<span>You are paid $78 for 61/2 hours of work.
Question: What is your rate of pay?
=> 78 dollars = is the money paid to you
=> 6 and ½ is the time you rendered for work
=> 6 and half hours = 6.50 hours or 6 hours and 30 minutes
Solution:
=> 78 dollars / 6.5 hours = 12 dollars.
Thus, your rate is 12 dollars per hour (12 dollars/h)</span>

A swimming pool is 20 ft wide, 40 ft long, 3 ft deep at the shallow end, and 9 feet deep at its deepest point. If the pool is be

Using implicit differentiation, it is found that the water level is rising a rate of 0.001 ft/sec.

The volume of a pool of <u>length l, width w and height h</u> is given by:

$V = lwh$

Applying <em>implicit differentiation</em>, the rate of change of the volume is given by:

$\frac{dV}{dt} = wh\frac{dl}{dt} + lh\frac{dw}{dt} + lw\frac{dh}{dt}$

<u>Neither the width nor the length changes</u>, hence $\frac{dl}{dt} = \frac{dw}{dt} = 0$ , and:

$\frac{dV}{dt} = lw\frac{dh}{dt}$

We are given that:

$\frac{dV}{dt} = 0.3, l = 20, w = 40$ , hence:

$\frac{dV}{dt} = lw\frac{dh}{dt}$

$0.8 = 20(40)\frac{dh}{dt}$

$\frac{dh}{dt} = \frac{0.8}{800}$

$\frac{dh}{dt} = 0.001
$

Water level is rising at rate of 0.001 ft/sec.

Which of the following is true of histograms? (Check all that apply.)

Leviafan [203]

1:

A - actually not true, a probability plot would be better

B - not true, since exact values are plotted a box-and-whisker would be better

C - true (that's what a histogram does)

D - True (You can get the measures of central tendency quickly)

2:

A - true

B - False - those are easily found

C - False - They are arranged on the x-axis

D - True - see above
