This would be the set of rational numbers.
When dealing with money, we deal with parts of dollars, written as decimals. Decimals can be written as fractions, so these are rational numbers.
Answer:
Answer is d
Step-by-step explanation:
- A computer programmer has a 35 change of finding a bug in any given program.
- we have to find probability that she finds a bug within the first 3 programs she examines
- success = 0.35, failure = 0.65
- She get a bug in the first program itself
- p = 0.35
- She get a bug in 2nd program
- q = 0.65×0.35 =0.2275
- She get a bug in the 3rd program
- r = 0.65×0.65×0.35
- r = 0.147875
- Add all the three probabilities for answer
- P = p+q+r
- P = 0.35+0.2275+0.147875
- P = 0.725375
- P = 0.73
- The probability of the answer is 0.73
1 ≤ 3 - x
x + 1 ≤ 3 <em>added x to both sides</em>
x ≤ 2 <em>subtracted 1 from both sides</em>
Number line: ←----------------------·2 (fill in the dot at 2 since it is "equal to")
Interval Notation: (-∞, 2]
If 1/3x + 3 = x, then x-1/3 = 3
so
2/3 x = 3
x = 3 * 3/2 = 9/2
