Answer:
A. 2x
Step-by-step explanation:
The slope is y values over x values
(0,0)
(1,2)
2-0 over 1-0
2/1 = 2
I think it’s D but I’m sure look up different math apps
Answer:
x = 2.13 × 10^11
Approximately 2.13 × 10^11 mails were processed in 2006
Completed question;
There were approximately 1.6 * 10^11 pieces of mall processed by the United States Postal
Service in 2012. This is about 75% of the number of pieces of mail processed in 2006.
Approximately how many pieces of mail were processed by the United States Postal Service in
2006
Step-by-step explanation:
Let x represent the number of mails processed in year 2006
Given;
Number of mails processed in 2012 N = 1.6 × 10^11
Number of mails processed in 2012 N is about 75% of the number of pieces of mail processed in 2006.
So;
N = 75% of x
N = 0.75x
x = N/0.75
x = (1.6 × 10^11)/0.75
x = 2.13 × 10^11
Approximately 2.13 × 10^11 mails were processed in 2006
0.1[x+250]=5000
10(0.1[x+250]=5000
1[x+250]=50,000
x+250=50,000
-250 -250
x = 49,750
Using the permutation formula, it is found that the people can be chosen for the roles in 6840 ways.
The order in which the people are chosen is important, as there are different roles, hence the <em>permutation formula</em> is used.
<h3>What is the permutation formula?</h3>
The number of possible permutations of <u>x elements from a set of n elements</u> is given by:
In this problem, 3 people will be chosen from a set of 20 people, hence the number of ways is given by:
