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

Step-by-step explanation:
We can calculate the value of y by using the Euclidean theorem
y^2 = 20 × 4
y^2 = 80
y = 4√5
Answer:
Let width = l
Therefore, length = 3l
Perimeter = 2(l+b)
48 = 2(l+3l)
48 = 2× 4l
48 = 8l
8l = 48
l = 48/8
l = 6
Width = 6
Therefore, length = 3×6
= 18
Area = l×b
= 18×6
= 108

Answer:
Probability = 0.135
Step-by-step explanation:
Prob (one person doesn't file claim) = 2 / 3 = 0.67
Prob (5 people don't file claim) = p1 doesn't & p2 doesn't ...& p5 doesn't , ie = 0.67 x 0.67 x 0.67 x 0.67 x 0.67
= 0.67^5
= 0.135
