  2. SAT Subject Test in Mathematics Level 2 - Wikipedia

    en.wikipedia.org/wiki/SAT_Subject_Test_in...

    Compared to Mathematics 1, Mathematics 2 was more advanced. Whereas the Mathematics 1 test covered Algebra II and basic trigonometry, a pre-calculus class was good preparation for Mathematics 2. [2] On January 19, 2021, the College Board discontinued all SAT Subject tests, including the SAT Subject Test in Mathematics Level 2. This was ...

  3. Modulo - Wikipedia

    en.wikipedia.org/wiki/Modulo

    In computing, the modulo operation returns the remainder or signed remainder of a division, after one number is divided by another, called the modulus of the operation.. Given two positive numbers a and n, a modulo n (often abbreviated as a mod n) is the remainder of the Euclidean division of a by n, where a is the dividend and n is the divisor.

  4. SAT Subject Test in Mathematics Level 1 - Wikipedia

    en.wikipedia.org/wiki/SAT_Subject_Test_in...

    The SAT Subject Test in Mathematics Level 2 covered more advanced content. Generally you need to have completed a semester of a pre-calculus class with a solid “B” or better to feel comfortable on the Math 1, whereas the content of the Math 2 test extends through Algebra II and basic trigonometry, precalculus, and basic calculus.

  5. Monty Hall problem - Wikipedia

    The answer to the first question is ⁠ 2 / 3 ⁠, as is shown correctly by the "simple" solutions. But the answer to the second question is now different: the conditional probability the car is behind door 1 or door 2 given the host has opened door 3 (the door on the right) is ⁠ 1 / 2 ⁠.

  6. History of free and open-source software - Wikipedia

    Examples include Python in 1991, Ruby in 1995, and Scala in 2003. In recent times, the most notable exceptions have been Java, ActionScript, C#, and Apple's Swift until version 2.2 was proprietary. Partly compatible open-source implementations have been developed for most, and in the case of Java, the main open-source implementation is by now ...

    Object-oriented analysis and design (OOAD) is a technical approach for analyzing and designing an application, system, or business by applying object-oriented programming, as well as using visual modeling throughout the software development process to guide stakeholder communication and product quality.

  8. Protein engineering - Wikipedia

    It has been used to improve the function of many enzymes for industrial catalysis. [2] It is also a product and services market, with an estimated value of $168 billion by 2017. [3] There are two general strategies for protein engineering: rational protein design and directed evolution. These methods are not mutually exclusive; researchers will ...

  9. EWMA chart - Wikipedia

    The first parameter is λ, the weight given to the most recent rational subgroup mean. λ must satisfy 0 < λ ≤ 1, but selecting the "right" value is a matter of personal preference and experience. One 2005 textbook recommends 0.05 ≤ λ ≤ 0.25, [2]: 411 while a 1986 journal article recommends 0.1 ≤ λ ≤ 0.3. [3]
