Mathematics
1 answer:
Sedaia [141]3 years ago

False. You can find the solution more quickly by solving the system algebraically.

-4x + 2y = 18

Since y=-3x+4,
-4x + 2(-3x+4) = 18
-4x - 6x + 8 = 18
-10x = 10
x = -1
y = -3x+4 = 7

Given the declaration, where is the value 97 stored in the numbers array? int numbers[]={83, 62, 77, 97, 88};
Zepler [3.9K]
Let me help you!

Ok, so before I give you the answer, which is very simple, I will first show you how to answer questions like this in the future.

In the variable declaration, the array "numbers[]" has been declared as an integer. The values of the array "numbers[]" are: <span>83, 62, 77, 97, 88; respectively, the values are equivalent to: 0, 1, 2, 3, 4 which makes the range of array "numbers[]": 5.

To make it clearer:
</span>numbers[0] = 83
numbers[1] = 62
numbers[2] = 77
numbers[3] = 97 <---- This is what we are looking for!
numbers[4] = 88

*** By the way, when counting the range, we don't start at 1, we start at 0. That's why even if the range is 5, the last value is 4.

Therefore, the answer is: 3 or numbers[3].

Based on the 2017 season, the Houston Astros have a winning percentage of .623. Use the binomial model to find the probability t
Zigmanuir [339]

Answer: Your answer would be C) 32.1%

Step-by-step explanation:

With the number of successes needed to be 4 and the total amount of trials (games) for this to be achieved in being 6 you can calculate a percentage based on their currenting winning percentage of .623 (don't forget decimals can be percentages, just move the decimal point over) and you can input all of this into the binomial model equation to get your answer. Please do note also that it would be a different answer entirely if you were to use .500 (50%) as a winning percentage which would be the logical conclusion as any team has a 50/50 chance of winning a given game but instead the question is asking us to calculate this percentage off the already given winning percentage. After inputting the data into the model formula you can conclude the answer to be 32.1% chance of them winning 4 out of the next 6 games. I hope this has been of assistance to you :)

Have a wonderful rest of your day!
