Answer:
B
Step-by-step explanation:
Given
P = 2(l + b) ← distribute
P = 2l + 2b ( subtract 2b from both sides )
P - 2b = 2l ( divide both sides by 2 )
= l → B
The answer to the question is lean
The mean of the dataset is the average, while the median is the middle element.
- <em>The mean and the median of the given dataset is 98.2</em>
- <em>The results support the common belief that the mean body temperature is 98.6F</em>
<em />
The mean of the dataset is calculated using:
![\bar x = \frac{\sum x}{n}](https://tex.z-dn.net/?f=%5Cbar%20x%20%3D%20%5Cfrac%7B%5Csum%20x%7D%7Bn%7D)
So, we have:
![\bar x = \frac{99.2+ 99.2 +98.2+............+97.7}{48}](https://tex.z-dn.net/?f=%5Cbar%20x%20%3D%20%5Cfrac%7B99.2%2B%2099.2%20%2B98.2%2B............%2B97.7%7D%7B48%7D)
![\bar x = \frac{4715}{48}](https://tex.z-dn.net/?f=%5Cbar%20x%20%3D%20%5Cfrac%7B4715%7D%7B48%7D)
![\bar x = 98.2](https://tex.z-dn.net/?f=%5Cbar%20x%20%3D%2098.2)
The median position is:
![Median = \frac{1}{2}(n + 1)](https://tex.z-dn.net/?f=Median%20%3D%20%5Cfrac%7B1%7D%7B2%7D%28n%20%2B%201%29)
![Median = \frac{1}{2}(48 + 1)](https://tex.z-dn.net/?f=Median%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2848%20%2B%201%29)
![Median = \frac{1}{2}(49)](https://tex.z-dn.net/?f=Median%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2849%29)
![Median = 24.5](https://tex.z-dn.net/?f=Median%20%3D%2024.5)
This means that the median is the average of the 24th and 25th element
Using the sorted dataset, we have:
![Median = \frac{1}{2}(98.2 + 98.2)](https://tex.z-dn.net/?f=Median%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2898.2%20%2B%2098.2%29)
![Median = 98.2](https://tex.z-dn.net/?f=Median%20%3D%2098.2)
<em>Because the calculated mean and the common belief (98.6) are close, then we can conclude that the results support the common belief that the mean body temperature is 98.6F</em>

Answer: x - int : (3,0)
Step-by-step explanation:
point-slope form: y - y1 = m(x - x1)
m = y2-y1/x2-x1
= -4-2/-3-6
=-6/-9
= 2/3
y1 = 2
x1 =6
y - 2 = 2/3(x-6)
x -int: when y = 0, what is x?
0-2 = 2/3(x-6)
-2 = 2/3x - 4
2 = 2/3x
x=3
~Hope this helps!~
