1. All good teachers come to class on time. Professor Simon always comes to class on time. Therefore, Professor Simon must be a good teacher. Explanation:
Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
Addition
Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.
![Determine whether the following argument is valid or invalid. If it is
invalid, you must give an example of possibility in which the premises
could be true and the conclusion is false at the same time.
Example: Maria owns an iphone 11.
Rich people own iphone 11.
Therefore, Maria must be rich.
Explanation: Consider all the possibilities. The second premise, "Rich
people own iphone 11," does not exclude the possibility that some
people who are not rich own iphone 11 (i.e., Maria could have a rich
uncle who bought the iphone 11 for her.) If this possibility is true,
then both premises could be true, but the conclusion would be false.
Any argument in which it is possible to have true premises and a false
conclusion at the same time is invalid. Therefore, the argument is
invalid.
Please note (and this is very important!!): In showing how the argument
could be invalid, we did not deny the truth of premise one or two. We do not
show an argument to be invalid by saying one of the premises is false.
