question:The average score of a cricketer for some matches is 38.9 runs. If the average for the first 6 matches is 41 and the average for the last 4 matches is 35.75, how many matches were played in total?

answer:Let's denote the total number of matches played by the cricketer as ( n ). The average score for all the matches is 38.9 runs. Therefore, the total runs scored in all the matches is ( 38.9 times n ). The average score for the first 6 matches is 41 runs. Therefore, the total runs scored in the first 6 matches is ( 41 times 6 ). The average score for the last 4 matches is 35.75 runs. Therefore, the total runs scored in the last 4 matches is ( 35.75 times 4 ). Since the first 6 matches and the last 4 matches are part of the total matches, we can set up the following equation: [ 41 times 6 + 35.75 times 4 = 38.9 times n ] Now, we can solve for ( n ): [ 246 + 143 = 38.9 times n ] [ 389 = 38.9 times n ] [ n = frac{389}{38.9} ] [ n = 10 ] Therefore, the total number of matches played is boxed{10} .

question:Create a Python function that takes a boolean value and returns the corresponding character: '1' if True, and '0' if False. The function should not use an if statement or any other conditional branching. Use a conditional expression or a single line statement to achieve this. Your solution should be concise and readable. Your code should pass the following assertion: ```python assert boolean_to_character(False) == '0' ```

answer:To complete this task, we can utilize a conditional expression or a single line statement to achieve the desired functionality. The conditional expression can be written as `char = '1' if value else '0'`, which assigns '1' to `char` if `value` is True, and '0' otherwise. This ensures that the returned character matches the boolean value. The solution can be implemented as follows: ```python def boolean_to_character(value: bool) -> str: return '1' if value else '0' ``` The conditional expression allows us to assign the correct character based on the boolean value. It is concise and readable, and follows the provided instructions.

question:Solve the following system of linear equations: 4x + 2y = 10 2x - 3y = -8

answer:To solve this system of linear equations, we can use the method of substitution or elimination. In this case, we'll use the elimination method. First, we'll multiply the second equation by 2 to make the coefficients of x in both equations equal: 4x + 2y = 10 (Equation 1) 4x - 6y = -16 (Equation 2, after multiplying by 2) Now, we'll subtract Equation 1 from Equation 2 to eliminate x: (4x - 6y) - (4x + 2y) = -16 - 10 -8y = -26 Now, we'll solve for y: y = -26 / -8 y = 13/4 Now that we have the value of y, we can substitute it into either Equation 1 or Equation 2 to solve for x. We'll use Equation 1: 4x + 2(13/4) = 10 4x + 13/2 = 10 To solve for x, we'll first convert all terms to have a common denominator, which is 4: 8x + 13 = 20 Now, we'll subtract 13 from both sides: 8x = 7 Finally, we'll divide by 8 to get the value of x: x = 7/8 So, the solution to the system of linear equations is x = 7/8 and y = 13/4.
