What is the formula for Expected value of an exponential random probability variable

Logisitic Differential Equation form

SUVAT Equations

Sin²x is also equal to

cos squared also equal to

The cumulative distribution function of an exponential random variable

When you're dealing with probabilities involving the sample mean (like Xˉ\bar{X}Xˉ), you must

you must use the standard deviation of the sample mean, which is:

sigma/root n

when calculating confidence intervals on calculator, 1-samp z interval, u input the standard deviation as the question says, along with the sample size

but when you are calculating a probability using NCD you use the sigma/root n standard deviation

If a string is inextensible

• If the string can’t stretch, then any displacement of one block must cause an equal displacement of the other.

• That means their velocities and accelerations are locked to be the same magnitude.
