Due to a negative value of P(X = x), it is found that the following is not a probability distribution.

---------------------

A sequence (x, P(X = x)) is a probability distribution if:

  • The sum of all values of P(X = x) equals 1.
  • There is no negative values of P(X = x).

In this problem, P(X = 2) is negative, thus, it is not a probability distribution.

Gravity pulls the metal down at 10 N, but the metal pieces RISES! At least how much force is needed to make it move upward?
prisoha [69]

Answer: Greater than 10 N

Step-by-step explanation:

Given

Gravity force on metal is 10 N

But the metal piece is rising i.e. there must be an upward force greater than 10 N

Suppose the force is F

So, we can write

\Rightarrow F>10\ N

Any force greater than 10 N is sufficient for the metal to move upwards

The greater the amount of force faster will be the movement

Find dy /dx of x² - 2x + 5 - 6x
BaLLatris [955]

Answer:

Step-by-step explanation:

If y=x^2-2x+5-6x then

y=x^2-8x+5 by combining like terms. (I'm thinking you might have mistyped the problem because this representation is weird).

\frac{dy}{dx}=2x-8

How can you determine if you need to use a combination or permutation to count the number of outcomes? Which will usually have m
Nadya [2.5K]

Answer with Step-by-step explanation:

Permutation : It is an arrangement of r elements out of n elements.

Combination : it is a selection of r element out of n elements .

Suppose we have a set

S={1,2,3}

If two elements are taken at a time then

Using permutation formula

Total number of outcomes=3P_2

Total number of outcomes=\frac{3!}{(3-2)!}

Total number of outcomes=3!=3\times 2\times1=6

Using combination formula

\binom{n}{r}=\frac{n!}{r!(n-r)!}

Total number of outcomes=\binom{3}{2}=\frac{3!}{2!1!}

Total number of outcomes=\frac{3\times2!}{2!}

Hence, total number of outcomes=3

Total number of outcomes determined by permutation have more outcomes.

Because permutation is an arrangement of elements  therefore, it consider order of arrangement of element   but combination is a selection of elements it does no consider order of elements

Arrangements of two elements out of 3 elements

{1,2},{2,3},{2,1},{3,2},{1,3},{3,1}

By using combination if two elements taken at a time then combination

{1,2},{2,3},{1,3}
