Call the smaller angle as x, we have
x + (x + 20) = 180 \\ 2x + 20 = 180 \\ x = 80
so the smaller angle is 80° degree and the bigger one would be 100°

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 .

<u>Step-by-step explanation:</u>

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 :

<u>1. player chosen from type1</u>

<u>2. player chosen from type2</u>

<u>3. player chosen from type3</u>

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 .

4b<br> 6c for b = (-3) and c = 5
Annette [7]

Answer:

Today: Friday, 06 November 2020

Hour: 10.15 WIB (Indonesia)

<u>_______________________________</u>

so,

6c = 6 × 5 = 30

4b = 4 × (-3) = -12

Example:

4b - 6c

= 4(-3) - 6(5)

= -12 - 30

= - 42

4b + 6c

= 4(-3) + 6(5)

= -12 + 30

= 18
