the intensity, I, of light varies inversely as the square of the distance, D2 , from the light source. If I is 150 units when D

podryga [215]

$\bf \textit{\underline{x} varies inversely with }\underline{z^5} ~\hspace{5.5em} \stackrel{\textit{constant of variation}}{x=\cfrac{\stackrel{\downarrow }{k}}{z^5}~\hfill } \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \stackrel{\textit{\underline{I} varies inversely with }\underline{D^2}}{I = \cfrac{k}{D^2}} \qquad \qquad \textit{we also know that } \begin{cases} I=150\\ D=6 \end{cases}$

$\bf 150=\cfrac{k}{6^2}\implies 150=\cfrac{k}{36}\implies 5400=k~\hfill \boxed{I=\cfrac{5400}{D^2}} \\\\\\ \textit{when I = 24, what is \underline{D}?}\qquad \qquad 24=\cfrac{5400}{D^2}\implies D^2=\cfrac{5400}{24} \\\\\\ D^2=225\implies D=\sqrt{225}\implies D=15$

A manufacturer makes bags of popcorn and bags of potato chips. The average weight of a bag of popcorn is supposed to be 3.06 oun

alexandr1967 [171]

Answer:

The potato bag assembly line is closer to the specifications given because its z-score is closer to the standard mean than the popcorn chip bag assembly line.

Step-by-step explanation:

Popcorn mean= μ`1= 3.06

Popcorn St. Dev= σ1= 0.02

Potato Mean= μ`2= 5.05

Potato St. Dev= σ2= 0.05

Finding the z score

z= x- u / σ

Popcorn z= 3.06- 3.03/0.02= 1.5

Potato Z= 5.05-5.07/0.05= -0.4

The mean is taken to be at zero ( 0) therefore difference of 0.4 is less than a difference of 1.5

Choice 3 is the best option .
