Identify which statement about the mean of a discrete random variable is not true or state that they are all true.Choose the cor

pashok25 [27]

Answer:

A, C are true . B is not true.

Step-by-step explanation:

Mean of a discrete random variable can be interpreted as the average outcome if the experiment is repeated many times. Expected value or average of the distribution is analogous to mean of the distribution.

The mean can be found using summation from nothing to nothing x times Upper P (x) , i.e ∑x•P(x).

Example : If two outcomes 100 & 50 occur with probabilities 0.5 each. Expected value (Average) (Mean) : ∑x•P(x) = (0.5)(100) + (0.5)(50) = 50 + 25 = 75

The mean may not be a possible value of the random variable.

Example : Mean of possible no.s on a die = ( 1 + 2 + 3 + 4 + 5 + 6 ) / 6 = 21/6 = 3.5, which is not a possible value of the random variable 'no. on a die'

Which card has the solution x = 23?

morpeh [17]

I need a photo but ill give you some information this will be with exponents.

Write down the problem. Here it is:

2^2(x+3) + 9 - 5 = 32

Resolve the exponent. Remember the order of operations: PEMDAS, which stands for Parentheses, Exponents, Multiplication/Division, and Addition/Subtraction. You can't resolve the parentheses first because x is in the parentheses, so you should start with the exponent, 2^2.2^2 = 4

4(x+3) + 9 - 5 = 32

Do the multiplication. Just distribute the 4 into (x +3). Here's how:

4x + 12 + 9 - 5 = 32

Do the addition and subtraction. Just add or subtract the remaining numbers. Here's how:

4x+21-5 = 32

4x+16 = 32

4x + 16 - 16 = 32 - 16

4x = 16

Isolate the variable. To do this, just divide both sides of the equation by 4 to find x. 4x/4 = x and 16/4 = 4, so x = 4.

4x/4 = 16/4

x = 4

Check your work. Just plug x = 4 back into the original equation to make sure that it checks out. Here's how:

2^2(x+3)+ 9 - 5 = 32

2^2(4+3)+ 9 - 5 = 32

2^2(7) + 9 - 5 = 32

4(7) + 9 - 5 = 32

28 + 9 - 5 = 32

37 - 5 = 32

32 = 32
