To obtain the numerical value of the algebraic expression,
one must substitute in the same, the values of "x" and "a" respectively.
Answer:
Step-by-step explanation:
(i) x+2y=4
(ii) x=4-2y
(iii) 2x-2y=5
substituting (ii) in (iii)
2x-2y=5
2(4-2y)-2y=5
8-4y-2y=5
-6y=5-8
-6y=-3
(iv) y=
substituting (iv) in (ii)
x=4-2y
x=4-2×
x=4-1
x=3
∴ B.(3,)

Answer:
1.4
Step-by-step explanation:
Given the probability distribution :
X _____ 0 ____1 ____ 2 ____ 3 ____4
P(x) _ 0.16 _ 0.41 _ 0.32 __ 0.09 __ 0.02
Expected number of people waiting in line :
E(X) = Σ(x * p(x))
E(X) = (0*0.16) + (1*0.41) + (2*0.32) + (3*0.09) + (4*0.02)
E(X) = 1.4
