lakkis [162]

To find r, first write out the equation:
$\frac{3r+4}{2} =5$

$3r = 6$
Divide both sides by 3:
$r=2$

The answer to this problem is r = 2. Hope this helps and have a phenomenal day!

Find the z-score such as 88% of the area under the normal curve is to the left of the z-score

If you have a calculator with statistical functions, that's the way to go.

On my TI-83, I typed in invNorm(0.88) and got the result z = 1.17.
