Answer:
900
Step-by-step explanation:
The ratio of the number of people who own a smartphone to the number of people who a flip phone is 5:3.
Let the number of people who own a flip phone=x
If 600 more people own a smartphone than a flip phone, then the number of people who own a smartphone=x+600
To find x, we express the ratio and population as an equality.
5:3=x+600:x
Expressing the ratios as fractions would give:
Next, we cross multiply
5x=3(x+600)
Open the brackets by expansion.
5x=3x+(3 X 600)
5x=3x+1800
Subtract 3x from both sides.
5x-3x=3x-3x+1800
2x=1800
Divide both sides by 2
x=900.
Since x=900, the number of people who own a flip phone is 900.
<h3>AUB = { 2, 3, 4, 6, 8, 9, 10, 12}</h3>
<em><u>Solution:</u></em>
The complete figure of question is attached below
From figure,
Write all elements from set A
A = {3, 6, 9, 12}
Write all elements from set B
B = {2, 4, 6, 8, 10, 12}
AUB means A union B
AUB means set of all the numbers combined with set A and set B
Combine set A and B
AUB = { 2, 3, 4, 6, 8, 9, 10, 12}
Thus AUB is found
