-2/3x -11=-7
-2/3x = 11 - 7
-2/3x = 4
x = 4 : (-2/3)
x = 4 * (-3/2)
x = 4 *(-3) : 2
x = -12 : 2
x = -6
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.
Given the position function, the velocity function is obtained by taking the derivative:

The velocity is increasing its own derivative is positive, so we also have to find the acceleration by taking another derivative:

To find when
, we first need to know where
:

The quadratic factor is always positive (its discriminant is negative), which leaves one solution at
. To either side of
, we have, for instance,


which indicates that
is increasing for
, making the answer A.
