Answer: 70% chance of winning
Step-by-step explanation: What is your question? Are you trying to ask the probability of winning? (I will assume this and answer)
The whole case of selecting to numbers : 5C2 = 5 X 4 / 2 = 10
the cases of getting a odd sum : select 1 odd number and 1 even number
=> select 1 odd number : 7 or 9 => 2 cases
=> select 1 even number: 4,6,8 => 3 cases
you multiply 2 and 3 and divide it by 2 because order doesn't matter
so the answer is 1 - (3/10) = 0.7
The player in the game has an equal chance of winning or losing.
In this problem, we are given a box containing five slips of paper, each with a number written on it. The first player draws two slips and adds the two numbers together. To determine if the player wins or loses, we need to determine if the sum of the two numbers is even or odd.
To solve this problem, we can list all the possible pairs of numbers and find out if the sum of each pair is even or odd. If the sum is even, the player wins; if the sum is odd, the player loses. We can do this by considering the possible outcomes:
From the listed outcomes, we can see that there are 5 even sums and 5 odd sums.
Therefore, the player has an equal chance of winning or losing in this game.

B) 80.8
C) 81.7
D) 82.5
Answer:
The average of the whole class is 80.8.
The correct answer is B)
Step-by-step explanation:
To solve this problem, it is very important to understand the phrase: "Ten students had an average of 88". Let's see an example.
Imagine that three students in the class took a test and their scores were: 80, 89 and 95. To calculate the average of they three we must divide the sum of the scores by the total number of scores.
The previous value is the average of the three students. Now, if we say that each student got 88, the average would be 88.
The previous expression could be simplified as:
Where, the number 3 means the number of students.
With that in mind, the phrase "Ten students had an average of 88" could be written as:
On the other hand, the phrase "The other students had an average of 76" means that from the 25 students, 15 students got 76 (25 - 10 = 15), and could be written as:
Finally, to calculate the total average of the 25 students we must divide the sum of the scores of all students by the total number of scores. The sum would be: 88+88+88+88+88+88+88+88+88+88+76+76+76+76+76+76+76+76+76+76+76+76+76+76+76, which equals . The total number of scores would be: 25.
Thus, the average of the whole class is 80.8. The correct answer is B)
The answer is B. 80.8
Answer:
8a+1=33
Step-by-step explanation:
you can solve 3a-2=10 by simplifying to 3a=12, so a=4. Then you replace the a in 8a+1 with 4 to get 32+1, which is 33
Answer:
33
Step-by-step explanation:
3a-2= 10
3a=12
a=4
in this equation a=4 so you substitute that value into the other equation
8(4) +1=33
Answer: 9/16
Step-by-step explanation:
First, we must find the answer to the hidden question: How much cheese did Mr. Sand put in the container without the weight of the container? We can rename 1 1/4 to 1 4/16, so 1 4/16 - 1/16 = 1 3/16
Now we must find the amount of cheese that needs to be added. We can rename 1 3/4 to 1 12/16 by multiplying it by 4/4. 1 12/16 - 1 3/16 = 9/16
9/16 pound of cheese should be added to get the amount Veronica asked for.
