In the investigation of a murder, a lifeless body was found by Gil Grissom exactly at 8:00 PM, being alert, he measured the body temperature by recording it at 30oC. Two hours later, he noted that the body temperature was 23 ° C. Knowing that the room temperature was 17 ° C, determine the time at which the murder occurred. Consider that normal body temperature is 37 ° C. Report the time in decimals. For example, 1 hour 30 minutes...

Murder Investigation: When a glass of wine with a certain temperature is placed into a room, its temperature will converge to the room’s temperature according to the formula: F(t)=Fs+(F0-Fs) -.3t. Where F(t) is the temperature of the object after being in the room for t hours, F0 is the initial temperature of the object, and Fs is the temperature of the room that the object is in. Use this formula to investigate the scenario below and answer the following questions....

3. Premature infants often have difficulty regulating their body temperature because of their low birth weight and low body fat. Researchers hypothesized that immersion bathing in warm water would improve temperature regulation relative to the common practice of sponge bathing. Eight infants where available to test the hypothesis; four were randomly assigned to each of the two conditions (immersion, sponge) during their stay in the neonatal intensive care unit (NICU). The dependent variable was body temperature 15 minutes after the...
