You divide 1/4 by 1/16

KCF- 1/4 x 16/1 = 16/4 = 4

You need 4 runners total, I hope I helped

zhenek [66]

Answer:

The intensity on a screen 70 ft from the light is 1.728 foot candle.

Step-by-step explanation:

Given that,

The magnitude of intensity $I$ of light varies inversely as the square of the magnitude of distance D from the source.

That is

$I\propto \frac{1}{D^2}$

Then,

$\frac{I_1}{I_2}=\frac{D_2^2}{D_1^2}$

Given that,

The magnitude of intensity of illumination on a screen 56 ft from a light is 2.7 foot-candle.

Here,

$I_1$ =2.7 foot-candle, $D_1$ = 56 ft

$I_2$ =?, $D_2$ = 70 ft.

$\frac{I_1}{I_2}=\frac{D_2^2}{D_1^2}$

$\Rightarrow \frac{2.7}{I_2}=\frac{70^2}{56^2}$

$\Rightarrow \frac{I_2}{2.7}=\frac{56^2}{70^2}$

$\Rightarrow {I_2}=\frac{56^2\times 2.7}{70^2}$

$\Rightarrow {I_2}=1.728$ foot-candle

The intensity on a screen 70 ft from the light is 1.728 foot candle.

A graduate student in social work survey students at 10 colleges in a mid western state to find how many are single parents the results are the data below.

471, 134, 316, 514, 810, 183, 419, 859, 246, 676

Required:

Find the mode. If there is more than one answer separate them with commas select non-if applicable.

Explanation:

The mode is the number in a data set that occurs most frequently. Count how many times each number occurs in the data set. The mode is the number with the highest tally. It's ok if there is more than one mode.

So, mode =

Answer:

Hence, mode = None
