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.

Sharon tracks the number of cupcakes she sells each day for a week. the numbers of cupcakes she sold are 23, 25, 32, 35, 36, 25,
Nezavi [6.7K]
To find the mean: You have to add them all together, then divide them by how many numbers there are.
 
So: 23+25+32+35+36+25+27 = 203

How many numbers did we add up? 7.

203 ÷ 7 = 32.85714 (That is the mean rounded up to the nearest hundredth thousandth).

What is the range for f(x) = 2^x
Natali [406]

Given the function:

f(x)=2^x

The function can also be written as:

y=2^x

The range of the function will be all set of y values.

To find the range, let's graph the function below.

We have:

From the graph above, all possibe y values range from 0 to infinity.

Therefore, the range of the function is from zero infinity.

In interval notation:

Range = (0, +∞)

ANSWER:

4. (0, +∞)

Use the Angle Addition Postulate to find the measure of each angle.
Simora [160]
For number 15 and 16, you just have to find the absolute difference between the two points along the calibration of the protractor.

15. ∠BXC = |B - C| = |140° - 110°| = 30°
16. ∠BXE = |B - E| = |140° - 30°| = 110°

For numbers 20 and 21, apply the Angle Addition Postulate. This is when you add the individual interior angles to equate to the total angle.

20. ∠PQS = ∠PQR + ∠RQS
      112° = 72°+ 10x°
       x = 4

21. ∠KLM = ∠KLN + ∠NLM
      135° = 47°+ 16y°
       y = 5.5
