Answer:
Explanation:
The general formula to calculate the probability of each event is:
- Probability = number of positive (desired) outcomes / number of total outcomes
Number of apples = 4
Number of peaches = 5
Number of fruits = 9
Since the three times you return the radomly selected fruit, and then mix it, the three times the probability is not affected by the previous selection; so, these are independent events, and you can calculate the probability of the joint event as the product of the probabilities of each individual event.
Probability of getting an apple = number of apples / number of fruits = 4 / 9
Probability of getting a peach = number of peaches / number of fruits = 5 / 9
<u />
Probability of getting a peach = number of peaches / number of fruits = 5 /9
- <u>Joint probability:</u>
= (4/9) × (5/9) × (5/9) = (4 × 5 × 5) / (9 × 9 × 9) = 100 / 729
4 10/8 breaks down to 5 2/8 = 5 1/4
3 1/2 + 1 3/4
3 1/2 = 3 2/4
3 2/4 + 1 3/4 = 4 5/4
the correct answer is 5 1/4
so yes, your answer IS correct!
Answer:
D
Step-by-step explanation:
Answer: No, it is not a right triangle.
Explanation:
9^2 + 7^2 (?) 12^2
81 + 49 (?) 144
130 = 144
Since 12^2 = 144, and the square root of 130 is 11.4^2, it is not a right triangle.
Answer:
An integer is a whole number (not a fractional number) that can be positive, negative, or zero.
Since it's a decimal it can not be an integer.
