We did not find results for: A measure of​ malnutrition, called the​ pelidisi, varies directly as the cube root of a​ person's w

eight in grams and inversely as the​ person's sitting height in centimeters. A person with a pelidisi below 100 is considered to be​ undernourished, while a pelidisi greater than 100 indicates overfeeding. A person who weighs​ 48,820 g with a sitting height of 78.7 cm has a pelidisi of 100. Find the pelidisi​ (to the nearest whole​ number) of a person whose weight is 54,688 g and whose sitting height is 72.6 cm. Is this individual undernourished or​ overfed?The pelidsi is _____Round to the nearest integer as needed..

\bf \qquad \qquad \textit{double proportional variation}\\\\

\textit{\underline{y} varies directly with \underline{x}}\\
\textit{and inversely with \underline{z}}

%pelidisi, varies directly as the cube root of a​ person's weight in grams and inversely as the​ person's sitting height in centimeters.
\textit{pelidisi varies directly}\\
\textit{as cube root of weight}\\
\textit{and inversely to }\\
\textit{sitting height}
\end{array}\implies p=\cfrac{k\sqrt[3]{w}}{s}\\\\
-------------------------------

\bf \textit{we know that }
\begin{cases}
w=48,820\\
s=78.7\\
p=100
\end{cases}\implies 100=\cfrac{k\sqrt[3]{48820}}{78.7}
\\\\\\
100\cdot 78.7=k\sqrt[3]{48820}\implies \cfrac{7870}{\sqrt[3]{48820}}=k
\\\\\\
thus\qquad \boxed{p=\cfrac{\frac{7870}{\sqrt[3]{48820}}\sqrt[3]{w}}{s}}
\\\\\\
\textit{now, what is \underline{p} when }
\begin{cases}
w=54,688\\
s=72.6
\end{cases}?\implies p=\cfrac{\frac{7870}{\sqrt[3]{48820}}\sqrt[3]{54688}}{72.6}

now, if that value is less than 100, then the fellow is "undernourished", otherwise, is overfed.

Find the area of the shaded region. The graph to the right depicts IQ scores of adults, and those scores are normally distribute
bulgar [2K]

Answer:

The area of the shaded region is 0.2898.

Step-by-step explanation:

Let <em>X</em> represent the IQ scores of adults.

It is provided that X\sim N(100,15^{2}).

Compute the probability of an adult having an IQ between 106 and 124 as follows:

P(106

                             =P(0.40

*Use a <em>z</em>-table.

Thus, the area of the shaded region is 0.2898.
