Final answer is
.
Step-by-step explanation:
Given that P(A)= .50, P(B)=.80 , and P(A and B)=.20.
Now we need to find about what is the value of P(B/A).
So apply the formula of compound probability :
P(A and B) = P(A)*P(B/A)
Plug the given values into above formula
0.20 = 0.50*P(B/A)
0.50*P(B/A) = 0.20


Hence final answer is
.
Answer:
Step-by-step explanation:
This is asking what is A
Formula A squared + B squared = C squared
A=x
B=8
C=20
X^2+ 8^2=20^2
8 squared is 64
20 squared is 400
400-64 is 336
X*X=336 find the square root of 336 =18.3
CHECK
18.3*18.3+ 8*8=398.89 which is super close to 400
Rewrite then factor as a difference of cubes:
1 - 64<em>x</em>³ = 1³ - (4<em>x</em>)³
= (1 - 4<em>x</em>) (1² + 4<em>x</em> + (4<em>x</em>)²)
= (1 - 4<em>x</em>) (1 + 4<em>x</em> + 16<em>x</em>²)
