Answer:

-\dfrac{11}{12}

Step-by-step explanation:

\dfrac{\frac{5}{8}+\frac{3}{4}}{\frac{-2}{3}-\frac{5}{6}}

Find common denominators:

\dfrac{\frac{5}{8}+\frac{6}{8}}{\frac{-4}{6}-\frac{5}{6}}=

\dfrac{\frac{11}{8}}{\frac{-9}{6}}=

\dfrac{11}{8}\cdot -\dfrac{2}{3}=-\dfrac{11}{12}

Hope this helps!

Suppose that grades on a midterm and a final have a correlation coefficient of .5 and both exams have an average score of 75 and
Eva8 [605]

Answer:

85

Step-by-step explanation:

The correlation coefficient relates the standarized values of the midterms a final score in this way:

\frac{y - y^}{sy}  = r* \frac{x - x^}{sx}

where y is the final score that needs to be found, y^ is the average score on the finals, sy is the standar deviation for the scores on the finals, x is the midterm score, x^ is the average score on the midterms and sx y the standard deviation of the scores on the midterms.

If we issolate y on the equation and solve with the data we have, we get that:

r* \frac{x - x^}{sx}[/tex] = 0.5 * \frac{95 - 75}{10} = 1

y = 75 + 1*10 = 85

This means the predicted final score will be 85.
