81 to the 4th root is 3 and 3 cubed is 27.
Start by finding the common denominators (in this case, 6)
So;
1/6x + 15/6 = -2/6
1/6x = -17/6
x = -17
Answer:
V = 32/3 pi
Step-by-step explanation:
The volume of a sphere is given by
V= 4/3 pi r^3
We know the radius is 2
V = 4/3 pi (2)^3
V = 4/3 pi (8)
V = 32/3 pi
In normal distribution, 68% of the values are within +_ 1 SD. That leaves 32% outside that range. Thus, 32 people with greater than 13, 100 people greater than 14 (200*0.68/2+32)
