Answer: 0.00102%
Step-by-step explanation:
Given : Human body temperatures are normally distributed with a mean of
and a standard deviation of ![s=0.61^{\circ}F](https://tex.z-dn.net/?f=s%3D0.61%5E%7B%5Ccirc%7DF)
A hospital uses
as the lowest temperature considered to be a fever.
Let x be the random variable that represents the human body temperatures.
![z=\dfrac{x-\mu}{s}](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7Bx-%5Cmu%7D%7Bs%7D)
For x= 100.6, ![z=\dfrac{100.6-98}{0.61}=4.26229508197\approx4.26](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B100.6-98%7D%7B0.61%7D%3D4.26229508197%5Capprox4.26)
Using normal distribution table for z-values for right-tailed area ,
P(x>100.6)=![P(Z>4.26)=0.0000102=0.00102\%](https://tex.z-dn.net/?f=P%28Z%3E4.26%29%3D0.0000102%3D0.00102%5C%25)
Hence, the required probability = 0.00102%

Step-by-step explanation:
Area of rectangle = 2(2w - 5) is the factored form of given expression
Multiplying the length and width of a rectangle, we get the area of the rectangle
<em><u>Solution:</u></em>
Given that, area of rectangle is 4w - 10 square units
We have to factor the expression
From given,
Area of rectangle = 4w - 10
Take 2 as common factor
Area of rectangle = 2(2w - 5)
Thus the given expression is factored
<em><u>The area of rectangle is given as:</u></em>
![Area\ of\ rectangle = length \times width](https://tex.z-dn.net/?f=Area%5C%20of%5C%20rectangle%20%3D%20length%20%5Ctimes%20width)
![Area\ of\ rectangle = 2 \times (2w - 5)](https://tex.z-dn.net/?f=Area%5C%20of%5C%20rectangle%20%3D%202%20%5Ctimes%20%282w%20-%205%29)
Thus, multiplying the length and width of a rectangle, we get the area of the rectangle
When we multiply 2 with 2w - 5 we get the area of rectangle
From above we can say,
Length = 2 or 2w - 5
Width = 2w - 5 or 2
So when dimensions of rectangle are multiplied we get area of rectangle
