x -3y = 4 multiplie both sides by -2 => -2x +6y = -8
2x +Qy = 8
-2x +6y = -8
2x +Qy = 8
------------------ assume the same terms
0 6y +Qy = 0
6y +Qy = 0
Qy = -6y divide both sides by y and will get
Q = -6
Answer:
0.29
Step-by-step explanation:
Given :
n : ___ 0 _____ 1 ____ 2 ____ 3 ____ 4
P(n) : 0.82___ 0.11 ___0.04 _0.02 ___0.01
The expected number of defect in a shipment can be obtained using the expected value formula :
Expected value, E(X) = Σx*p(x)
Σx*p(x) = (0*0.82) + (1*0.11) + (2*0.04) + (3*0.02) + (4*0.01)
E(X) = 0.29
Hence, the expected number of defect in shipment is 0.29
