Mu=80, sigma=39, X=85
Z=(X-mu)/sigma = 5/39=0.128=0.13
P(X<=85)= 0.5517 (from Z-table)
so, P(X>85)=1-0.5517=0.4483 approx. thats 44.8% probability.
Answer:
The x-coordinate of the solution is x=3
Step-by-step explanation:
we have
------> equation A
------> equation B
Solve the system of equations by substitution
Substitute equation B in equation A and solve for x
Find the value of y
------> 
The solution of the system of equations is the point (3,2)
therefore
The x-coordinate of the solution is x=3

Answer:
4,1
Step-by-step explanation:
The formula for the law of sines is:
sin(A)/a = sin(B)/b = sin(C)/c
Big letters denote angle measures while smaller letters denote side lengths.
