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 :
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 :
⇒ 
⇒ 
⇒ 
∴ The probability of winning is 0.44 .
Answer:
If the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.
Hope this helps :D
Answer:
Average change in temperature is - 2.8 Fahrenheit per hour.
Step-by-step explanation:
Average change in temperature is the change in temperature divided by the time taken for the change.
Change in temperature = (-11.2) F- 0 F
= -11.2 F
Time taken for the change in temperature = 10 pm - 6 pm
= 4 hours
Average change in temperature = Change in temperature / time taken for the change
= 
= - 2.8 Fahrenheit per hour

Step-by-step explanation:
<u>Step 1: Define Equation</u>
3.5(x + 12) = -2x + 18
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 3.5: 3.5x + 42 = -2x + 18
- Add 2x on both sides: 5.5x + 42 = 18
- Isolate <em>x</em> term: 5.5x = -24
- Isolate <em>x</em>: x = -4.36364
Answer:
C
Step-by-step explanation:
Here, we want to interpret what is meant by m(10) = k
Originally M(n) represents the fee in dollars for an nth drive
So M(10) will represent the fee in dollars for the 10th drive and is equal to K dollars
Correct option is C
