Calculate speed, distance or time using the formula d = st, distance equals speed times time. The Speed Distance Time Calculator can solve for the unknown sdt value given two known values. ... To solve for time use the formula for time,t = d/swhich means time equals distance divided by...
The calculator consists of an input module, a calculation module and a display module, wherein a calculation formula operated in the calculation module corresponds to a sampling method input in the input module; the calculation module consists of a read only memory (ROM) (5), a random access...
The sample size was determined at a 90% confidence interval and 5% margin of error and an expected prevalence of 50% using the formula as given by Thrusfield (2005) and validated using a sample size calculator (Raosoft Inc USA see www.raosoft.com). In the preceding year, the total ...
resulting in a 50% response rate. However, after data cleaning, only 97 responses were included in the final analysis. Demographic characteristics of our population stratified by category can be found in Table1. Our sample was evenly divided between males and females (50.5% and 49.5%, respective...
The sample size for the study was calculated by using StatsDirect statistical software version 2.7.8 at 95% confidence interval based on 13.2% as the highest prevalence of bTB in indigenous cattle in Tanzania [12] with 2% as an acceptable absolute deviation of sample rate from population rate....
