The one with the highest numerator and denominator. 17/18
F(x) = 2x^2 + 5x
f(3b) = 2(3b)^2 + 5(3b) = 2(9b^2) + 15b = 18b^2 + 15b
Answer:
a) 0.3246
b) 0.0043
Step-by-step explanation:
- For player 1 ; Probability of winning = P(W) = 1/3
- Probability of loosing; P(winning) + P( Loosing) = 1
a) To find Find P(N <= 10) = P(2)+P(3)+P(4)+P(5)+P(6)+P(7)+P(8)+P(9)+P(10)
= (1/3)^2 + (1/3)^2 x 2/3 + (1/3)^2 x (2/3)^2 + (1/3)^2x (2/3)^3 + (1/3)^2 x (2/3)^4
X (1/3)^2 x (2/3)^5 + (1/3)^2 x (2/3)^6 + (1/3)^2 x (2/3)^7 + (1/3)^2 x (2/3)^8
= 0.3246
b) Find P(N = 10) = (1/3)^2 x (2/3)^8 = 0.0043

Answer:
x = 5
Step-by-step explanation:
The sides are in proportion.
The proportion is 20/36
The other sides must be in the same proportion: 5x / 45
5x/45 = 20/36 You can reduce the left side by dividing top and bottom by 5
1x / 9 = 20/36 You can reduce the right side by dividing by 4
x / 9 = 5/9 at this point you should be able to see that x = 5, because the denominators are the same.
That is the answer.
However you can extend this by cross multiplying
9x = 45 Divide by 9
x = 45/9
x = 5
