Answer:

Third option is correct. The area of figure is 21.25m^2.

Step-by-step explanation:

The area of a kite is

A=\frac{1}{2}(d_1\times d_2)

Both diagonals are perpendicular. Longer diagonal bisects the smaller diagonal.

In triangle ABO,

\tan45^{\circ}=\frac{BO}{AO}

1=\frac{BO}{2.5}

2.5=BO

The length of BD is

BD=2\times BO=2\times 2.5=5

The length of AC is

6+2.5=8.5

The area of kite ABCD is

A=\frac{1}{2}(AC\times BD)

A=\frac{1}{2}(8.5\times 5)

A=21.25

Therefore third option is correct. The area of figure is 21.25m^2.

G with the definition of covariance, prove cov[(ay − b),(cy − d)] = accov(x, y ), where x, y are random variables and a, b, c, d
____ [38]

By definition of covariance,


\mathrm{Cov}(X,Y)=\mathbb E[(X-\mathbb E[X])(Y-\mathbb E[Y])]


\mathrm{Cov}(X,Y)=\mathbb E[XY-\mathbb E[X]Y-X\mathbb E[Y]+\mathbb E[X]\mathbb E[Y]]=\mathbb E[XY]-\mathbb E[X]\mathbb E[Y]


We have


\mathbb E[(aX-b)(cY-d)]=\mathbb E[acXY-adX-bcY+bd]

=ac\mathbb E[XY]-ad\mathbb E[X]-bc\mathbb E[Y]+bd


\mathbb E[aX-b]=a\mathbb E[X]-b


\mathbb E[cY-d]=c\mathbb E[Y]-d


\mathbb E[aX-b]\mathbb E[cY-d]=ac\mathbb E[X]\mathbb E[Y]-ad\mathbb E[X]-bc\mathbb E[Y]+bd


Putting everything together, we find the covariance reduces to


\mathrm{Cov}(aX-b,cY-d)=ac(\mathbb E[XY]-\mathbb E[X]\mathbb E[Y])=ac\mathrm{Cov}(X,Y)


as desired.
