Answer:
10 square meters will have a standard deviation of 1.897.
Step-by-step explanation:
Standard deviation for n instances of a variable:
If the standard deviation for one instance of a variable is
, for n instances of the variable, the standard deviation will be of 
The standard deviation of the number of flaws per square yard is 0.6
This means that 
For the 10 square yards will a standard deviation of
, so:

10 square meters will have a standard deviation of 1.897.
Answer:
9 is the real part and 7i is the imaginary part
Step-by-step explanation:
A complex number is written in the form a+bi where a is the real part and bi is the imaginary part
9 = real part
7i is the imaginary part

The diagonals of a kite are perpendicular to each other, hence
∠EHF = 90°
The sum of the 3 angles in a triangle = 180°
In ΔEHF
∠1 + ∠2 + 90 = 180, that is
42 + ∠2 + 90 = 180
132 + ∠2 = 180 ( subtract 132 from both sides )
∠2 = 48°
26
DE and DG are congruent sides, hence
4x - 2 = 22.5 ( add 2 to both sides )
4x = 24.5 ( divide both sides by 4 )
x = 6.125
27
∠A and ∠C are congruent, hence
∠A = ∠C = 82°
The sum of the interior angles of a kite = 360°, hence
x = 360 - (82 + 82 + 140) = 360 - 304 = 56
