![\huge \boxed{\mathrm{A}}](https://tex.z-dn.net/?f=%5Chuge%20%5Cboxed%7B%5Cmathrm%7BA%7D%7D)
Step-by-step explanation:
The domain of a function is all possible values for the value of x.
The denominator in a rational function cannot equal to 0.
![x+2\neq 0](https://tex.z-dn.net/?f=x%2B2%5Cneq%200)
Subtracting 2 from both sides.
![x\neq -2](https://tex.z-dn.net/?f=x%5Cneq%20-2)
The domain of the function is all real numbers except -2.
Answer:
the answer is to add up all the numbers.

Answer:
61,239,550
Step-by-step explanation:
We let the random variable X denote the IQ scores. This would imply that X is normal with a mean of 100 and standard deviation of 17. We proceed to determine the probability that an individual chosen at random from the population would be a genius, that is;
Pr( X>140)
The next step is to evaluate the z-score associated with the IQ score of 140 by standardizing the random variable X;
![Pr(X>140)=Pr(Z>\frac{140-100}{17})=Pr(Z>2.3529)](https://tex.z-dn.net/?f=Pr%28X%3E140%29%3DPr%28Z%3E%5Cfrac%7B140-100%7D%7B17%7D%29%3DPr%28Z%3E2.3529%29)
The area to the right of 2.3529 will be the required probability. This area from the standard normal tables is 0.009314
From a population of 6,575,000,000 the number of geniuses would be;
6,575,000,000*0.009314 = 61,239,550

Answer:
x = -6
-18+4y=0 => 4y=18 =>y=18/4=9/2
Y=5
3x+20=0 => x=3x= -20=> x= -20/3
