Answer:
Happy Thanksgiving, my friends.
Step-by-step explanation:
The probability to choose letter n is

. After drawing letter n there left 25 letters and the probability to choose the letter w is

. After drawing two letters n and w there left 24 letters and then the probability to choose letter b is

. After drawing three letters n, w and b there left 23 letters, so the probability to choose letter t is

.
Using the product rule for probabilities, you can obtain that

.
The equation for surface area of a sphere is SA=4*pi*r^2
We can plug in what we know to solve for r
400=4*pi*r^2
100=pi*r^2 (divide out the 4)
100/pi=r^2 (divide out the pi)
√(100/pi)=r (square root of both sides)
r=5.6 rounded to the nearest tenth
I’m pretty sure it’s $16,425
Improper fraction would be 9/7
mixed number is 1 2/7
