Add Supply 2 to left of Supply 1. Add Supply 2 to right of Supply 1. Points earned on this question: 0 Question 2 (Worth 5 points) (01.04 MC) Graph shows values along the horizontal axis and vertical axis. Coordinates are plotted to indicate two upward-sloping diagonal lines and two downward-sloping diagonal lines. Line 1 is a downward sloping line with point S at 300, 300 and Point U at 200, 400.
The result of these changes is changes results in location A having a score of 195, location B a score of 225, and location C a score of 210. Location B, therefore, is the preferred location. b. The spreadsheet shown in Problem 21 can be modified by changing the two evaluations as follows: • The entry in cell C7 is changed from 1 to 3, and • The entry in cell E7 is changed from 3 to 2. Making these changes results in location A having a score of 215, location B a score of 210, and location C a score of 200.

The first class in a relative frequency table is 50–59 and the corresponding relative frequency is 0.2. What does the 0.2 value indicate? Answer: 0.2 is equal to 1/5 or 20%, 0.2 indicates 20% of the data values are in this particular interval. 3. When you add the values 3, 5, 8, 12, and 20 and then divide by the number of values, the result is 9.6.
In 2004, there were approximately 4 working age individuals (aged 20-64) for every 1 person aged 65 and over. By 2056 this ratio is predicted to fall to about 2.1 meaning our dependence on the workers will increase hugely and sadly this means taxation will have to go up. But the UK is not alone in its concerns over pension provision; others include China whose elderly population could double between 2000 and 2027. Most of the developed world is having to consider how best to support older individuals in the presence of an ageing population: Increasing life-expectancy which means that people are spending more and more years in retirement and lower birth rates. In 1900, on average a 65 year-old man in the UK could expect to live for another 10 years (11 years for a
