(05.02) what is the value of the x variable in the solution to the following system of equations? 4x + 2y = 12 x – y = 3

 6

Step-by-step explanation:

The given system of equations :

Multiplying 2 to the both sides of equation (2)

Now, Add equation (1) and equation (3), we get

Put x=6 in (2), we get

Hence, the value of the x variable in the solution to the following system of equations =6

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
