Answer:
(x, y) = (10, - 1)
Step-by-step explanation:
given the 2 equations
3y = - 
x + 2 → (1)
y = - x + 9 → (2)
substitute y = - x + 9 into (1)
3(- x + 9) = - x + 2
- 3x + 27 = - x + 2
add x to both sides
- 
x + 27 = 2 ( subtract 27 from both sides )
- x = - 25
multiply both sides by 2 and divide by - 5
x = 10
solution (10, - 1)

Answer:
The correct answer: 0.05404
Step-by-step explanation:
Given:
Binomial distribution = x
n = 10
and p = 0.09
solution:
P(X=x) =1 0Cx*(0.09^x)*((1-0.09)^(10-x)) for x=0,1,2,...,10
So the probability is calculated by the Formula:
P(X>=3) = 1-P(X=0)-P(X=1)-P(X=2)
putting the given values in the formula
= 1-10C0*(0.09^0)*((1-0.09)^(10-0))-...-10C2*(0.09^2)*((1-0.09)^(10-2))
= 0.0540400
Thus, the correct answer: 0.05404
