Answer 1

The atmosphric pressure (in Millibar) at a given altitudes (in meters) is shown in table Altidtide : 0 1000 2000 3000 4000 5000 6000 000 Pressure : 1011 884 773 676 591 517 452 395 Artitude: 8000 8000 10000 Pressure: 346 302 204 (a) using graphing calculator to make a scatter diagram of the above data for atmospheric pressure p at altitude se The correct scatter plot from the ginen options A,B,C,D. üs A. since data and scatter blot shows the decreasing function at 3=0, P=1011 and s=10,000, P=204 these two points are located in scatter blot diagram A. So correct choice [A] (b) A function which fit the data best is Exponential function) (c) The function Peas = 1011e abbroximate the data Now, we use a graphing calculator to graph P and the data on the same coordinate aves. The correct graph from the given options A,B.CD is IC di bep to predict the pressure at isoom and 11,000 m. and compare them to the actual values of 846 millibarn and 227 millibars, respectively. plisoo) = 1011e-0.0001342(1500) = 826.66 827 P(11,000) = 10ll e-0.000 1343 (11000) = 231.85 • 232 P (1,500)=1821) mb The model underestimates the Value at 1500m. P ( 11,000) = (232 mb The model overestimates the value at 11,000 m. es The function Peas = 1010 0.0001342*
