Avalanche researchers have collected data to model the air temperature profile justabove the snow surface over a period of several hours on a particular day:T(t)=1- (tª – 40t² + 144)80where t is time in hours on a practical domain [0,5] from midnight and T is thetemperature in degrees Celsius. Answer the following questions. What is the air temperature at midnight? Express as a decimal to the nearest tenth:A/When is the air temperature at freezing?A/During what time interval, in the practical domain, is the air temperature abovefreezing?A/During what time interval, in the practical domain, is the air temperature belowfreezing?A/What is the maximum temperature on the practical domain? Enter your answer as adecimal to the nearest tenth.A/On what time interval, in the practical domain, is the temperature increasing? For adecimal, express your answer to the nearest tenth.A/

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).

Ocean currents are important in studies of climate change, as well as ecology studies of dispersal of plankton. Drift bottles are used to study ocean currents in the Pacific near Hawaii, the Solomon Islands, New Guinea, and other islands. Let x represent the number of days to recovery of a drift bottle after release and y represent the distance from point of release to point of recovery in km/100. The following data are representative of one study using drift bottles to study ocean currents. Σx = 476, Σy = 87.1, Σx2 = 62,290, Σy2 = 2046.87, Σxy = 11121.3,and r ≈ 0.94367. x days 72 76 32 91 205y km/100 14.7 19.6 5.3 11.7 35.8 a) Use a 1% level of significance to test the claim ? > 0.(Use 2 decimal places.)t =critical t= b) Find the predicted distance (km/100) when a drift bottle has been floating for 60 days.

The following data represent the muzzle velocity (in feet per second) of rounds fired from a 155-mm gun. For each round, two measurements of the velocity were recorded using two different measuring devices, resulting in the following data. Complete parts (a) through (d) below. Observation 1 2 3 4 5 6 791.1 793.1 794.1 791.2 794.5 790.6 795.8 789.0 800.3 786.8 800.6 787.0 A B Click the icon to view the table of critical t-values. a) Why are these matched-pairs data? A. The same round was fired in every trial. B. The measurements (A and B) are taken by the same instrument. C. Two measurements (A and B) are taken on the same round. D. All the measurements came from rounds fired from the same gun.

A King in ancient times agreed to reward the inventor of chess with one grain of wheat on the first of the 64 squares of a chessboard. On the second square, the King would place two grains of wheat, on the third square, four grains of wheat, and on the fourth square eight grains of wheat. If the amount of wheat is doubled in this way on each of the remaining squares, how many grains of wheat should be placed on a square 16? Also, find the total number of grains of wheat on the board at this time and their total weight in pounds. (Assume that each grain of wheat weighs 1/7000 pounds.)
