Answer: C
Step-by-step explanation: A = 10 for one person. B = 7.5 for one person. C = 6.67 for one person. D = 8.75 for one person. E = 10 for one person.
Out of all of these, C is the cheapest.
The handshake problem!
Each of the five will play against 4 others, but since A vs B can be considered the same game as B vs A, so there are 5*4/2=10 matches.
A function can be represented by equations and tables
- 4 users are logged in by 9am
- The domain is [3,23] and the range of the function is [3,4]
<h3>The number of users at 9am</h3>
The function is given as:

At 9am, x = 9.
So, we have:


Simplify

Approximate

Hence, 4 users are logged in by 9am
<h3>The domain</h3>
Set the radical to 0

Solve for x

The maximum time after midnight is 23 hours.
So, the domain is [3,23]
<h3>The range</h3>
When x = 3, we have:


When x = 23, we have:

So, the range of the function is [3,4]

Answer:
A
Step-by-step explanation:
8.5% of 81.42
8.5 81.42 692.07
------- X ---------- = -------------
100 1 100
divide 692.07/100 which gives you 6.9207
if you round it to the nearest hundredth you get 6.92
Answer:
Subtract c, then divide by m.
