Flipping a coin is an independent event, meaning the probability of getting heads or tails does not depend on the previous flip. It's 1/2 or 0.5 chance every time.
So three coin flips would be = (0.5)*(0.5)*(0.5)
= 0.125
× 100%
= 12.5% chance
Answer:
C = 72
Step-by-step explanation:
Answer:
1/9
Step-by-step explanation:
If x is the given number, the reciprocal is 1/(0-x)
Differences between x-values are 1. Differences between y-values are 2. The y-values are changing 2 times as fast as the x-values, so you are looking for an answer that involves 2x. The appropriate choice is
D. 2x + 3
_____
You can check this result:
for x=1: 2·1 + 3 = 5
for x=4: 2·4 + 3 = 11
These values correspond to those in the table.
Answer:
Correct answer: A₁ : A = 1 : 9
Step-by-step explanation:
Given: a = 3 a₁
Side of the first triangle let be a and of the second a₁
Area of the first triangle let be A and of the second A₁
If the two triangles are similar then it is:
A₁ : A = a₁² : a²
A₁ : A = a₁² : (3 a₁)² = a₁² : 9 a₁² = 1 : 9
A₁ : A = 1 : 9
