77.11110 it’s the nearest hundred- thousandth
The answer would be x/4<=5
The absolute value of negative 6 is 2
Answer:
![A= \frac{400}{21} B=\frac{580}{21}](https://tex.z-dn.net/?f=A%3D%20%5Cfrac%7B400%7D%7B21%7D%20B%3D%5Cfrac%7B580%7D%7B21%7D)
Step-by-step explanation:
You just have to remember the rules of the triangles in order to be able to solve this:
The rule of trigonometry that you will have to use is a is similie to 20, B is simile to 29 and 20 is 20.
So you would have to put them like this:
![\frac{21}{20}= \frac{20}{a}= \frac{29}{b}](https://tex.z-dn.net/?f=%5Cfrac%7B21%7D%7B20%7D%3D%20%5Cfrac%7B20%7D%7Ba%7D%3D%20%5Cfrac%7B29%7D%7Bb%7D)
You just have to clear the equations for A and B:
![a=\frac{20*20}{21}=\frac{400}{21}\\ b=\frac{29*20}{21} =\frac{580}{21}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B20%2A20%7D%7B21%7D%3D%5Cfrac%7B400%7D%7B21%7D%5C%5C%20%20b%3D%5Cfrac%7B29%2A20%7D%7B21%7D%20%3D%5Cfrac%7B580%7D%7B21%7D)
So that would be your answer.
The percentage of people that should be seen by the doctor between 13 and 17 minutes for this to be considered a normal distribution is; 100%.
<h3>Normal distribution</h3>
According to the question;
- Wait times at a doctor's office are typically 15 minutes, with standard deviation of 2 minutes.
In essence, the wait time can be written as;
- Wait time = 15 ± 2 minutes.
Otherwise written as;
- 13 minutes <= wait time <= 15 minutes
Ultimately, all (100%) of people should be seen by the doctor between 13 and 17 minutes.
