Answer:
3
Step-by-step explanation:
D(1 , 1) to D'(3, 3)
so x (1 x 3)= 3
y (1 x 3) = 3
SF = 3
D(1 , 5) to D'(3, 15)
so x (1 x 3)= 3
y (5 x 3 ) = 15
SF = 3
Same on coordinate points B to B' and C to C'
so SF = 3
Ax^2+bx+c
if a=1, then
take 1/2 of b and square it
w^2-4w+c
b=-4
-4/2=-2, (-2)^2=4
add that
w^2-4w+4
(w-2)(w-2)
(w-2)^2
to make it into perfect squres, add 4
G = 6x
to solve for x divide both sides by 6
x = g/6
Answer:
55/2574 ≈ 2.18%
Step-by-step explanation:
There are a total of 13 people on the council.
The probability that the first person is a Democrat is 8/13.
The probability that the second person is a Democrat is 7/12.
The probability that the third person is a Republican is 5/11.
The probability that the fourth person is a Republican is 4/10.
The probability that the fifth person is a Republican is 3/9.
The total probability is:
P = (8/13) (7/12) (5/11) (4/10) (3/9)
P = 56/2574
P ≈ 0.0218
There is a 2.18% probability of selecting two Democrats and three Republicans.
