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;

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
Using the given table:
a) the average rate of change is 32.5 jobs/year.
b) the average rate of change is 12.5 jobs/year.
<h3>
How to find the average rate of change?</h3>
For a function f(x), the average rate of change on an interval [a, b] is:

a) The average rate of change between 1997 and 1999 is:

So the average rate of change is 32.5 jobs/year.
b) Now the interval is 1999 to 2001.
The rate this time is:

So the average rate of change is 12.5 jobs/year.

Answer:
110%
Step-by-step explanation:
just divide by 2
20/2 = 10
22/2 = 11
so x% of 10 = 11
1.10 just like the last problem
110%
Answer:
This type of transformation is a horizontal stretch.
<em></em>
Step-by-step explanation:
Given


Required
Determine the type of transformation
The first function can be expressed as:

While the second function is:

Solving f(0.5x), we have to substitute 0.5x for x in 

So:
The second function is:

<em>This type of transformation is a horizontal stretch.</em>
<em></em>
<em>i.e. f(x) stretched to g(x)</em>
