4^4 * 4^(-9) = 4^(4-9) = 4^(-5) or 1/(4^5)
X would equal 81 because the square root of 81 is 9.
9 x 9 = 81
Answer:
Angle 1 is 48°
Step-by-step explanation:
So angle 1 + angle 2 + angle 3 = 180°
Angle 2 = 90°
Angle 3 = 42°
180 - 90 - 42 = 48°
Answer:
Simplifying the expression:
we get 
Step-by-step explanation:
We need to simplify the expression: 
First we will solve terms inside the bracket

Converting mixed fraction
into improper fraction, we get: 
Replacing the term:

Now, taking LCM of: 5,3,4,2 we get 60
Now multiply 60 with each term inside the bracket

Now, combine like terms

Now, multiply all terms with 2

So, Simplifying the expression:
we get 
Answer:
7/80
Step-by-step explanation:
Given that: P(B) = 7 / 20, P(A|B)= 1 / 4
Bayes theorem is used to mathematically represent the conditional probability of an event A given B. According to Bayes theorem:

Where P(B) is the probability of event B occurring, P(A ∩ B) is the probability of event A and event B occurring and P(A|B) is the probability of event A occurring given event B.
