Answer:
x= 4, y=3
Step-by-step explanation:
2x + 3y = 17
3x - 2y = 6
----------
<u>If we double the first and triple the second equation, and add up, we can get rid of y:</u>
- 4x+6y= 34
- +
- 9x - 6y= 18
- -----------------
- 13x= 52
- x= 4
<u>Then it is easy to find the value of y:</u>
<u>Answer is</u>: x= 4, y=3
The answer is 6.2857 you take all the values add them together then divide by the amount of values
25 is the greatest common factor of 75 and 25. 3 x 25 = 75.
Step-by-step explanation:
Replacement means the probability of each trial is the same (the trials are independent).
For example, let's say you have a standard deck of 52 cards, and you want to find the probability of drawing a queen card twice.
There are 4 queens, so the probability on the first draw is 4/52.
You then replace the queen, so there are still 4 queens in the deck. So the probability on the second draw is still 4/52.
The total probability is the product: 4/52 × 4/52 = 1/169
If you didn't replace the queen after the first draw, there would have been 3 queens in the deck, and the probability on the second draw would have been 3/52.
