13 you had to round 12/5 to a whole :) :) :) :)
Answer:
Yes.
Step-by-step explanation:
A quadrilateral is any polygon with four sides. A rectangle, by definition, is a polygon with four sides and four right angles. Thus, every rectangle is a quadrilateral.
Answer:
The domain of P is given by,
{n | n ∈ N, 2 ≤ n ≤ 12}
Step-by-step explanation:
A perfect die is perfectly cubic in shape with one of the integers 1,2,3,4, 5 or 6 in each of it's 6 faces and the digits on any two faces are different.
Now, two dice are rolled and P(n) models the probability of the event that the sum on the faces of the two dice is n.
Hence, the domain of P is given by,
{n | n ∈ N, 2 ≤ n ≤ 12}
Answer: x=158
Explain: 3 triangle corners = 180
180-90-68 = 22
Flat corner = 180
=> x=180-22=158
