Answer: The average length of time that the 25 customers waited before leaving the bank. <u> e. Statistic</u>
The list of times for the 25 customers who left the bank. <u> f.Data </u>
All of the bank's customers <u> d. Population</u>
The 25 customers that the manager observed leave. <u> c. Sample</u>
The length of time a customer waits before leaving the bank. a. <u>Variable.</u>
The average length of time that all customers will wait before leaving the bank <u>a. Parameter</u>
Step-by-step explanation:
A data is a list of observations.
In statistics, a variable is an attribute that defines a person, place, thing, or thought.
A large group that have similar individuals as per the researcher's point of view is known as population, where its subset is known as sample.
The measure of certain characteristic in population is known as parameter, where for sample it is known as statistic.
Multiply the two brackets together
(2x-1)(x-2)
2x(x)(2x*-2)(-1*x)(-1*-2)
2x^2-4x-x+2
2x^2-5x+2
Answer is 2x^2-5x+2 - J
Answer:8:30 PM (20:30) Previous Day
Step-by-step explanation:
A polynomial is the sum of at least one term. For example, x^3+1 is a polynomial. A monomial is a polynomial with only one term, such as 2x^2.
A binomial is a polynomial with two terms, and a trinomial is one with three terms. The example you gave is a trinomial (which is also a polynomial).
Degree of a polynomial is the largest sum of variable powers in any term of the polynomial. So, for example, x^2 y has degree 3, and x^3+x^2 also has degree 3. A sixth degree polynomial would be x^6-2x+1, for example.
