a large study used records from canada's national health care system to compare the effectiveness of two ways to treat prostate disease. The two treatments are traditional surgery and a new method that does not require surgery. The records described many patients whose doctors had chosen each method. The study found that patients treated by the new method were significantly more likely to die within 8 years. You have 300 prostate patients who are willing to serve as subjects in an experiment to compare the two methods. Describe a completely randomized design for this experiment. Write a few sentences describing how you would implement your design.

are 2x +4 = 10 and 3x +6 = 15 equivalent. equations? how do you know.
Answers
Answer:
Yes, the two equations are equivalent.
Step-by-step explanation:
For the first equation, we will solve for x.
2x + 4 = 10
Subtract 4 from both sides...
2x + 4 = 10
-4 -4
It then becomes
2x = 6
Then we divide by 2 on both sides.
2x = 6
2 2
Then the answer is...
x = 3
Now let's also solve for x on the second equation.
3x + 6 = 15
Subtract 6 on both sides to get x alone...
3x + 6 = 15
-6 -6
Then it is..
3x = 9
Lastly, divide by 3 on both sides...
3x = 9
3 3
Then it becomes
x = 3.
Then we see that both equations have x = 3, meaning when both x's = 3, then both equations will be equivalent. I hope this helps, and I hope it is not wrong, but I don't think it is.

Answer: Not lying cause what's the point of lying to someone asking for help. The answer is x = -7
Step-by-step explanation: X= -7 because if you look at a graph with negative and positive on it along with the Y and the X on it. Then you'll see that the middle of the plus is zero the left of the middle (going down the X axis) is negative. And the right side of the X axis is positive and the line is on the negative side of the X axis. That's why instead of it being Y= -7 ( which is NOT the answer) is wrong because the line is over the X axis instead of the Y axis.

DeShaun and Vu are brothers who like to make bets about the outcomes of different contests between them. Before the last bet, the ratio of the amount of Deshaun's money to the amount of Vu's money was 4:7. Vu lost the latest competition, and now the ratio of the amount of Vu's money is 8:3. If Vu had $280 before the last competition, how much does Vu have now that he lost the bet?
Answers
Answer: Vu have $60.
Step-by-step explanation:
Given: Before bet, the ratio of the amount of Deshaun's money to the amount of Vu's money was 4:7.
Let Deshaun's money =4x and Vu's money = 7x
If Vu had $280 before the last competition, then
7x = 280
⇒ x = 40 [Divide both sides by 7]
Deshaun's money = 4x = 4 x 40 = $160
After Vu lost bet, ratio becomes 8:3.
Let Deshaun's money = 8y and Vu's money = 3y
For Deshaun, 8x = 160 ⇒ y = 20 [divide both sides by 8]
Vu's money = 3 (20)=$60
Hence, Vu have $60.

x/16- (x+2)/8=2 pls help, need answer soon.
Answers
Answer:
x = -36
Step-by-step explanation:
Step 1: Write equation
x/16 - (x + 2)/8 = 2
Step 2: Solve for x
Multiply both sides by 16: x - 2(x + 2) = 32Distribute -2: x - 2x - 4 = 32Combine like terms: -x - 4 = 32Add 4 to both sides: -x = 36Divide both sides by -1: x = -36Step 3: Check
Plug in x to verify it's a solution.
-36/16 - (-36 + 2)/8 = 2
-9/4 - -34/8 = 2
-9/4 + 17/4 = 2
8/4 = 2

C.) False, counterexample of 15
1) 15 is divisible by 3 but not by 6
we know that 15 = 3*5 or 15/3=5, So 15 IS DIVISIBLE BY 3
BUT 15/6=2.5 THIS PROVES 15 IS NOT PERFECTLY DIVISIBLE BY 6
2) 12= 3*4 & 6*2

what is the value of 4(x-2)(x-3)+7(x-2)(x-5)-6(x-3)(x-5) when x=5
Answers
Answer:
The value is 24
Step-by-step explanation:
We want to find the value of the given expression when x = 5
Simply substitute 5 into the given expression.
Thus, we have;
4(5-2)(5-3) + 7(5-2)(5-5) - 6(5-3)(5-5)
Any part of the expression with 5-5 will be zero and will cancel out
Thus, we have
4(3)(2) = 4 * 3 * 2 = 24
The required value of equation at x = 5 is 24.
Given ;
Equation is = 4(x-2)(x-3) + 7(x-2)(x-5) - 6(x-3)
We have to calculate the value of expression when x = 5
To solve the equation substitute x = 5 in the given equation
= 4(x-2)(x-3) + 7(x-2)(x-5) - 6(x-3)(x-5)
= 4(5-2)(5-3) + 7(5-2)(5-5) - 6(5-3)(5-5)
Simplify the equation
= 4(3)(2) + 7(3)(0) - 6(2)(0)
= 4.(6) + 7(0) - 6(0)
= 24 + 0 - 0
= 24
The required value of the equation at x = 5 is 24.
