Hello there!

We reverse the whole problem. 12 - 4 = 8.

x = 8.

8 + 4 = 12.

x = 8

I think the answer is 8+4=12, I'm not sure what the question was, it was "what's x?" right?

edit: Nevermind, the other person has a better answer than me and they explain it so just ignore this...

Answer:

Is there ever a time when the X is the same? if so, then it is not a function, if the X is never the same, it is a function.

Step-by-step explanation:

I'm sorry, but I'm to lazy to do the math right now, but maybe this will help?

A colored chip is yellow on one side and red on the other. The chip was flipped 50 times and landed red side facing up 21 times.
meriva

<u>Answer:</u>

42%

<u>Step-by-step explanation:</u>

We know that the number of times red side is faced up = 21; and

the total number of times colored chip is thrown = 50

Frequency of red side = (No of times red side is faced up / Total number of times colored chip is thrown)   * 100%

Frequency of red side = (21 / 50) * 100% = 0.42 * 100 = 42%

Therefore, the relative frequency of the chip landing with the red side facing up is 42%.

Suppose P(E) = 81%; P(E and F) = 9%; and P(E or F) = 65%,
PIT_PIT [208]

Using Venn probabilities, it is found that P(F) = -0.07, which is not a probability, as it is a negative value.

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

  • We have two events, E and F.
  • Their probabilities are: P(E) = 0.81, P(E \cap F) = 0.09, P(E \cup F) = 0.65
  • The probabilities are related by the following equation:

P(E \cap F) = P(E) + P(F) - P(E \cup F)

  • Replacing into the equation, we can find P(F).

0.09 = 0.81 + P(F) - 0.65

0.16 + P(F) = 0.09

P(F) = -0.07

P(F) = -0.07, which is not a probability, as it is a negative value.
