The perimeter is 6x + 12, and a model example is attached.
All three sides of an equilateral triangle are the same, so multiply the side length by 3 to find the perimeter.
3(2x + 4)
Now distribute the 3.
3 * 2x + 3 * 4
6x + 12
Answer:
390625
Step-by-step explanation:
To find something to the power of something you will multiply it by itself as many times as it is stated.
For example 2 to the power of 2 would be 4!( 2 x 2=4)
So 25 to the power of 5 would be set up as follows
25 x 25 x 25 x 25 x 25
625 x 625 x 25
625 x 15625=390625
Answer:
B.) P(A/B) = P(A)
Step-by-step explanation:
If two events, A and B are independent:
We have that:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
Since they are independent:
Then
So
, or either:
, and thus, the correct answer is given by option B.
