1. A team of Aggie engineers are testing a solar car over long distances. The table below lists the timeand odometer readings of a test run. Fill out the blank parts of the table (time interval, distance traveledduring that time interval, and average speed) using finite difference equations discussed in lecture 3.Please show your work for one time interval, one distance, and one average speed. You do not have toshow your work for the remaining calculations. What is the overall average speed of the car (theaverage of the averages)?Clock time (hr:min:sec)Odometer reading (mi)Time interval (hr)Distance (mi)Average speed (mph)2:01:46217.60:59:120:00:00102.0 157.82:58:55 3:47:01 4:13:00 5:36:17264.1 315.2420.3341.7Note: Feel free to use Excel to check your work. Just remember that when entering times in Excel, it maybe easier to use a special format - you can select formats for a cell using the format drop-down menu(the General format is the default).The Clock times abov were done a format found under the Custom list. After entering the Clocktime values, try changing the format of the cells to General. You will see that Excel stores times (anddates) as numbers. (In fact, the number 1 is equal to the start of Excel's time/date clock - midnight,January 1, 1900.) The fact that dates and times are numbers means you can do math with them!

Suppose that fund-raisers at a university call recent graduates to request donations for campus outreach programs. They report the following information for last year's graduates. Size of donation Proportion of calls 0.40 $0 0.30 0.25 Three attempts were made to contact each graduate. A donation of $0 was recorded both for those who were contacted but declined to make a donation and for those who were not reached in three attempts. Consider the variable x = amount of donation for a person selected at random from the population of last year's graduates of this university. (a) Write a few sentences describing what donation amounts you would expect to see if the value of x was observed for each of 1,000 graduates. to donate $25, and roughly $10 $25 $50 (c) What is P(x ≥ 25)? You would expect roughly of the graduates to donate nothing, roughly frequencies would be close to, but not exactly, these values. The four frequencies would add to (d) What is P(x > 0)? 0.05 (b) What is the most…
The next four questions (29 to 32) refer to the following: To most Canadians, earthquakes are viewed as rare occurrences, but they are actually quite common. In just one month in 2001, Natural Resources Canada recorded 215 earthquakes that affected Canada from B.C. to Nunavut to Newfoundland. We would like to determine whether there is a linear relationship between the location of an earth- quake X (measured in degrees latitude north of the equator) and the magnitude of the earthquake Y (measured on the Richter scale). The explanatory and response variables are measured for a sample of 13 earthquakes. The equation of the least squares regression line is ŷ = -3.05+ 0.10x. The ANOVA table is showm below: ге Source of Variation df Sum of Squares Mean Square F Regression Error Total 1.40 25.10

The following chart shows the percentage of the U.S. discretionary budget allocated to education from 2003 to 2009 (t = 3 represents the start of 2003). A bar graph titled "Percentage of U.S. budget on education" has a horizontal t-axis labeled "Year since 2000" and a vertical axis labeled "Percentage". The bar graph has 7 bars. Each bar is associated with a label and an approximate value as listed below. 3: 6.8% 4: 7% 5: 7% 6: 6.9% 7: 6.5% 8: 6.3% 9: 6.2% The following table shows the percentage of the U.S. discretionary budget allocated to education in 2003, 2005, and 2009 (t = 3 represents the start of 2003). Year t 3 5 9 Percentage 6.8 7 6.2 Find a quadratic model for these three years.

Oliver and Tony work at a dentist office. They had a conversation one day about how much time it took to complete a routine cleaning for each patient. Tony wondered if the time since the last visit to the office was related to the length of a cleaning. Oliver went to the filing cabinet and came up with the following data: x = Months since last visit y = Length of cleaning (mins) 6 20 13 49 6 8 9 15 33 35 42 14 7 11 9 55 36 52 29 E SALETSTRANICZON RUSSAREN Co JINSIEMELLET
