P(z ≤ -a) + P(-a ≤ z ≤ a) + P(z ≥ a) = 1 - P(z ≤ a) + [P(z ≤ a) - P(z ≤ -a)] + 1 - P(z ≤ a) = 2 - 2P(z ≤ a) + P(z ≤ a) - [1 - P(z ≤ a)] = 2 - P(z ≤ a) - 1 + P(z ≤ a) = 1
Therefore, option D is the correct answer.
Answer:
i have no idea
Step-by-step explanation:
In all triangles, inner angles add to 180 degrees.
In an isosceles triangle, the base angles are the same and the vertex angle is different from the rest.
b= (180-40)/2
b= 140/2
b=70
Final answer: 70 degrees
Answer:
Distributive property
Step-by-step explanation:
the factor "3" which appears outside the parenthesis multiplies the two terms inside it. You perform the multiplication term by term. It is also referred to as the factor "3" distributes among the terms inside the parenthesis, multiplying each.
