Answer:
The body temperature of a male at the 83rd percentile is 98.8°F.
Explanation:
The <em>n</em>th percentile implies that there are <em>n%</em> value below this percentile value.
That is, if P (<em>X </em><<em> x</em>) = n% then <em>x</em> is the <em>n</em>th percentile.
Let<em> </em><em>X</em> = male body temperature.
The random variable <em>X</em> follows a Normal distribution with mean, <em>μ</em> = 98.4°F and standard deviation, <em>σ</em> = 0.40°F.
Let <em>x</em> be the 83rd percentile value.
Then, P (X < x) = 0.83.
The value of <em>x</em> can be computed from the <em>z</em>-score.
![z=\frac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
Compute the <em>z</em>-score related to this probability as follows:
P (Z < z) = 0.83
*Use the <em>z</em>-table for the <em>z</em>-score.
The value of <em>z</em> is 0.95.
Compute the value of <em>x</em> as follows:
![z=\frac{x-\mu}{\sigma}\\0.96=\frac{x-98.4}{0.40} \\x=98.4+(0.96\times0.40)\\=98.784\\\approx98.8](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D%5C%5C0.96%3D%5Cfrac%7Bx-98.4%7D%7B0.40%7D%20%5C%5Cx%3D98.4%2B%280.96%5Ctimes0.40%29%5C%5C%3D98.784%5C%5C%5Capprox98.8)
Thus, the body temperature of a male at the 83rd percentile is 98.8°F.

The correct answer is: Area of △ABC = 20Explanation:Since the area of △AOD = 10; therefore. the area of <span>△BOC is also 10.
Now:
The area of </span>△ABC = Area of △AOB + Area of <span>△BOC --- (1)
Since Area of </span>△AOB =
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
(Area of <span>△ABC) --- (2)
Plug (2) in (1):
(1) => Area of </span>△ABC =
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
(Area of △ABC) + 10
=>
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
(Area of △ABC) = 10
=> (Area of △ABC) =

Assuming he sold all the shares of both companies for $600 and $900 respectively. what the ratio of return on investment from company x to that from company y will be is : 2:3
First step is to calculate x return on investment
x return on investment = $600 - $500
x return on investment= $100
Second step is to calculate y return on investment
y return on investment= $900 - $750
y return on investment= $150
Now let determine the ratio of return on investment from company x to that from company y
Using this formula
Ratio of return on investment=x return on investment/y return on investment
Let plug in the formula
Ratio of return on investment=100/150
Ratio of return on investment=2/3
Ratio of return on investment=2:3
Inconclusion assuming he sold all the shares of both companies for $600 and $900 respectively. what the ratio of return on investment from company x to that from company y will be is : 2:3
