Correct answer choice is :
<h2>A) Directly changed by the experimenter</h2><h2 /><h2>Explanation:</h2><h2 />
In mathematical modeling, analytical modeling and experimental sciences, the values of dependent variables depend on the values of independent variables. The dependent variables describe the output or outcome whose change is being examined. An independent variable seldom named an experimental or predictor variable, is a variable that is being formed in an experiment in order to inspect the impact on a dependent variable, sometimes described as an outcome variable.
The answer is 15 percent.
5290-4600=690
690/4600=0.15
Covert the 0.15 into percent which is 15 percent
Here is the solution to the given problem above.
Given that for an 8 pound bag of tomatoes costs $5.60, we would want to know how much will it be for 11 pounds. First, we should know how much does it cost per pound. So 5.60 divided by 8 is 0.7. So per pound of tomatoes costs $0.7. Now to know how much for 11 pounds, we multiply 0.7 by 11 and we get $7.70. The correct answer therefore would be option C. $7.70. Hope this answer helps.
Answer:
18.84 estimated, 6π exactly
Step-by-step explanation:
Hi!
<u>The formula for finding the circumference of a circle is 2πr:</u>
In that case, all we need to do <em>first </em>is to divide the diameter by 2, so we can substitute that into the equation.
6 ÷ 2 = 3
So we have 2π × 3 to solve.
2π × 3 = 6π
We can estimate the circumference by multiplying by 3.14.
6 × 3.14 = 18.84
(actually multiplying by π gives 18.849... which is pretty close!)
Thus, the circumference is 
.
Hope this helps!
Answer: 640
Step-by-step explanation:
The scale factor is 20/5=4, so the ratio of the areas is the square of this, or 16.
Thus, the area of ABCD is 40(16)=640.
