashews and 0.15 pound of almonds. Fancy Mix sells for $12 per can and Deluxe Mix sells for $16 per can. The data pertinent to the raw ingredients appear in the table. The Crazy can sell all cans of either mix that it produces, but wants to keep the production quantity of Fancy Mix at least twice as many as Deluxe Mix. Formulate an LP model to determine how many of each mix to produce to maximize the total profit. Do not solve it. You can formulate as a spreadsheet model or an algebraic model. Define your decision variables (changing cells) clearly. Ingredient Amount Available (lb) Cost Per Pound (s) Peanuts 300 $1 Cashews 120 $3 Almonds 90 $4
Hi i’m in grade 12 Data Management and i need help with this practice question
The following data was collected to explore how the number of square feet in a house, the number of bedrooms, and the age of the house affect the selling price of the house. The dependent variable is the selling price of the house, the first independent variable (x1x1) is the square footage, the second independent variable (x2x2) is the number of bedrooms, and the third independent variable (x3x3) is the age of the house.

A ✩ The box-and-whisker plot below represents the length, in inches, of 20 trout caught at Raystown Lake in one weekend. 4466619/varlants/5145485/take/5/ 10 Length of Trout (inches) H 15 20 H 25 30 How many trout were less than 20 inches long? Hint: 20 inches is the upper quartile of the box-and- whisker plot. So, 75% of the trout were less than 20 inches long. To find the answer: multiply the percentage (75%) x 20 (the number of inches) We use 75% because that is the Q3 in the data. 25% would be our Q1 and 50% is the median (or Q2).

The publisher of a sports magazine plans to offer new subscribers one of three gifts: a sweatshirt with the logo of their favorite team, a coffee cup with the logo of their favorite team, or a pair of earrings also with the logo of their favorite team. In a sample of 500 new subscribers, the number selecting each gift is reported below. At the 0.05 significance level, is there a preference for the gifts or should we conclude that the gifts are equally well liked? Gift Frequency Sweatshirt 183 Coffee cup 175 Earrings 142 H0: πs = πc = πe H1: The proportions are not equal. a. State the decision rule. Use 0.05 significance level. (Round your answer to 3 decimal places.) b. How many degrees of freedom are there? c. Compute the value of chi-square. (Negative amounts should be indicated by a minus sign. Round "fe" and "fo – fe" to 2 decimal places. Round (fo – fe)2/fe to 4 decimal places. Round χ2 to 4 decimal places.)
