The area of the isosceles triangle is 44 square centimeters. Use the Equation 1/2(8h)=44 to find the height of the triangle.
patriot [66]

area of the issoceles triangle = 44 cm²

or, 1/2 (8h) = 44

or, 8h = 2*44

or, h = 88/8

therefore, h = 11cm

The number of hurricanes that will hit a certain house in the next ten years is Poisson distributed with mean 4. Each hurricane
bulgar [2K]

Answer:

The variance of total loss is 8000000

Step-by-step explanation:

Let

X \to Number of hurricane

Poisson E(X) = 4

Y \to Loss in each hurricane

Exponential E(Y) = 1000

T \to Total Loss

Required

The variance of the total loss

This is calculated as:

Var(T) = Var(E(T|X)) + E(Var(T|X))

Where:

E(T|X) \to Expected total loss given X hurricanes

And it is calculated as:

E(T|X) = E(Y) *N --- Expected Loss in each hurricane * number of loss

Var(T|X) \to Variance of total loss given X hurricanes

And it is calculated as:

Var(T|X) = Var(Y) * N ---- --- Variance of loss in each hurricane * number of loss

So, we have:

Var(T) = Var(E(T|X)) + E(Var(T|X))

Var(T) = Var(E(Y) * N) + E(Var(Y) * N)

For exponential distribution;

Var(Y) = E(Y)^2

So, we have:

Var(T) = Var(E(Y) * X) + E(E(Y)^2 * X)

Substitute values

Var(T) = Var(1000 * X) + E(1000^2 * X)

Simplify:

Var(T) = Var(1000 * X) + 1000^2E(X)

Using variance formula, we have:

Var(T) = 1000^2Var(X) + 1000^2E(X)

For poission distribution:

Var(X) = E(X)

So, we have:

Var(X) = E(X) = 4

The expression becomes:

Var(T) = 1000^2*4 + 1000^2*4

Var(T) = 1000000*4 + 1000000*4

Var(T) = 4000000 + 4000000

Var(T) = 8000000

How to solve this problem​
nevsk [136]

Let C be the center of the circle. The measure of arc VSU is 2+114x, so the measure of the minor arc VU is 360-(2+114x)=358-114x. The central angle VCU also has measure 358-114x.

Triangle CUV is isosceles, so the angles CVU and CUV are congruent. The interior angles of any triangle are supplementary (they add to 180 degrees) so

m\angle VCU+2m\angle CUV=180

\implies m\angle CUV=\dfrac{180-(358-114x)}2=57x-89

UT is tangent to the circle, so CU is perpendicular to UT. Angles CUV and VUT are complementary, so

(57x-89)+(31x+3)=90

\implies88x=176

\implies x=2

So finally,

m\widehat{VSU}=2+114\cdot2=230

degrees.

Of 120 hotel rooms rented one night, some were suites rented for $115 each and the rest were double rooms rented for $85 each. I
ser-zykov [4K]

Answer: A) 23

Step-by-step explanation:

Let x represent the number of suites that were rented.

Let y represent the number of double rooms that were rented.

The total number of rooms that were rented is 120. It means that

x + y = 120

some were suites rented for $115 each and the rest were double rooms rented for $85 each. If the total revenue from the room rentals for this night was $10,890, it means that

115x + 85y = 10890 - - - - - - - - -1

Substituting x = 120 - y into equation 1, it becomes

115(120 - y) + 85y = 10890

13800 - 115y + 85y = 10890

- 115y + 85y = 10890 - 13800

- 30y = - 2910

y = - 2910/-30

y = 97

x = 120 - y = 120 - 97

x = 23
