Suppose that a body was discovered at midnight and its temperature was 80 degrees Fahrenheit. The temperature of the room is kept constant at 60 degrees Fahrenheit. Two hours later the temperature of the body dropped to 75 degrees Fahrenheit. Find the time of death. Use the military time format (HHMM), e.g., 0705 for 7:00 AM, 1345 for 1:45 PM, 1623 for 2:23 PM. Do not mind the comma that might be put automatically.

In the year​ 2000, a country with a population of 90 million had 12,960 traffic fatalities. Find the 2000 fatality rate in deaths per​ 100,000 people. Round to two decimal places.

The valence of a song is measured from 0 to 10 and detects the musical positiveness conveyed in the song. Tracks with high valence sound more positive (e.g. happy, ch with low valence sound more negative (e.g. sad, depressed, angry). The valence was computed for 42,000 songs on Spotify in the genres of Techno, Techhouse, Trance, Trap, Psytrance, DnB, Hardstyle, Underground Rap, Trap Metal, Emo The table below shows the number of songs with a given valence measurement. Valence 1.5 2.5 4.4 5.3 6.3 6.7 7.7 8.7 9.7 Number of songs 3557 3175 2388 2078 1579 1438 1023 651 245 Source: Kaggle (a) Based on a scatter plot of the data in the table, why is a linear model appropriate? The scatter plot suggests a steady,---Select--- with a ---Select--- slope. (b) Find the linear model that gives the number of songs with a given valence, where v is the valence, for 0 ≤ v ≤ 10. (Round all values to two decimal places. L(v) = ---Select--- C (c) The constant rate of change for the model is (d) Use the…

Safety regulations require that the time between airplane takeoffs (on the same runway) will be at least 2 minutes. When taking off, the run time of an airplane on the runway is 48 seconds. Planes are on average waiting 5 minutes and 30 seconds for takeoff. On average there are 16 planes taking off per hour. How many planes are either on the runway or waiting to take off? Note: Round your answer to 2 decimal places.
