“BMI is thought to provide medical professionals with a sense of whether or not an individual is at risk for certain obesity-related chronic diseases, such asheart disease, high blood pressure, diabetes and other comorbidities,” she adds. The reason why boils down to fat. The BMI is a qu...
With this, we are hypothesizing that the classical universe is S≡S0, and that the states Si, i≠0 have no physical reality (another thing is the quantum universe, which is reversible, so all its states have the same entropy! Although at the moment it is nothing more than a set of ...
Being able to identify and better understand your face shape is an invaluable asset for the discerning gentleman. Some men may consider it superficial but you will be amazed in how your approach to wardrobe and personal grooming choices will drastically benefit. Know your features and learn how ...
The weight of an astronaut plus his spacesuit on the Moon is only 270 N. A. How much do they weigh on Earth, in Newtons, assuming the acceleration due to gravity on the moon is 1.67 m/s squared? B. An object weighs 10 N on Earth. What will be its weight on a p...
Chi-square automatic interaction detection.CHAID was developed by Gordon Kass and uses chi-squared tests to find the best split. It's typically used for categorical variables and can handle multiway splits. CHAID handles categorical data nicely and can produce trees that are easier to interpret....
The patients were divided into 2 groups according to the final diagnosis (MS group and non-MS group) and into 3 age groups (18-30, 30-50, >50 years old). The prevalence and statistical difference of paraclinical tests were estimated between the groups. Chi-squared test was...
What is the acceleration of gravity (in meters per second squared) on this planet? Round A ball is dropped from rest from a height. The distance it has fallen in the last second of its motion and the distance it has fallen in the first three seconds are equal. Find the time it took...
The American conversation about high-speed rail has an internal debate that greatly bothers me, about whether investments should be incremental or not. An interview with the author of a new book about the Northeast Corridor reminded me of this; this is n
- Gross Primary Productivity is typically expressed in units of energy, such as kilocalories (kcal), per unit area (e.g., meter squared) per unit time (e.g., year). Therefore, the unit can be written as: - kcal/m²/year 4. Conclusion: - In summary, Gross Primary Productivity is...
- The dimension of velocity v is given by distance/time, which can be expressed as: (v)=(L)(T)=(L)(T−1) 4. Calculate the dimensions of velocity squared: - Squaring the velocity gives: v2=((L)(T))2=(L2)(T−2) 5. Combine the dimensions to find the dimension of energy:...
