First, find the probability of picking one 9. There are four nines in a deck of 52, so the probability is 4/52, which is 1/13.
The probability of picking a 9 the second time is 1/17, because if a 9 was picked the first time, then there are three 9s left and 51 cards left in total.
To find the probability of both events happening, multiply the individual probabilities together:
(1/13)(1/17)
The probability that both cards picked will be 9s is 1/221.
1. All whole numbers (0, 1, 2,...) and their negative equivalent ( -1, -2, -3, ...) are considered integers. Hence, from the choices provided, the answer would be A.
2. Real numbers consist of rational and irrational numbers. So the statement "Every real number is a rational number" is not correct. Thus, the answer is D.
3. 5.85, 63.4, and 27.5 are terminating decimals. This means that they have a fixed decimal conversion and does continue endlessly. Meanwhile, for 8.52624 . . ., its digit goes on forever. So, odd one out would be C.
4. Irrational numbers are those that cannot be expressed as the ratio of two numbers. Examples for this would be the value of the constant e, √2, etc. Rational numbers, on the other hand, are numbers that can be expressed as ratio of two numbers. As can be seen irrational and rational numbers are opposite of ech other, by definition. Hence, irrational numbers cannot be classified as rational numbers. That will give an answer of E.
5. From the previous items, we can see that both rational and irrational numbers are part of the real number system. This means that every irrational number is a real number. Hence, the answer is C.

Answer:
x ≤ 9
Step-by-step explanation:
x - 6 ≤ 3
+ 6 + 6
X ≤ 9
Move the decimal place so its in between the first 2 non zero numbers, then count the amount of spaces you moved the decimal
6400000
6.400000
I moved it 6 spaces so it would be 10^6
6.4x10^6
