Answer:

In statistics, quality assurance, and survey methodology, sampling is the selection of a subset of individuals from within a statistical population to estimate characteristics of the whole population. Statisticians attempt for the samples to represent the population in question.

A 4cm by 6cm rectangle sits inside a circle with a radius of 11 cm what is the shaded region
mafiozo [28]

Answer:

355.94 cm2

Step-by-step explanation:

if it is the area of the shaded part, you have to find the area of rectangle and the area of the circle, then subtract the rectangle's area from the circle's.

area of circle = 3.14( i used this π because the radius is not divisible by 7) × 11 × 11 = 379.94.

area of rectangle = 6 × 4 = 24cm

379.94 - 24.00 = 355.94cm2.

5) So for parallelogram ABCD, ∠B ≅ ∠D, and ∠A ≅ ∠C. Further, ∠B and ∠A are supplementary (i.e., their sum is 180°), and ∠D and ∠C are also supplementary.

So, we have that m∠B = m∠D. Therefore, 

6x-42=3x+15\\3x=57\\x=19.

Now, let's substitute for x back into the expression for either ∠B or ∠D to find it's angle measure.

m∠B = 6(19)-42=72

Now, remember that ∠B or ∠D are supplements of ∠A. 

So, m∠B + m∠A = 180°.

That means m∠A = 180° – 72° = 108°.

That seems reasonable, because A appears to be an obtuse angle.

6) 

m∠BAE + m∠DAE + m∠ABC = 180°
3x+6+10x+2+12x-3=180\\25x+5=180\\x=7

∠ABC ≅ ∠ADC.

m∠ABC = 12(7)-3=81

m∠ADC = 81°.

7)

AC=5x+1
AE=3x-3
AB=4x+1

AC=2AE\\\\5x+1=2(3x-3)\\\\5x+1=6x-6\\\\7=x

AB=DC

AB=4(7)+1=29

DC = 29
