6 phone numbers are possible for one area code if the first four numbers are 202-1
<u>Solution:</u>
Given that, the first four numbers are 202-1, in that order, and the last three numbers are 1-7-8 in any order
We have to find how many phone numbers are possible for one area code.
The number of way “n” objects can be arranged is given as n!
Then, we have three places which changes, so we can change these 3 places in 3! ways
Hence 3! is found as follows:
So, we have 6 phone numbers possible for one area code.
Answer:
5 days
Step-by-step explanation:
Answer:
B. It can only be used for one variable at a time
Step-by-step explanation:
Simulation can accommodate multiple variables at a time. The variables could be constraints such as time, amount, quantity, duration. A range of expected values must either be developed or provided for the variables before simulation models can then be applied to these ranges to generate a distribution of NPVs.
A plane consists of an infinite set of points.
A point's location on the coordinate plane is indicated by an ordered pair, (x, y).
Step-by-step explanation:
The undefined terms in geometry are points, lines and planes.
- A point's location on the coordinate plane is indicated by an ordered pair, (x, y). TRUE. In R², the ordered pairs (x,y) is used to defined the location of a point.
- The second statement is false because a point has no dimension.
- The third statement is also false because a line has only one dimension which is length.
- The fourth statement is not true because distance between two points must have a beginning and an end.
- A plane consists of an infinite set of points. TRUE .The plane is a home of infinitely many points.
