Conclusion: young people like condiments.
First, let's convert things into percentages, since the number in each age category is different. There are 143 in "Under 18", 233 in "18 to 40", 161 in "40 to 60", and 122 in "over 60".
Of the under 18s: 71 of 143 = 49.7% order three or more.
Of the 18-40s: 87 of 233 = 37.3% order three or more.
Of the 40-60s: 47 of 161 = 29.2% order three or more.
Of the 60 and ups: 28 of 122 = 23.0% order three or more.
The older you are, the less likely you are to order lots of condiments.
Because empty set has no element which automatically make it a subset of every set.

Answer:
75 percent of 64 = 48
Step-by-step explanation:
Let that number be x.
"I multiply a number by four" Can be represented by 4x.
"Then I add one" means that to 4x, you added 1. So it's 4x + 1
"The answer is 33" So 4x + 1 = 33.
We need to solve for x.
4x + 1 = 33
First, subtract 1 from each side to have the variable on a side and the number on the other:
4x + 1 - 1 = 33 - 2
4x = 32
Divide both sides by 4 to get the variable x alone on a side and its value on the other side:
(4x)/4 = 32/4
x = 8
You can recheck your answer (very important):
4x = 8*4 = 32
4x + 1 = 32 + 1 = 33
The answer has been approved.
Hope this Helps! :)
The positive values of M and N are; 3.6 and 5.6 respectively.
<h3>Simultaneous equations</h3>
When S is minimum, s can be equated to 0.
On this note, it follows that the resulting equations are;
From Substitution of M = 2 +N in the second equation; it follows that;
Hence, upon solving the quadratic equation;
Therefore, the positive value of N is; 5.6 and hence,
