An experiment compared the adhesion of 2 types of paint, A and B, to 3 types of metal, 1, 2, and 3, used in automobiles. Thirty

sheets of metal were used in the experiment: 10 of Metal 1, 10 of Metal 2, and 10 of Metal 3. Half of each metal type will receive paint A and the other half will receive paint B. The adhesion of the paints was measured, and the measures were compared. How many experimental units are in the experiment?
A. 2

B.3


C. 10


D. 30


E. 60

Answer:

<em></em>

  • <em>There are 30 experimental units in the experiment, which are the 30: the thirty sheets of metal.</em>

Explanation:

This table shows you how the <em>experimental</em> units, <em>sheets of metal</em>, were treated:

               Metal 1         Metal 2       Metal 3       Total

Paint A         5                     5               5                15

Paint B         5                     5               5                15

Total            10                   10              10               30

Fifteen sheets (units) were treated with <em>paint A</em>: 5 of metal 1, 5 of metal 2, and 5 of metal 3.

Fifteen sheets (units) were treated with <em>paint B</em>: 5 of metal 1, 5 of metal 2, and 5 of metal 3.

Surface Area of a can is 517.8 cm^2. Maximize the volume of this can using the measured surface area.
mafiozo [28]

Answer:

r = 5.24 --- Radius

h = 10.48 --- Height

Explanation:

Given

Object: Can (Cylinder)

Surface\ Area = 517.8cm^2

Required

Maximize the volume

The surface area is:

S.A = 2\pi r^2 + 2\pi rh

Substitute 517.8 for S.A

517.8 = 2\pi r^2 + 2\pi rh

Divide through by 2

258.9 = \pi r^2 + \pi rh

Factorize:

258.9 = \pi r(r + h)

Divide through by \pi r

\frac{258.9}{\pi r} = r + h

Make h the subject

h = \frac{258.9}{\pi r} - r --- (1)

Volume (V) is calculated as:

V = \pi r^2h

Substitute (1) for h

V = \pi r^2(\frac{258.9}{\pi r} - r)

Open Bracket

V = 258.9r - \pi r^3

Differentiate V

V' = 258.9 - 3\pi r^2

Set V' to 0

0 = 258.9 - 3\pi r^2

Collect Like Terms

3\pi r^2 = 258.9

Divide through by 3

\pi r^2 = 86.3

Divide through by \pi

r^2 = \frac{86.3}{\pi}

r^2 = \frac{86.3*7}{22}

r^2 = \frac{604.1}{22}

Take square root of both sides

r = \sqrt{\frac{604.1}{22}

r = 5.24

Recall that:

h = \frac{258.9}{\pi r} - r

Substitute 5.24 for r

h = \frac{258.9}{\pi * 5.24} - 5.24

h = \frac{258.9*7}{22 * 5.24} - 5.24

h = \frac{1812.3}{115.28} - 5.24

h = 15.72 - 5.24

h = 10.48

Hence, the dimension that maximize the volume is:

r = 5.24 --- Radius

h = 10.48 --- Height

What does Wallace mean when he refers to the “natural, hard-wired default-setting”
pychu [463]
<span>All of us are a product of the culture we are raised in, the rules and regulations that we must follow and the spoken and unspoken world views that are passed on. We see the world from our perspective and our reality, we cannot help it, it is the filter we look at life through. Sometimes without even knowing how prejudiced we are, we form our opinions from the experiences we have had and what we have watched as we were growing up. Everything comes from a place deep within us that helps us make sense of the world and the people in it.</span>
