Answer:
a) What is the volume of water in ft?
We are given that The tub contains 100 gallons of water
So,
b)Find the weight of the water in units of Ibf.
Specific weight of water at 100° F =
Weight of water =
c)What is the total weight of tub plus human plus water?
Total weight = Weight of tub + weight of human + weight of water
d)What is the pressure on the floor in units of psi (Ibf/in2)?
1 feet = 12 inches
Area of floor =
Pressure =
Hence the pressure is 0.691 psi
Answer:
The probability that the person reaches home for the holidays is 0.94.
Step-by-step explanation:
A person wants to go home for Thanksgiving and he has booked a flight with US-Scareways.
It is provided that in 30 percent of the cases the company has canceled the flight you were on.
SO there is 70% chance of reaching home without any difficulties.
In case the flight is cancelled, then as a backup the person's friend Walter offers a ride home.
Walter also has a 80% chance of giving the ride. So there is 20% chance the person will not be able to reach hone if his flight gets cancelled.
Consider the tree diagram below.
The events are:
FC = flight is cancelled
FT = Flight is on time
H = reaches home
Compute the probability that the person reaches home as follows:
P (Reaching Home) = P (H|FC) × P (FC) + P (FT)
Thus, the probability that the person reaches home for the holidays is 0.94.
Answer:
Step-by-step explanation:
This equation is more intimidating than the problem you have to solve.
You know that the sine of everything is always between -1 and +1. So for the entire expression to be >= 0, the a*tan(pi/8) bit has to be 1 at least. Given this, we can forget about the sin(...) term of the equation for the remainder of solving it.
You already figured out that tan(pi/8) is sqrt(2)-1.
So what we're saying is a * (sqrt(2) - 1) has to be 1 at least.
If we solve a(sqrt(2)-1) >= 1 for a we get:
a = 1/(sqrt(2)-1)
