When setting up a proportion to calculate scale drawings, how do you write the proportion? A)actual/actual B)actual/drawing C) drawing/drawing D)drawing/actual
The correct answer is option D: drawing/actual
Suppose there is a drawing that has a scale of 1:10. So, this means anything drawn with the size of "1" would have an actual size of "10" in the real world, so a measurement of 120mm on the drawing would be 1200mm on the actual/real image.

Answer:
7 1/3
Step-by-step explanation:
1 2/3 - ( -5 2/3)
Subtracting a negative is like adding
1 2/3 + 5 2/3
6 4/3
Simplify the fraction
6 3/3 + 1/3

Answer:
36
Step-by-step explanation:
Data provided in the question:
Standard error = 1.5 minutes ( ∵ number are repetitive 1.51.5 )
Standard deviation = 9 minutes ( ∵ number are repetitive 99 )
Now,
Standard error = ( Standard deviation ) ÷ √n
Here,
n is the sample size
Therefore,
on substituting the respective values, we get
1.5 = 9 ÷ √n
or
√n = 9 ÷ 1.5
or
√n = 6
or
n = 6² = 36
