The Q critical value is calculated using a formula that takes into account the sample size, the confidence level, and the degrees of freedom. The formula is Q_crit = (n-1)/ (4n), where n is the sample size. This value can also be found in statistical tables or calculated using statistical software. 3.
The MRC button on a calculator stands for "Memory Recall Clear". This button allows you to recall a previously saved number from the calculator's memory and clear the memory simultaneously. To use it, simply press the MRC button followed by the number you want to recall. The calculator will display the number and remove it from the memory. 2.
Statistics. In summary, the definitions of mild and extreme outliers in statistics refer to values that are 1.5 to 3 times the interquartile range away from the nearest quartile. These numbers are not chosen arbitrarily, but are based on the concept of quantiles, which are used as a diagnostic tool to understand the nature of the data.
Vortico. If the video has a timestamp with milliseconds or hundredths of seconds or a constant framerate, you can calculate the speed with enough accuracy. Estimate the distance of a specific point on the car between two frames and divide it by the time between the frames you are comparing.
The process for saving equations on a ti-36x pro is as follows: Enter the equation into the calculator. Press the "STO" (Store) button. Choose a variable to store the equation in. Press the "ENTER" button to save the equation.
How is power dissipation calculated in resistors? The power dissipation in a resistor can be calculated using the formula P=I^2*R, where P is the power dissipation in watts, I is the current passing through the resistor in amperes, and R is the resistance of the resistor in ohms. 3.
The equilibrium number of vacancies can be calculated using the following equation: Nv = Nexp (-Qv/RT), where N is the total number of lattice sites, Qv is the activation energy for vacancy formation, R is the gas constant, and T is the temperature in Kelvin. 3.
The ratio should be r1/r2 = 2^x, r2/r3 = 2^x, etc. The problem is that r1/r2 gave x=3.8, when the other two gave 1.6 and 1.2, and we are supposed to find the average to get the reaction order. The average rounds off to 2, but that is because of the major outlier of 3.8. I checked and to find R you use 6.3x10^-4 / time of reaction to get the R's.
Homework Statement A laboratory lead consists of 16 strands of fine copper wire twisted together. Each strand is 30 cm long with a diameter of 0.15 mm. Calculate the potential difference across the lead when it is carrying a current of 2.0 A. (The resistivity of copper = 1.7 × 10^-8...
Calculation Cam Design Shaft Torque. In summary, the camshaft torque is calculated by taking the normal force of the cam follower on the cam, and then multiplying that by the distance from the cam shaft center to the point of contact. The torque required increases as the valve lift increases. Apr 5, 2016. #1.
