Number of combinations possible = 4! / 2! 2! = 6
Each of these has probability 1/2*1/2*1/2*1/2 = 1/16
Required probability = 6 * 1/16 = 3/8
What is the median of the following data set? -5000, -4999, -4998, ..., -1, 0, 1, ..., 4998, 4999, 5000

Answer:
o
Step-by-step explanation:
the median is obvi zero
Step-by-step explanation:
To prove that 3 + 2√5 is an irrational number, we will use the contradiction method.
Let us assume that 3 + 2√5 is a rational number with p and q as co-prime integers and q ≠ 0
⇒ 3 + 2√5 = p/ q
⇒ 2√5 = p/ q - 3
⇒ √5 = (p - 3q ) / 2q
⇒ (p - 3q ) / 2 q is a rational number.
However, √5 is an irrational number
This leads to a contradiction that 3 + 2√5 is a rational number.
Answer:
Both 70 degrees
Step-by-step explanation:
The base angles of an isosceles triangle are congruent.
The other 2 angles are each (180 - 40) / 2
= 70 degrees
