$2\frac{1}{4}$

Step-by-step explanation:

$(\frac{21}{16} *\frac{12}{9} )+(-\frac{3}{8} *-\frac{12}{9} )$

$\frac{252}{144}+\frac{36}{72}$

Before adding these fractions, simplify both fractions.

$\frac{21}{12} +\frac{3}{6}$

Still you can simplify.

$\frac{7}{4} +\frac{1}{2}$

Now let us add these fractions.

$\frac{7}{4} +\frac{1}{2} \\\\\frac{7}{4} +\frac{1*2}{2*2} \\\\\frac{7}{4} +\frac{2}{4} \\\\\frac{9}{4} \\\\2\frac{1}{4}$

Hope this helps you :-)

Let me know if you have any other questions :-)

Approximately 68% of a normal distribution lies within one standard deviation of the mean, so this corresponds to students with scores between (57.5 - 6.5, 57.5 + 6.5) = (51, 64)
