A data set contains information on the grams of fat and number of calories in 28 different fast foods. The correlation coefficie
k0ka [10]

Using a calculator, it is found that for the two-tailed test of significance, the p-value is of 0.9195.

The correlation coefficient is also called <u>Pearson's r-score</u>, and is used for two-tailed tests. To find the p-value, the information needed is:

  • The value of the Pearson's r-score, that is, the value of the correlation coefficients.
  • The sample size.

In this problem, we have that the correlation coefficient is of r = 0.02, with a sample size of n = 28.

  • Using it as the input for a r-score calculator, the p-value is of 0.9195.

F(x)=9÷4x-15 for x=4
enyata [817]

9/4x  -15     for x=4

To find this answer you must plug the 4 everywhere the x is located.

(9/4)(4)  -15

Multiply 9/4 by 4

(9/4) x 4 = 9

Now we take our 9 answer and add it to -15.

9-15 = -6

The answer is -6

-

-

For the other equation, you also must plug in 3 where ever x is located in the equation.

5/3x -3/5

(5/3)(3) -3/5

Multiply 5/3 and 3

(5/3) x 3 = 5

Take that answer of 5 and add -3/5

5- (3/5) =4 2/5

The answer to this equation would be 4 2/5 or 4.4

Studentka2010 [4]

\bold{[ \ Answer \ ]}

\boxed{\bold{9x^{2} \ - \ 6xy \ + y^{2} }}

\bold{[ \ Explanation \ ]}

  • \bold{Find \ Expansion: \ (3x \ - \ y^{2} )}

\bold{----------------------}

  • \bold{[Apply \ Perfect \ Square \ Formula\ (\left(a-b\right)^2=a^2-2ab+b^2)] \ a \ = \ 3x, \ b \ = \ y}

\bold{\left(3x\right)^2-2\cdot \:3xy+y^2}

  • \bold{[Simplify \ \left(3x\right)^2-2\cdot \:3xy+y^2] \ 9x^2-6xy+y^2}

= \bold{9x^2-6xy+y^2}

\boxed{\bold{[] \ Eclipsed \ []}}
