A recent article in an educational research journal reports a correlation of +0.8 between math achievement and overall math aptitude. It also reports a correlation of -0.8 between math achievement and math anxiety. Which of the following interpretations is the most correct? The correlation of +0.8 is just as strong as the correlation of -0.8 . The correlation of +0.8 indicates a stronger relationship than the correlation of -0.8 . It impossible to tell which correlation is stronger.

\( \begin{array}{l} F_{y}=F \sin \theta \\ \text { Putting values, we get: } \\ F_{y}=50 \sin 30 \\ F_{y}=25 \mathrm{~N}\end{array} \)

\( \left. \begin{array} { l }{ 6 \div \frac { 3 } { 4 } = \ldots } \\ { = } \end{array} \right. \)

Lors des soldes d'hiver, un magasin offre un rabais de \( 20 \% \) sur tous ses articles Combien paie-t-on alors un manteau coûtant normalement 240 francs?

\( \frac { 57 } { 100 } ; \frac { 243 } { 10.000 } ; \frac { 131 } { 1.000 } ; \frac { 17 } { 1.000 } ; \frac { 231 } { 100 } ; \frac { 74 } { 10 } \)

\( 2-\frac{x+2}{x-3}-\frac{x-6}{x+3} \) canbe written as a single fraction in the form \( \frac{a x+b}{x^{2}-9} \) where \( a \) and \( b \) are integers. Work out the value of \( a \) and the value of \( b \).
