The left hand side of the equation is a difference of two squares and may be factored out as follows,
(x - 4)(x + 4) > 0
They may be individually taken as,
x - 4 > 0 ; x > 4
x + 4 > 0 ; x < -4
Thus, the answer to this item is letter A.
F (x)= x+12 is the inverse of the function
Answer:
Step-by-step explanation:
The given relation is
To make 
the subject, we square both sides of the equation to get;
Isolate on one side of the equation;
Or
We take the positive square root of both sides to get;
So to start off here is the question being asked:
<span>81+<span>7x</span></span>=<span>81
</span>The first thing we are going to do is s<span>implify both sides of the equation:
</span><span><span>7x</span>+81</span>=<span>81
</span>Second thing to do is s<span>ubtract 81 from both sides so:
</span><span><span><span>7x</span>+81</span>−81</span>=<span>81−<span>81
</span></span>The final thing to do is d<span>ivide both sides by 7:
</span><span><span>7x/</span>7</span>=<span>0/<span>7
The final answer is:
x=0
I hope this helps! :)</span></span>
Answer:
For this to be a binomial experiment, the assumption that is made is:
C. The probability of being selected is the same for all ten gamers.
Step-by-step explanation:
a) A binomial experiment must meet the following four conditions:
1. The experiment must consist of 'n' identical trials.
2. Each experiment must result in one of the two outcomes of either success or failure.
3. The probability of success (p) must remain the same from one experiment to the next.
