Answers

Answer 1
Answer:

John Dalton (1766 - 1844) was an English chemist who is primarily known for his atomic theory, which although it is about two centuries old and has progressed in the meantime, is still valid. According to his theory, all elements, matter, are made of atoms, and that all atoms in the given element have the same mass and property, while the compounds are formed from several different types of atoms, where the chemical reaction of two or more elements represents the rearrangement of atoms.

The answer is: B)

Answer 2

Let's say another friend of yours says that they're going to see the new horror film that recently came out, if you aren't a fan of horror films then you can tell that you will be unhappy if you go with that friend.  

A change in the value of an objective function coefficient does not change the optimal solution.True or False

Answers

It is accurate to say that the optimal solution is unaffected by changes in the value of an objective function coefficient.

What is coefficient?

  • A coefficient refers to a number or quantity placed with a variable. It is usually an integer that is multiplied by the variable and written next to it. The variables which do not have a number with them are assumed to be having 1 as their coefficient. For example, in the expression 3x, 3 is the coefficient of x but in the expression x2 + 3, 1 is the coefficient of x2. In other words, a coefficient is a multiplicative factor in the terms of a polynomial, a series, or any expression. Observe the following expression which shows that 5 is the coefficient of x2 and 8 is the coefficient of y.
  • A coefficient can be positive or negative, real or imaginary, or in the form of decimals or fractions. Another definition of coefficient says, “Any number with which we multiply a variable." For example, in the term 9.3x, 9.3 is the coefficient of the variable x, and in -5z, -5 is the coefficient.
