The answer is <span>dihedral angle. It is the angle between two planes that intersected. It can be used in chemistry also in which it is the angles between two bonds and also in aerodynamics in which it is the upward angle that the wings are contacting with.</span>
So u can see a rectangle and a triangle
Area of the rectangle is 7 x 12 = 84ft
Area of the triangle= base x height divided by 2
So 6 x 12 = 72. 72/2 = 36ft
Then u add both areas
36 + 84 = 120ft
Hope this helps!
The constant is .o5 and that would be it all the time
Answer: 0.8413
Step-by-step explanation:
population mean = 3
population variance = 0.03
sd (standard deviation) = √0.03
Let x = sample mean
x has a mean of 3 and sd of √0.03/√3 = √0.01 = 0.1
And we can aprox the sample mean distribution using a normal distribution
Note: this approximation maybe is not so good (n = 3)
with mean = 3 and sd = 0.1
z = (x-3)/0.1 has a standard normal distribution
P(x<3.1) = P(z<(3.1-3)/0.1) = P(z<1) =0.8413
