- Solve the problem. An average human heart beats 60 times per minute. If the average person lives to the age of 86, how many times does the average heart beat in a lifetime?3. Increased research and discussion have focused on the number of illnesses involving the organism Escherichia coli which causes a breakdown of red blood cells and intestinal hemorrhages in its victims. Sporadic outbreaks of E. coli have occurred in Colorado at a rate of 2.5 per 100,000 for a period of 2 years. Let us suppose that this rate has not changed. a. Can x, the number of cases of E. coli in a year, be treated as a binomial random variable? Why or why not? b. Can x, the number of cases of E. coli in a year, be treated as a Poisson random variable? Why or why not? c. Can the probability of x, the number of cases of E. coli in a year, be calculated using the Poisson approximation to the binomial? Why or why not? d. Calculate P(x-5) using all of the above methods, if applicable.A typical person has an average heart rate of 69.0 beats/min. Calculate the given questions. How many beats does she have in 7.0 years? How many beats in 7.00 years? And finally, how many beats in 7.000 years? Pay close attention to significant figures in this question. 7.0 years: 2.5 x10% beats 7.00 years: 2.65 x108 beats Incorrect 7.000 years: 2.650 ×10 beats Incorrect

Assume the average heart rate is 69 beats/min and a life span of 75 yr. a) 3 x 108 beats O b) 3 × 1010 beats c) 3 × 10° beats d) 3 x 107 beatsA. On the average, what volume of blood, in liters, does the heart pump during each beat? B. On the average, what volume of blood, in cubic centimeters, does the heart pump during each beat?
- A typical person has an average heart rate of 71.0 beats/min. Calculate the given questions. How many beats does she have in 6.0 years? How many beats in 6.00 years?

Pay close attention to significant figures in this question. 6.0 years: beats 6.00 years: beats beats 6.000 years:A study finds that the metabolic rate of mammals is proportional to m3/4, where m is the total body mass. By what factor does the metabolic rate of a 70.0-kg human exceed that of a 6.41-kg cat?The World Health Organization differentiates bone diseases using bone density measurements. The table given below is the criteria for diagnosing different bone diseases (assuming that the mean normal bone density is 1.8 g/cm and that 1SD is approximately 10% of the mean bone density).

- 8. A man is driving at a speed of 90km/h for 2 hours and slowed down to 82km/h for 1.5 hours. What is the total distance in km?4. A man is standing near a window. The window is 6.06 meters tall. The man watches a falling stone pass by the window in 0.43 secs. From how high (in meters), measured from the bottom of the window, was the stone released? Round off to two decimal places.According to Timothy Treadwell in 2001 "Now, the bears I live with average, the males are on average twelve hundred pounds. They're the largest bears in the world and they've been clocked at 41 [mph] and they've run a hundred meter dash in 5.85 seconds which human on stimulants doesn't even approach. a. Compute the speed of a grizzly bear using Mr. Treadwell's hundred-meter statement. b. Compute the momentum of a grizzly bear using the speed you calculated in part a. and the average mass stated by Mr. Treadwell. c. How fast would a 250 lb man have to run to have the same momentum you calculated in part b? d. How fast would a 4000 lb car have to drive to have the same momentum you calculated in part b?
