2. Now use calculator..
2nd>vars>normalcdf
Fill it in with your data then click paste.
(IF YOU HAVE TO SHOW YOUR WORK WRITE OUT WHATS GIVEN ON YOUR CALC.. normalcdf(5.550,5.790,5.670,.062) )
= .9470691924
Rounded to four decimals..
You do 49.50 times 4% equals $1.98. You than add $49.50 plus $1.98 that equals to $51.48 the total you paid for the shoes
2/5 + 2/4 = 8/20 + 10/20 = 18/20 = 9/10
The quadratic formula is

. With the values from this equation plugged in, it looks like this:

The solution is x = - 3/2
