Let x have a poisson distribution with a variance of 3. find p(x = 2).
RoseWind [281]
Since the variance of a Poisson distribution with rate parameter \lambda is \lambda^2, we know that \lambda=\sqrt3. So,

\mathbb P(X=2)=\dfrac{e^{-\sqrt3}(\sqrt3)^2}{2!}=\dfrac3{2e^{\sqrt3}}\approx0.2654

A playground is rectangular with a length of 24 miles. If the area of the playground is 812 square miles, what is its width? Ans
soldi70 [24.7K]

Answer:

33(5/6) sq miles

Step-by-step explanation:

Area = LxW

812 = 24xW

Divide by 24

W = 33.8333333 ( 33 (5/6)

8 is non repeating

3 is repeating

For nominator subtract the non repeating    (83-8 = 75)

For  denominator :  one 9 for each non repeating,one zero for each repeating (only 3 is repeating,then one zero)

  75/90  = 5/6

Three students, Alicia, Benjamin, and Caleb, are constructing a square inscribed in a circle with center at point C. Alicia draw
True [87]

Benjamin is correct about the diameter being perpendicular to each other and the points connected around the circle.

<h3>Inscribing a square</h3>

The steps involved in inscribing a square in a circle include;

  • A diameter of the circle is drawn.
  • A perpendicular bisector of the diameter is drawn using the method described as the perpendicular of the line sector. Also known as the diameter of the circle.
  • The resulting four points on the circle are the vertices of the inscribed square.

Alicia deductions were;

Draws two diameters and connects the points where the diameters intersect the circle, in order, around the circle

Benjamin's deductions;

The diameters must be perpendicular to each other. Then connect the points, in order, around the circle

Caleb's deduction;

No need to draw the second diameter. A triangle when inscribed in a semicircle is a right triangle, forms semicircles, one in each semicircle. Together the two triangles will make a square.

It can be concluded from their different postulations that Benjamin is correct because the diameter must be perpendicular to each other and the points connected around the circle to form a square.

Thus, Benjamin is correct about the diameter being perpendicular to each other and the points connected around the circle.

Determine whether the two expressions are equivalent. If so, tell what property is applied. If not, explain why. 7 · (6 · t) and
Georgia [21]
The two expressions are equivalent because the associative property of multiplication is applied, which means that no matter where you put the parenthesis, the two expressions will still be equal.
