Suppose U= {1, 2, 3, 4, 5, 6, 7, 8} is the universal set and P= {1, 2, 3, 4}. What is P?
Digiron [165]
Did you mean P' ? The letter P with a tick mark after it. If so, then start with set U and erase any number you find in set P
We start with
{1,2,3,4,5,6,7,8}
and we erase the following: 1,2,3,4
since those numbers are in set P
P = {1,2,3,4}
P ' = {5, 6, 7, 8}
<span>The set P' is the complement of set P. It is, in a sense, the opposite of set P. It contains everything that P doesn't have.</span>
Estimating the number of internet users in Europe by multiplying the ratio with the whole internet users
users in Europe = 9/40 × 2.1 billion
users in Europe = 9/40 × 2,100 million
users in Europe = (9 × 2,100)/40 million
users in Europe = 18,900/40 million
users in Europe = 472.5 million
The number of internet users in Europe is approximately 472.5 million at this time
The computer costs $304 now.
Step-by-step explanation:
Given,
Cost of computer = $400
First discount = 20%
Amount of discount = 20% of $400
Amount of discount = 
Amount of discount = $80
Price after first discount = 400-80 = $320
Additional discount = 5%
Amount of additional discount = 5% of price after first discount
Amount of additional discount = 
Amount of additional discount = $16
Final cost = 320-16 = $304
The computer costs $304 now.

Hello!
2.5 litres = 1,000 * 2.5 = 2,500 cubic cm
volume = π * radius2 * height
2,500 = π * r2 * 20
2,500 / 20π = r^2
(Square Root of) 2,500 / 20π = r^2
6.307 <span>centimeters </span>= r (Radius)
Hope this Helps! Have A Wonderful Day! :)
