Answer: option B. 2/11
Explanation:
1)
number of positive outcomes
Probability = ------------------------------------------
number of possible outcomes
2) Number of positive outcomes:
The positive outcome is choosing a T, given that there are two Ts, the number of positive outcomes is 2.
3) Number of possible outcomes
There are 11 letters, so the number of total outcomes is 11.
4) Therefore,
2
probability = ------

Answer:
1/(3x) =(x -2)/(4x^2 +9)
Step-by-step explanation:
The denominator cannot be factored further, so the final form will be ...
A/(3x) + (Bx +C)/(4x^2 +9)
The value of this is ...
(A(4x^2 +9) +(3x)(Bx +C))/(3x(4x^2 +9))
= ((3B+4A)x^2 +3Cx +9A)/(3x(4x^2 +9))
Equating coefficients gives ...
3B+4A = 7
3C = -6 ⇒ C = -2
9A = 9 ⇒ A = 1
Using the found value of A, we find ...
3B +4 = 7 ⇒ B = 1
Then the decomposition is ...
1.If AC = 5x + 2 and BD = 2x + 20, find BD. 5x+2=2x+20 D BD=216)+20=32 ... 5. In the accompanying diagram, ABCD is a rectangle. E is a point on CD:
When you plug in 3 in for y the equation is 3x + 6(3) = 24
3x + 18 = 24
subtract 18 from both sides
3x = 6
Isolate the x by dividing both side by 3
x = 2
