Answer:

x = -16 / 11

Explanation:

Twelve Less Than A number: x - 12

Is The Same As: =

Twelve Times The Number: 12x

Increased By Four: + 4

x - 12 = 12x + 4

Subtract 12x from both sides

x − 12 − 12x = 12x + 4 − 12x

−11x − 12 = 4

Add 12 to both sides

−11x − 12 + 12 = 4 + 12

−11x = 16

Divide both sides by -11

−11x / -11 = 16 / -11

x = -16 / 11

Select the statement that does not correctly use probability to describe an event

Nina [5.8K]

Answer:

Step-by-step explanation:

Probability is, by definition, a number between 0 and 1, which can be expressed as a fraction or a percentage. For example, the odds of getting heads if you throw a fair coin are 50%, or ½. The odds of not getting heads are 1-½=½.

If the probability of something happening is 1, it means that that thing will happen for sure. Likewise, if the probability of an event is 0, it means that the event will never happen.

You can therefore easily understand that it doesn't make sense to have a probability greater than 1, as we have in choice D.

You can notice that each term of the sequence has a denominator with powers of 2. The first term has 2 powered to 0, the second term has a 2 powered to 1 and so on. The numerator is always 3.

Then, for the n-th term, you have:
