Which of the following statements are correct? A. The statement that the random variable X is normally distributed with parameters is often abbreviated . B. If the random variable X is normally distributed with parameters , then . C. The graph of any normal probability density function is symmetric about the mean and bell-shaped, so the center of the bell (point of symmetry) is both the mean of the distribution and the median. D. If the random variable X is normally distributed with parameters , then a large implies that a value of X far from may well be observed, whereas such a value is quite unlikely when is small. E. All of the above statements are correct

A. The statement that the random variable X is normally distributed with parameters is often abbreviated.

Step-by-step explanation:

The X is normally distributed with parameters u and  is often distributed as X ≈N (u 2 ). The correct answer is a. The statement that the random variable is normally distributed.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

you are playing an adventure game on your computer. you come across a troll who won't let you pass and there is no other way to get to the other side of the river except over the bridge he is guarding.

the troll is a nerd. he takes great delight in watching people struggle with his problems. very few get them. he only gives you one chance and then he changes the puzzle. you have to solve this one.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?
