Answer:
Step-by-step explanation:
9-4(x-y)=2x+6
9 - 4x + 4y = 2x + 6
9 + 4y = 6x + 6
4y = 6x - 3
y = 3x/2 - 3/4
Answer: 0.2195
Step-by-step explanation:
Binomial distribution formula :-
, where P(x) is the probability of x successes in the n independent trials of the experiment and p is the probability of success.
Given : The probability of that the general population has blood type A = 
Sample size : n=6
Now, the probability that exactly three of them have blood type A is given by :-

Therefore, the probability that exactly three of them have blood type A = 0.2195
A difference in electric potential
10. angle APB = (1/2) arc AB
108 = (1/2) arc AB
multiply both sides by 2 to clear the fraction
216 = arc AB
11. Area of regular Octagon s = 5 in
A = (P * apothem)/2 => => If you divide the octagon into 8 triangles, the apothem is the perpendicular height of the triangle.
A = (5 * 8 * 6)/2
A = 120 in^2
Area of regular Hexagon s = 5 in
A = (5 * 6 * 4.3)/2
A = 129 in^2
