Answer:

Step-by-step explanation:

Independent Variable (IV):  Special college preparation program

How will you describe the IV: Independent variable or known as manipulated variable is a variable where the researcher purposely manipulate the variable to see how it affect the results of the experiment.

Dependent variables (DV): Math placement scores of college applicants

How will you measure the DV: DV can be measured by recording the math placement scores of each applicants who have or have not taken the special college preparation program.

Explanation: In this case, the researcher wants to see how taking special college preparation program (IV) can affect the math placement scores of the applicants (DV). Explanation: In this case, the researcher wants to see how taking special college preparation program (IV) can affect the math placement scores of the applicants (DV).

Hypothesis:

If the applicants take the special college preparation program, the applicants will have higher math placement scores compared to the one who have do not take the program.

Use Greens Theorem to evaluate integral x^2ydx - xy^2dy, where C is 0 ≤ y ≤ √9-x^2 with counterclockwise orientation
Ratling [72]

Answer:

Step-by-step explanation:

a circle will satisfy the conditions of Green's Theorem since it is closed and simple.

Let's identify P and Q from the integral

P=x^2 y, and Q= xy^2

Now, using Green's theorem on the line integral gives,

\oint\limits_C {x^2ydx-xy^2dy } =\iint\limits_D {y^2-x^2} \, dA\\\\

(x - 6)^2 - 12 = x^2- 12x + c. What is the value of c?
mojhsa [17]

Answer:

C = 24

Step-by-step explanation:

(x - 6)² - 12 = x² - 12x + c

(x - 6) (x - 6) -12 = x² - 12x + c

x(x - 6) - 6(x - 6) - 12 = x² - 12x + c

x² - 6x -6x + 36 - 12 = x² - 12x + c

x² - 12x +36 - 12 = x² - 12x + c

x² - 12x + 24 =   x² - 12x + c

             24 = c

Solve for the unknown variable: -8m - 9 = 39
Lemur [1.5K]

Answer:

m =-6

Step-by-step explanation:

To solve for the unknown variable, m, we have to get m by itself. Perform the opposite of what is being done to the equation.

-8m-9=39

9 is being subtracted from-8m, so add 9 to both sides. Addition is the opposite of subtraction.

-8m-9+9=39+9

-8m=39+9

-8m=48

-8 and m are being multiplied. Divide both sides by -8, because division is the opposite of multiplication

-8m/-8=48/-8

m=48/-8

m= -6
