Arlecino [84]

Answer:

Step-by-step explanation:

Given that:

Amount earned when a student does comminty service = $5

Number of students in club = 12

Amount earned E, is a function of number of members (n) who does community service.

Hence,

E = n * amount earned per member

Is 24 a possible output?

To test, then E = 24

24 = n * 5

24 = 5n

24/5 = 5n/5

4.8 = 5

Hence, 24 is not a possible output, be use number of membwra cannot be a decimal

Doss [256]

Answer: The coefficient of determination = 0.6291

Step-by-step explanation:

Given: Total variation is 24.488, the explained variation is 15.405, and the unexplained variation is 9.083.

The coefficient of determination is computed as:

$\text{ coefficient of determination} =\frac{\text{explained variation }}{\text{total variation}}$

Substituting given values, we get

$\text{coefficient of determination} =\frac{15.405}{24.488}$

$=0.6291$

Therefore, the coefficient of determination = 0.6291

Answer:

<em>See below</em>

Step-by-step explanation:

In this example we are to consider the equation 2x - 5 = 4x + 12, and are asked to solve for x. Well let us take the first approach, a mathematical one;

$2x - 5 = 4x + 12,\\- 5 = 2x + 12,\\- 17 = 2x,\\\\x = - 17 / 2 = - 8.5\\\\Conclusion, x = - 8.5 / x = - 8 and 1 / 2$

Now consider the explanation, " talking over a phone to a friend. "

First you would subtract 2x on either side of the equation, canceling the 2x on one side, and subtracting 2x from 4x on the other, resulting in the simplified equation - 5 = 2x + 12. Subtracting 12 from either side we cancel the 12 on one side, and subtract - 12 and - 5 on the other. We now get - 17 = 2x. Dividing 2 on either side, x = - 8.5!
