Answer:
(-12,11)
Step-by-step explanation:
x + 2y = 10
3x + 4y = 8
(-2)x + (-2)2y = (-2)10
3x    + 4y       = 8
-2x - 4y = -20
3x  + 4y = 8
Add to eliminate:
x = -12
Substitute x to solve y:
x + 2y = 10
(-12) + 2y = 10
-12 + 2y = 10
2y = 10 + 12
2y = 22
y = 22 ÷ 2
y = 11
Check:
x + 2y = 10
(-12) + 2(11) = 10
-12 + 22 = 10
10 = 10

Answer:
The probability that a randomly selected woman has red/green color blindness is 0.9914
Step-by-step explanation:
Given that the proportion of women having red/green color blindness is 0.86%
Represent that with p

Convert proportion from percentage to decimal; 


In probability; opposite probabilities add up to 1;
Let the probability that a woman selected have red/green color blindness be represented with q;

Subtract p from both sides


Substitute 0.0086 for p


<em>Hence, the probability that a randomly selected woman has red/green color blindness is 0.9914</em>
