Answer:
Step-by-step explanation:
Triangle ABC: 30^2 + 40^2 = 50^2 is a true statement, so by the Pythagorean theorem, this is a right triangle.
Triangle XYZ: 1^2 + 1^2 = 2^2 is a false statement, so by the Pythagorean theorem, this is not a right triangle.
Triangle EFG: 8^2 + 15^2 = 17^2 is a true statement, so by the Pythagorean theorem, this is a right triangle.
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.

<h2>
Answer:</h2>
The number is -2.
<h2>
Step-by-step explanation:</h2><h3>Written out, our equation looks like this:</h3><h3>(-5·x)+2=12</h3>
We'll start of by taking our final result of 12 and subtracting 2, as the beginning of the statement says "two more."
<h3>12 minus 2 gives us
10.</h3>
Now, since the statement says "the product of -5," we will take this 10 and divide by -5.
<h3>10 divided by -5 gives us -2.</h3>
This means that our number, x equals -2. Of course, we must input this solution to double check our work.
<h3>(-5·<u>
-2</u>)+2=12</h3><h3>10+2=12</h3><h3>12=12</h3>
<h2>Our final answer is x=-2!</h2>
<span>10=z/2+7
Subtracat 7 from both sides
3=z/2
Multiply 2 on both sides
Final Answer: 6 = z</span>
