What is the solution to the following system of equations? 4x + 2y = 12 x − y = 3 (3, 0) (0, 3) (0, −3) (2, 3)
1 answer:
Answer: First Option
(3, 0)
Step-by-step explanation:
We have the following system of equations:
To find the solution of the system of linear equations multiply the second equation by -4 and add it to the first equation
--------------------------------------
Now substitute the value of y in the first or second equation:
The solution is: (3, 0)

Answer:
a) 0.75
b)5.05
c)0.02
Step-by-step explanation:
a)
P(Y>5)=?
This part is solved in the given picture.
b)
The mean of a uniform distribution is (a+b)/2.
Where a=4.95 , b=5.15.
E(Y)=(4.95+5.15)/2
E(Y)=10.1/2
E(Y)=5.05.
c)
The variance of a uniform distribution is (b-a)²/2.
V(Y)=(5.15-4.95)²/2
V(Y)=0.2²/2
V(Y)=0.04/2
V(Y)=0.02.
