Step-by-step explanation:
Answer:
40 km^2
16 cm^2
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
Actual area = scale factor x scaled area
8 x 5 = 40 km^2
Scaled area on the map = 128.8 = 16 cm^2
Divide both sides by 
:
If 
, then
and more generally, for any integer 
,
Answer:
Step-by-step explanation:
Solve for the mean (average) of the five test scores.
Subtract that mean from each of the five original test scores. Square each of the differences.
Find the mean (average) of each of these differences you found in Step 2.
Take the square root of this final mean from #3. This is the standard deviation.
