The members of a possible set C are {6, 9, 12}
<h3>Set theory</h3>
The universal set is the set that contains all other sets. Given the following sets
ξ = {x:x is an integer, 2 ≤ x ≤ 14}
B = {x:x is a prime number}
A = {x:x is a multiple of 3}
The sets B and A are:
B = {2, 3, 5, 7, 11}
A = {3, 6, 9, 12}
If C is a subset of A with a cardinality of 3, hence the required set will be {6, 9, 12}. Note that 3 is excluded since B n C must be an empty set.

I’ll do an example problem, and I challenge you to do this on your own!
If the example is find the difference between 0645 and 1200, we know that there are 60 minutes in an hour, so 0645 is 6 hours and 45 minutes or 6+45/60=6+3/4 of an hour by dividing both the numerator and denominator by 15. Finding that in minutes, we have 60*6+45=360+45=395 minutes due to that you add 60 minutes for every hour.
1200 is just noon, but that’s 12 hours, so we can convert that into minutes - 60*12=720
Finding the difference, we get
720
-395
_____ due to that -395=-400+5, so 720-400=320 and 320+5=325
325
Converting them back into hours, we get 325/60=5+25/60, which is 5 60 minute increments (5 hours) and 25 minutes, or 0525
Good luck, and feel free to ask any further questions!
Answer:
Since there are 16 pastries in total, and 7 of them are chocolate, this will become your probability.
So, since the total is 16, this will be the denominator, and the 7 will be the numerator.
So, it will be
Answer:
3d
Step-by-step explanation:
A regular hexagon has six equivalent triangles, each triangle having one side of that of the hexagon. if the diameter of the circle in which the hexagon is inscribed is d , then its radius will be
this radius also happens to be one of the side of the equivalent triangle whose one side is also the side of hexagon. since length of one side of hexagon is
the circumference of the hexagon will be
Answer:
96 sq. m
Step-by-step explanation:
If the width is x, the length is x + 4 and since perimeter = 2 * (length + width), we can write:
40 = 2(x + x + 4)
40 = 2(2x + 4)
20 = 2x + 4
16 = 2x
x = 8 so x + 4 = 12, therefore the area is 8 * 12 = 96 square meters.
