- A biologist has placed three strains of bacteria (denoted I, II, and III) in a test tube, where they will feed on three different food sources (A, B, and C). Each day 400 units of A, 500 units of B, and 600 units of C are placed in the test tube, and each bacterium consumes a certain number of units of each food per day, as sh own in Table . How many bacteria of each strain can coexist in the test tube and consume all of the foodA forest consists of two types of trees: those that are 0-5 ft and those that are taller than 5 ft. Each year, 40% of all 0-5-ft tall trees die, 10% are sold for $10 each, 30% stay between 0 and 5 ft, and 20% grow to be more than 5ft. Each year, 50% of all trees taller than 5ft are sold for $40, 20% are sold for $20, and 30% remain in the forest (continue growing). If a tree (less than 5 ft) is planted, what is the expected revenue earned from that tree ?

Basically, a specific screen is tested once using the two inspection devices. Device 1 can detect the presence of defects 99.3% of the time, whereas Device 2 can detect defects 99.7% of the time. Assume that the 2 devices are operating independently from each other. One day, four defective screens were sent for inspection. Let X represent the number of screens that will be correctly tagged as defective by Device 1, while Y represents the number of screens that will be correctly tagged as defective by Device 2. Are X and Y independent? explain
- Even though you have no symptoms, your doctor withes to test you for a raredisease that only 1 in 10,000 people of your age contract. The test is 98%accurate, which means that, if you have the disease, 98% of the times the testwill come out positive and 2% negative. Also, if you do not have the disease, the test will come out negative 96% of the time and positive 4% of the time. You take the test and it comes out positive. What is the probability that you have the disease?How is the hatching of water python eggs influenced by the temperature of the snake's nest? Researchers placed 104104 newly laid eggs in a hot environment, 5656 in a neutral environment, and 2727 in a cold environment. Hot duplicates the warmth provided by the mother python. Neutral and cold are cooler as when the mother is absent. The results: 7575 of the hot eggs hatched, along with 3838 of the neutral eggs and 1616 of the cold eggs.26 Make a two‑way table of "environment temperature" against "hatched or not." Fill in the values ?-?�-� in the answer boxes provided. Give your answers as whole numbers. Temperature Cold Neutral Hot Hatched ? ? ? Did not hatch ? ? ? ? =Here's a problem that was used as the basis of a television show to illustrate the difference between the way a human mind approaches such a problem and the brute-force approach of a computer that finds the solution by trying all possible 40,320 different arrangements of the digits. Place the digits from 1 though 8 in the eight circles shown in the diagram, but with this restriction: no two digits next to each other in serial order may go in circles that are connected by a direct line. (For example: if 2 is placed in the top circle, neither 1 nor 3 may be placed in any of the three circles in the horizontal row beneath it because each of these circles is connected to the top circle by a direct line.) There is only one solution.
