Answer:
The mean is defining the average length(2.5in) of the 100 measured screws.
Step-by-step explanation:
The mean is usually calculated in order to determine the average of a set of values.
To apply a scale to a measure, you have to follow this rule:
Real measure x Scale = Scaled measure
So the drawings will have:
4 x 1/24 = 0'167 feet
6 x 1/24 = 0'25 feet
<span>Windows: 0'167 by 0'25 feet
</span>
<span>12 x 1/24 = 0'50 feet
</span><span>8 x 1/24 = 0'33 feet
</span>Doors: 0'33 by <span>0'50 feet</span>
Answer:
1376 minutes
