according to a Poisson process with an average inter-arrival time of 12 minutes. The time to complete a return for a customer is exponential distributed with a mean of 10 minutes. Based on this information‚ answer the following questions a. If you went to Judy‚ how much time would you allow for getting your return done? b. On average‚ how much room should be allowed for the waiting area? Lq= c. If Judy stayed in the office 12 hours per day‚ how many hours on average‚ per day‚ would she be busy? 12*5/6=10hr

thermoregulation Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Homeostasis is the ability to maintain a stable environment inside the body. For example‚ your body does things to maintain constant blood sugar levels and body temperature. 1. What are some things you do to stay cool on a hot day? Some things I do to stay cool is to drink water‚ wear less clothes and turn the fan/ air conditioner on at the location I am at. 2. What can you do to warm up on a cold day? On a cold

The Effect of Increasing Temperatures on the Enzyme Catalase Enzymes are proteins that help speed up chemical reactions inside your body and without enzymes‚ chemicals reactions in cells would be incredibly slow to a point where no activity at all takes place (Brawo press Inc‚ 2017). Enzymes speed up the chemical reactions by lowering the activations energy and they do this by binding substrates together in the correct orientation to react (Ernest Z‚ 2014). They are vital for life and serve a

Can tegu lizards maintain an elevated body temperature during their reproductive season? Experiment: Dr. Glenn Tattersall and a team of researchers in Rio Claro‚ Brazil studied changes in the heart rate and body temperature of tegu lizards (Salvator merianae)‚ by implanting lizards bred in captivity with specialized electronic chips. One group of lizard lived in an entirely outdoor environment for one year. Three other groups that were subjected to alternating indoor and outdoor environments over

1. There are more people in Shanghai than in New Zealand Like… 4 times more. According to the 2009 census‚ Shanghai has a population of about 19 million. In comparison‚ Statistics New Zealand’s population clock points at 4 million at the time of writing. Density-wise‚ Shanghai scores a whopping 3000/km2‚ 3 times higher than Auckland City‚ New Zealand’s most populous urban area. Although‚ both cities look like playgrounds when compared to those in the top 50 list… 2. The main language spoken in

Examples of extreme environments on Earth are hot geysers and oceanic thermal vents‚ Antarctic sea ice‚ and oxygen-depleted rivers and lakes. Organisms that have evolved special adaptations that permit them to live in extreme conditions are called "extremophiles."

The Effect of Temperature on Solubility By Aviraj Singh Rogers 2 Background: The solubility of most solid substances is generally said to increase as the temperature of the solvent increases. However‚ some substances‚ such as ytterbium sulfate‚ do the opposite. This can be explained through the Second Law of Thermodynamics which states that “in all energy exchanges‚ if no energy enters or leaves the system‚ the potential energy of the state will always be less than that of the initial state”

Most of the time‚ interning will open the doors to higher paying jobs in the future. On average‚ veterinarians make about $93‚438 a year. Even though it will take a long time‚ becoming a vet has always been my dream. This year‚ I was introduced to a job I quickly became interested in.

I am choosing to study how the PSI (pounds per square inch) of a football is affected by the temperature. I chose to study this because I like football and I always pondered this question. I believe that this is a worthwhile question to study because these studies can help improve the game as the weather gets colder. As air cools‚ it expands‚ so when a football gets colder‚ the air inside it expands. This expansion causes the air pressure to decrease. The air pressure decreases because the molecules
