Part A:
The total area = x² + 12x + 20 = (x+2)(x+10)
<span>The width = x+2
∴ Length = area / width = </span>[ <span>(x+2)(x+10) ] / (x+2) = x+10
Part B: </span>
<span>A 2-foot walkway is built around the fountain
</span>
<span>∴ The width = (x+2) + 2 + 2 = x + 6
The length = (x+10) + 2 + 2 = x +14
Part C:
</span><span>the total area covered by the fountain and walkway. </span><span>
= (x+6)(x+14)
= x² + 20 x + 84

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.
