Answer:
The probability of randomly selecting someone who does not believe that statistics teachers know the true meaning of life is 0.426.
Step-by-step explanation:
Let <em>X</em> = number of Americans who believe that statistics teachers know the true meaning of life.
The probability of the random variable <em>X</em> is,
P (X) = 0.574
The event of a person not believing that statistics teachers know the true meaning of life is the complement of the event <em>X</em>.
The probability of the complement of an event, <em>E</em> is the probability of that event not happening.
Compute the value of as follows:
Thus, the probability of randomly selecting someone who does not believe that statistics teachers know the true meaning of life is 0.426.
The value of (fg)(x)= 3x³+ x²
<h3>What is function?</h3>An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given:
f(x) = -3x+1
g(x) =
Now, (fg)(x)
=f(x) * g(x)
= (-3x+1) * ()
=-3x³+ x²
Hence, (fg)(x)= 3x³+ x²
