The genotype of an organism is the inherited map it carries within its genetic code. Not all organisms with the same genotype look or act the same way because appearance and behavior are modified by environmental and developmental conditions.
To take the average, you need to use both of the given z values(-8 and 3) and figure out the slope of the line at each point. slope at each point: -16(-8)= 128 and -16(3)= -48. The average of 128 and -48, calculated as (128-48)/2, is 40. The average rate of change of the function is 40. collegekid1988 Â· 8 years ago.
Thus, for a house with 15 ACH at 50 Pascals (ACH50 = 15), one would predict an average air change rate of (15/20 =) 0.75 ACH. This simple formula yields surprisingly reasonable average infiltration estimates, even though it ignores many details of the infiltration process.any researchers have sought to develop a correlation between a one-time pressurization test and an annual infiltration rate. average infiltration rate (ACH) = ACH50(1) ----- 20. A person conducting pressurization tests on a particular house can collect considerable information about these details.
