For an urban planning study, in year zero ofthe project there was an initial quantity of 200,000 vehicles. After five years ofobservations, the number of vehicles had grown to 250,000 units. Determine:a) the proportionality constantb) the time in which the vehicle fleet reaches 350,000 units

Animals and people that take in more energy than they expend will get fatter. Here are data on 12 rhesus monkeys: 6 lean monkeys (4% to 9% body fat) and 6 obese monkeys (13% to 14% body fat). The data report the energy expended in 24 hours (kilojoules per minute) and the lean body mass (kilograms, leaving out fat) for each monkey. Lean Obese Body Mass Energy Body Mass Energy 6 1.13 8.2 0.91 8 1 9 1.32 9.2 1.46 10.4 1.18 10.5 1.62 12.7 1.46 9.2 1.02 12.2 1.28 9 1.16 10.6 1.37 (a) What is the mean lean body mass of the lean monkeys? ANSWER x¯=x¯= kilograms. (b) What is the mean lean body mass of the obese monkeys? ANSWER x¯=x¯= kilograms.
The Dorben Co. uses a standard hour plan with a base wage of $9/h. It hires an IE consultant to plan a batch production run of 300 units. This consultant has a worker on the line produce 2 units. The first takes 10 min and the second 9.7 min. Assuming that the worker continues to improve her performance, what will she be paid for the full batch of 300 units under the standard hour plan? What is the unit cost for the first unit made? What is the cost for 300th unit? there is already an answer for this question in chegg but it does not explain clearly in steps. I need some clear explanation thnks
Hectic Repair Org. HRO) helps repair homes that are structurally weakened by minor earthquakes. After an earthquake, SmartProtect, an insurance company of some affected customers in the area estimates that the standard time to perform a preliminary damage assessment on an average-sized house would be about two hours. On behalf of the affected customers, SmartProtect is willing to pay a HRO employee doing such damage assessments $65 per hour. Suppose that Michael (an employee at HCRO who does flood damage assessment) takes three hours to complete the assessment on an average-sized house. What is Michael efficiency based on the standard time estimated by SmartProtect? a. Approximately one hundred and fifty percent. b. About one-third of an assessment job per hour c. Approximately one hundred and thirty dollars per assessment d. Approximately one hundred and ninety five dollars per assessment (before taxes) e. Approximately sixty seven percent.
Of the 2000 passengers, crew, and staff that boarded a cruise ship, 8 have the flu. After one day of sailing, the number of infected people has risen to 12. Assuming that the rate at which the flu virus spreads is proportional to the product of the number of infected individuals and number not yet infected, determine how many people will have the flu at the end of the 10-day cruise.

The dams in and around Cape Town form part of the Western Cape Water Supply System, which is an integrated and collectively managed system of dams, pump stations, pipelines, and tunnels. In addition to servicing Cape Town, the system supplies water to towns in the Overberg, Boland, West Coast, and Swartland areas, and provides irrigation water for agriculture. The change in depth of the Steenbras dam from one day to the next, measured (in feet) at in Cape Town, is a random variable Y with the following density function: f(y) = 2 < y< 4, elsewhere. 2.4.1. Define the random variable Y. 2.4.2 State what type of distribution does Y follow and why: 2.4.3. Find E (Y) and interpret your answer.
A company makes three components for sale. The components are processed on two machines: a shaper and a grinder. The time required. (in minutes) on each machine are as follows: Component Shaper Time Grinder Time A 6 4 B 4 5 C 4 2 The shaper is available for 7200 min. and grinder for 6600 min. No more than 200 units of component C can be sold, but up to 1000 units of each of the other components can be sold. In fact the company has orders for 600 units of component A that must be satisfied. The profit contributions for components A, B and C are $8, $6 and $9 respectively.

A city of 70000 residents has an average water demand of 250 L/ca.day. The institutional and commercial, and industrial average areas in the city are 250 and 350 Ha, and water demand expected is 20 and 23 m3 /Ha.d. The public water use and water unaccounted for are 10 and 6 % of total municipal water demand, respectively. Calculate total municipal demand and each component quantity as a % of total municipal demand.
You are proxided with the following information about your city: Total population 2020 = 85,000 Median household income 2020 = € 36,000 Average household income 2020 = € 42,000 Sales of clothes and shoes per square meter in 2020 = € 2,340 Make whatever assumptions areneeded and estimate the total required square meters of clothing and shoe stores in your city in 2021. Show clearly and explain all the formulas and assumptions that you use for your calculations.
