Using the Empirical Rule, it is found that:
- a) Approximately 99.7% of the amounts are between $35.26 and $51.88.
- b) Approximately 95% of the amounts are between $38.03 and $49.11.
- c) Approximately 68% of the amounts fall between $40.73 and $46.27.
------------
The Empirical Rule states that, in a <em>bell-shaped </em>distribution:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
-----------
Item a:
Within <em>3 standard deviations of the mean</em>, thus, approximately 99.7%.
-----------
Item b:
Within 2<em> standard deviations of the mean</em>, thus, approximately 95%.
-----------
Item c:
- 68% is within 1 standard deviation of the mean, so:
Approximately 68% of the amounts fall between $40.73 and $46.27.

<span>So we want to know the number from which we take 25% and get 80. If the number we are looking for is x, then the equation to find that x would be: (25/100)*x=80 which says twenty five percent out of x is equal 80. So, x=(80*100)/25. And finally, x= 8000/25=320. So, 25% out of 320 is 80.</span>
Hi there!
f(x) = -x + 2
Find f(-6) by substituting -6 for x:
f(-6) = -(-6) + 2
Simplify:
f(-6) = 6 + 2
f(-6) = 8
multiply the two numbers together, then take the square root
3* 147
441
sqrt(441)
21
The geometric mean is 21
Answer: (2,4)
Step-by-step explanation:
Vertex
|0-2| = 0
|-2| = 0
The graph is shifted 4 units up so therefore (2,4) is the vertex
