You enter a chess tournament where your probability of winning a game is 0.3 against half the players (call them type 1), 0.4 ag

Doss [256]

The probability of winning is 0.44 .

Step-by-step explanation:

Here it's given that , You enter a chess tournament where your probability of winning a game is 0.3 against half the players (call them type 1), 0.4 against a quarter of the players (call them type 2), and 0.5 against the remaining quarter of the players (call them type 3). You play a game against a randomly chosen opponent. More precisely :

$Probability(type1) = 0.3\\Probability(type2) = 0.4\\Probability(type3) = 0.5\\\\Probability(winning) = w$

Now, we choose a random opponent and we need to find probability of winning which is possible as :

1. player chosen from type1

2. player chosen from type2

3. player chosen from type3

Combining all cases we get :

⇒ $w = type1(1-type2)(1-type3) + (1-type1)type2(1-type3) + (1-type1)(1-type2)type3$

⇒ $w = 0.3(0.6)(0.5)+0.7(0.4)(0.5)+0.7(0.5)(0.6)$

⇒ $w = 0.44$

∴ The probability of winning is 0.44 .

Find a third-degree polynomial equation with rational coefficients that has roots –5 and 6 + i.

Vitek1552 [10]

The coefficients of the polynomial are rational, which means that any non-real roots occur alongside their complex conjugates. In this case, 6+i is a root, so 6-i is also a root.

So the simplest polynomial you can build with these roots is

(x - (-5)) (x - (6 + i )) (x - (6 - i )) = x ^3 - 7x ^2 - 23x + 185

(first choice)

Nikki just graduated from high school and would like to buy a car. If she received $3000 in graduation gifts from family friends

svetlana [45]

Answer:

$3450

Step-by-step explanation:

Here, P = $3000, N = 1.5 years, R = 10%

$SI = \frac{PNR}{100} \\ \\ SI = \frac{3000 \times 1.5 \times 10}{100} \\ \\ SI = 450 \\ \\$

Amount of down payment

= $3000 + $450

= $3450
