Answer:
What is 10% of 120?
Step-by-step explanation:
120 / 10 = 12
10% of 120 = 12
We have a match.
Let's do the others, just to be sure it's the only one.
10% of 12 = 1.2
25% of 120 = 30
25% of 120 = 3
So lets do it like this:
z = (X-Mean)/SD
<span>z1 = (8-12)/2 = - 2 </span>
<span>z2 = (16-12)/2 = + 2 </span>
<span>According to the Empirical Rule 68-95-99.7 </span>
<span>Mean more or less 2SD covers 95% of the values </span>
So t<span>he percentage of data points falling between 8 and 16 = 95%
</span>I hope this can help
As it is only 5, it is 5/1 so you do 5 x 3 = 15 then 1 x 4 = 4. So 15/4
