Answer:
38
Step-by-step explanation:
Given that,
x = -4
f(x)=x² - 4x +6
so,
f(-4)= (-4)² - 4 . (-4) +6
=16 +16 +6
= 38
Equations are expressions with equal values
- (1/3) ² +1 and 2 - 8/9 form an equation when joined together with an equals sign
- (1+ 1/5)^2 and 2 16/25 do not form an equation when joined together with an equals sign
<u>(a) (1/3) ² +1 and 2 - 8/9</u>
Rewrite as:
Evaluate the exponent
Take LCM
Simplify
Hence, (1/3) ² +1 and 2 - 8/9 form an equation when joined together with an equals sign
<u>(b) (1+ 1/5)^2 and 2 16/25</u>
Rewrite as:
Take LCM
Rewrite as:
Hence, (1+ 1/5)^2 and 2 16/25 do not form an equation when joined together with an equals sign

Answer: The value of P(A or B) is 0.8.</h3>
Step-by-step explanation: We are given P(A)=0.6 , P(B)=0.3 and P(A and B)=0.1.
P(A and B)=0.1 could be written as P(A∩B) = 0.1.
We need to find P(A or B) that is P(A∪B) = ?
We know formula,
P(A∪B) = P(A) + P(B) - P(A∩B)
Plugging values in formula, we get
P(A∪B) = 0.6 + 0.3 - 0.1
P(A∪B) = 0.9 -0.1
P(A∪B) = 0.8.
<h3>Therefore, the value of P(A or B) is 0.8.</h3>
