- Approaching the month of Ramadan, PT Prima Sehat predicts that there will be an increase in demand for fresh meat. For this reason, the company seeks to optimize this moment for increasing company profits. One of the efforts made is to maximize income from the livestock sector by calculating the optimization of animal food. The raw material for animal feed used today is suspects and kala, at a price of Rp. 20 and Rp. 30 per kg.Each animal feed must contain alpha elements not less than 30 units and gamma 120 units, and beta elements at most 280 units. The composition of feed consisting of suspects and kala is at most 8 to 1. From the information received, it is known that the composition per kg of suspect consists of 6 alpha units, 20 units of Beta and 10 units of gamma. Whereas per kg of Kala contains 3 units of alpha composition, 40 units of Beta and 40 units of Gama. The company only provides Sangka as much as 8 kg per process Please use the linear graph method program to solve the…solve the problem with the second partial derivative test or with Lagrange's method: Find the volume of a rectangular box with maximum volume if the surcafe is 96cm2 please show full and complete procedure HANDWRITTEN onlyTake two numbers x and y at random between the interval (0,1) and find the probability that the product of the two numbers is less than 0.25. my answer is 0.25+ ln2 /2 ,but i am not sure ,please give the detailed steps,thanks.
- Calc 2 Substitute the attached integral problemThe manufacturer of hardness testing equipment uses steel-ball indenters to penetrate metal that is being tested. However, the manufacturer thinks it would be better to use a diamond indenter so that all types of metal can be tested. Because of differences between the two types of indenters, it is suspected that the two methods will produce different hardness readings. The metal specimens to be tested are large enough so that two indentions can be made. Therefore, the manufacturer uses both indenters on each specimen and compares the hardness readings. Construct a 95% confidence interval to judge whether the two indenters result in different measurements. Note: A normal probability plot and boxplot of the data indicate that the differences are approximately normally distributed with no outliers. Click the icon to view the data table. Construct a 95% confidence interval to judge whether the two indenters result in different measurements, where the differences are computed…The manufacturer of hardness testing equipment uses steel-ball indenters to penetrate metal that is being tested.
