Determine whether a number is rational or irrational by writing it as a decimal. See

The rational numbers and irrational numbers make up the set of real numbers. See
[link] . A number can be classified as natural, whole, integer, rational, or irrational. See

The order of operations is used to evaluate expressions. See

The real numbers under the operations of addition and multiplication obey basic rules, known as the properties of real numbers. These are the commutative properties, the associative properties, the distributive property, the identity properties, and the inverse properties. See

Algebraic expressions are composed of constants and variables that are combined using addition, subtraction, multiplication, and division. See
[link] . They take on a numerical value when evaluated by replacing variables with constants. See

Formulas are equations in which one quantity is represented in terms of other quantities. They may be simplified or evaluated as any mathematical expression. See

Is
an example of a rational terminating, rational repeating, or irrational number? Tell why it fits that category.
irrational number. The square root of two does not terminate, and it does not repeat a pattern. It cannot be written as a quotient of two integers, so it is irrational.
What do the Associative Properties allow us to do when following the order of operations? Explain your answer.
The Associative Properties state that the sum or product of multiple numbers can be grouped differently without affecting the result. This is because the same operation is performed (either addition or subtraction), so the terms can be re-ordered.
Step 1: Find the mean. To find the mean, add up all the scores, then divide them by the number of scores. ...
Step 2: Find each score's deviation from the mean. ...
Step 3: Square each deviation from the mean. ...
Step 4: Find the sum of squares. ...
Step 5: Divide the sum of squares by n – 1 or N.
The sample of 16 students is taken. The average age in the sample was 22 years with astandard deviation of 6 years. Construct a 95% confidence interval for the age of the population.
Bhartdarshan' is an internet-based travel agency wherein customer can see videos of the cities they plant to visit. The number of hits daily is a normally distributed random variable with a mean of 10,000 and a standard deviation of 2,400
a. what is the probability of getting more than 12,000 hits?
b. what is the probability of getting fewer than 9,000 hits?
