The in-situ dry density of a sand is 1.72Mg/m3. The maximum and minimum drydensities, determined by standard laboratory tests, are 1.81 and 1.54 Mg/m3,respectively. Determine the relative density of the sand and soil description based on its density.
Answer:
Relative density = 0.7 or 70%
Explanation:
The following information was provided by this question
Pd = 1.72mg/mg³
Pd max = 1.81 mg/mg³
Pd min = 1.54 mg/mg³
We substitute into the formula. This formula is contained in the attachment.
[(1/1.54)-(1/1.72)]/[1/1.54 - 1/1.81]
= 0.649350 - 0.581395 / 0.649350 - 0.552486
= 0.067955/0.096864
= 0.7015
= 0.7
The relative density is Therefore 0.7 or 70% when converted to percentage
Which statement about the seal between the respirator and the wearer's face is true?
POSSIBLE ANSWERS:
Negative pressure respirators prevent ambient air from entering the mask.
Cosmetic surgery can be completed without a re-evaluation of respirator fit.
Positive pressure respirators tighten the face mask when the wearer inhales.
Facial hair can prevent a respirator from properly sealing to the wearer’s face.
A true statement about the seal between the respirator and the wearer's face is: D. facial hair can prevent a respirator from properly sealing to the wearer’s face.
What is a respirator?A respirator can be defined as a personal protective equipment that is typically worn over the face to protect the mouth and nose, while protecting the wearer from inhaling smoke, dust, or other toxic chemical substances.
In this context, a true statement about the seal between the respirator and the wearer's face is that facial hair has the ability to prevent a respirator from properly sealing to the wearer’s face.

In manufacturing a particular set of motor shafts, only shaft diameters of between 38.20 and 37.50 mm are usable. If the process mean is found to be 37.80 mm with a standard deviation of 0.20 mm, what percentage of the population of manufactured shafts are usable?
Answer:
we can conclude that 91.04% population of shafts are usable
Explanation:
Given that;
X[tex]_{min}[/tex] = 37.50 mm
X[tex]_{max}[/tex] = 38.20 mm
mean μ = 37.80
standard deviation σ = 0.20 mm
This problem is based on normal probability distribution so, to get the probability, we must calculate; z = x-μ / σ
so;
Z[tex]_{min}[/tex] = (X[tex]_{min}[/tex] - μ) / μ = (37.50 - 37.80) / 0.20 = -1.5
Z[tex]_{max}[/tex] = (X[tex]_{max}[/tex] - μ) / μ = (38.20 - 37.80) / 0.20 = 2
Hence;
P( 37.50 < X < 38.20 ) = P( -1.5 < Z < 2 )
P( 37.50 < X < 38.20 ) = P( 0 < Z < 1.5 ) + P( 0 < Z < 2 )
from the standard normal table table;
P( 37.50 < X < 38.20 ) = 0.4332 + 0.4772
P( 37.50 < X < 38.20 ) = 0.9104 = 91.40%
Hence, we can conclude that 91.04% population of shafts are usable
