Answer:

D is the answer

Step-by-step explanation:

Rotation of 180 clockwise about point O

Answer: rotation symmetry

A shape has symmetry if it can be indistinguishable from its transformed image. A shape has rotation symmetry if there exists a rotation less than \begin{align*}360^\circ\end{align*} that carries the shape onto itself.

Answer:

a^2

Step-by-step explanation:

1. if the square root of 5n is now just 5n, that means it was squared.

2. You need to square the other side of the equation which was a.

3. so the box should have a squared.

Answer:

Hmmm... There's no question which leads to the reasoning that there is no answer.

Step-by-step explanation:

Answer:

a) 0.12386 = 12.386% probability that in a year, there will be 3 hurricanes.

b) 5.57 years are expected to have 3 hurricanes, that is, between 5 and 6 years.

c) 5 years is very close to the mean of 5.57, which means that the Poisson distribution works well here.

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

In which

x is the number of sucesses

e = 2.71828 is the Euler number

[tex]\mu[/tex] is the mean in the given interval.

The mean number of hurricanes in a certain area is 5.3 per year.

This means that [tex]\mu = 5.3[/tex]

a. Find the probability that in a year, there will be 3 hurricanes.

This is P(X = 3).

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

[tex]P(X = x) = \frac{e^{-5.3}*5.3^{3}}{(3)!} = 0.12386[/tex]

0.12386 = 12.386% probability that in a year, there will be 3 hurricanes.

b. in a 45-year period, how many years are expected to have 3 hurricanes ?

0.12386 each year. So, for 45 years:

45*0.12386 = 5.57

5.57 years are expected to have 3 hurricanes, that is, between 5 and 6 years.

c. How does the result from part (b) compare to a recent period of 45 years in which 5 years had 3 hurricanes? Does the Poisson distribution work well here?

5 years is very close to the mean of 5.57, which means that the Poisson distribution works well here.

Answer:

X=2

Step-by-step explanation:

Answer:

x=8

Step-by-step explanation:

x + 2 - 2 = 10 - 2 subtract 2 from both sides/ simplify x = 8

Answer:

$85.50

Step-by-step explanation:

57 * .5 = 28.5

28.5 + 57 = 85.5

therefore, the answer would be $85.50

The area of the window is approximately 112.1 meters^2

Step-by-step explanation:

The formula to find the area of a circle is A=πr^2

A = πr^2 = π · 6^2 ≈ 113.09734

A ≈ 113.1

Step-by-step explanation:

Area of the triangle = 1/2 × base × height

Area of the triangle = 1/2 × 6 ft × 8 ft

= 3 ft × 8 ft

= 24 ft²

5 x 3 = 15

Answer:

d

Step-by-step explanation:

First, determine the greatest common factor between the numbers.

Remember, the greatest common factor is just the largest

factor that divides evenly into the two numbers.

In this case, 4 is the largest number so the GCF of our numbers is 4.

For the variables, however, we use the smallest power.

Since we have an x and an x², we use an x.

So our GCF is 4x.

Answer: to understand this we need a picture of the triangle, but without it I know that the only answer that is correct is the 3rd

Answer:

-2x - 4

Step-by-step explanation:

Is your expression

-2 x x = -2x

-2 x 2 = 4

therefore, your expression would be:

-2x - 4

Answer:

Ratio [Model : Actual] = 1:16

Step-by-step explanation:

Given:

Height of model = [tex]2\frac{1}{2}[/tex] inches = 5/2 inches = 2.5 inches

Height of actual status = [tex]3\frac{1}{3}[/tex] feet = 10 / 3 feet

Find:

Ratio [Model : Actual]

Computation:

Height of actual status = [tex]3\frac{1}{3}[/tex] feet = 10 / 3 feet

Height of actual status = [10 / 3] x 12

Height of actual status = 40 inches

Ratio [Model : Actual] = 2.5 / 40

Ratio [Model : Actual] = 1:16
