Answer:
Step-by-step explanation:
Given that there are 12 people sitting around at a table.
We see that any two persons can have conversations. If we count A with B as one conversation this is the same as B with A
i.e. order does not matter
So here we have to use combinations.
2 people out of 12 where order does not matter can be done in 12C2 ways
No of conversations =
If we use a dodedecon as a geometrical figure with 12 vertices representing 12 persons the conversation between pairs can be associated with all diagonals and sides connecting two vertices.
Sides are 12 and diagonals are 54 totalling 66.
Answer:
2n-7
Step-by-step explanation:
the product of 2 and a number is 2 times a number, so number is n. (this is multiplicaiton) it then becomes 2n. 7 less than that is 2n-7. (If it's less than, it goes after the variables 2n)
Explanation:
7 less --> -7
product of 2 and a number --> 2x
Answer:
2x-7
I hope this Helps!!
b.p ∧ q
c. p → q
c.q → p
d. q ↔ p
A statement is true if both p and q will be true.
As, given ,p: A triangle is acute
q: A triangle is equilateral.
p ∧ q→ p is true as well as q is true.
That is if triangle is acute it means it is equilateral is not possible, and if triangle is equilateral it means it is acute angled triangle.So,this contradicts p∧q.
So, Option (c) q → p, supports the two statement , that is if if triangle is equilateral it means it is acute angled triangle.
