Which statement correctly assigns x as an infinite number

For a system of two linear equations and two variables, there can be no solution, exactly one solution, or infinitely many solutions (just like for one linear equation in one variable). If the two equations are in standard form (both variables on one side and a constant on the other side), then the following are true: 1) lf the ratio of the coefficients on the x’s is unequal to the ratio of the coefficients on the y’s (in the same order), then there is exactly one solution. 2) lf the coefficients ratios mentioned in 1) are equal, but the ratio of the constant terms is unequal to the coefficient ratios, then there is no solution. 3) lf the coefficient ratios mentioned in 1) and the ratio of the constant terms are all equal, then there are infinitely many solutions. If you have ended with an expression like 8 = 3, there is an error in your solution or, if you are working with a system of equations, then there is no solution that satisfies all the equations in the system. 8 = 3 is not an answer. It either means that you need to review your work or that there is no answer. Sorry, repost as I posted my first answer in the wrong box. According to a Wikipedia page about him, Sal is: "[a]n American educator and the founder of Khan Academy, a free online education platform and an organization with which he has produced over 6,500 video lessons teaching a wide spectrum of academic subjects, originally focusing on mathematics and sciences." So technically, he is a teacher, but maybe ...

Quiz on Data types in Python 1.Which statement accurately defines the bool class? • Zero values are considered True always • Zero values are considered True some times • Bool class is a subclass of array class • Boolean Not returns False if the operand is True • Boolean first returns False then the True value Show Answer Answer: 1)Without an argument, an array of size 0 is created; contains a sequence of integers 0-255 12.Which statement creates the bytes literal when run? • bytes_literal = bytes.str.count(0x54) • bytes_literal = bytes.encoded.count(0x54) • bytes_literal = b'Copyright \xc2\xa9' • bytes_literal = bytes(str_literal,'utf-8') Show Answer Answer: 3)a.union(b) - a.intersection(b) Quiz on Loops & Conditionals in Python 1.What is the output of the following code? count = 0 while count < 2: print (count, " is less than 2") count = count + 2 else: print (count, " is not less than 2") • 1 is less than 2; 3 is not less than 2 • 2 is not less than 2 • Error • 0 is less than 2; 2 is not less than 2 Show Answer

Which datatype is represented by int in Python 3? Long Which statement accurately defines the bool class? Boolean not returns false…. Equivalent operation for function pow(x , y) is __. X**y What is the output of max('Infinity')? Y Which statement creates the bytes literal when run? bytes_literal = b'Copyright \xc2\xa9' The class which provides immutable sequence of elements tuple Which statements prevent the escape sequence interpretation? r’… bytearray provides an mutable sequence (making it modifiable) true

\( \newcommand\), then the following sentence is a statement. For each real number \(x\), \(x^2 > 0\). The phrase “For each real number x” is said to quantify the variable that follows it in the sense that the sentence is claiming that something is true for all real numbers. So this sentence is a statement (which happens to be false). Definition: universal quantifier The phrase “for every” (or its equivalents) is called a universal quantifier. The phrase “there exists” (or its equivalents) is called an existential quantifier. The symbol \(\forall\) is used to denote a universal quantifier, and the symbol \(\exists\) is used to denote an existential quantifier. Using this notation, the statement “For each real number \(x\), \(x^2\) > 0” could be written in symbolic form as: \((\forall x \in \mathbb. So these are all true statements. Negations of Quantified Statements In Preview Activity \(\PageIndex\), we wrote negations of some quantified statements. This is a very important mathematical activity. As we will see in future sections, it is sometimes just as important to be able to describe when some object does not satisfy a certain property as it is to describe when the object satisfies the property. Our next task is to learn how to write negations of quantified statements in a useful English form. We first look at the negation of a statement involving a universal quantifier. The general form for such a statement can be written as (\(\forall x \in U\)) (\(P(x)\)), where \(P...

Here is an example of an indefinite loop implemented by a while loop. double r = Math.random(); while (r < 0.5) Recall that Math.random() generates a random double between 0 and 1. The code initializes r to a random number. If r<0.5, then another random number is assigned to r, and the flow of control goes back to the test. This code will loop as long as r<0.5. Because of the randomness, we don't know how many times the loop will be executed. Activity: Simple while loop Implement a program including the above while loop. Print out every value that is assigned to r. Add a counter to count how many times the body of the loop is executed. Run the program several times to see how its behavior varies. Behavior of While Loops A while loop repeatedly executes its body as long as its test is true. The syntax of the ...
