Take 47,000/12
12 months in a year = $3917

(new -original)/original * 100
(36-20)/20 * 100
16/20 * 100
.8*100
80
80% increase
Z = (X-Mean)/SD
<span>z1 = (580-600)/20 = - 1 </span>
<span>z2 = (620-600)/20 = + 1 </span>
<span>According to the Empirical Rule 68-95-99.7 </span>
<span>Mean +/- 1*SD covers 68% of the values </span>
<span>Therefore, required percent is 68%
hopes this help :) :D :)</span>
