An urn contains 8 green and 9 white balls. Six balls are randomly drawn from the urn in succession, with replacement. That is, after each draw, the selected ball is returned to the urn. What is the probability that all 6 balls drawn from the urn are white? Round your answer to three decimal places.

Answers

Answer:

The probability is 0.022

Step-by-step explanation:

Firstly, we need to get the total number of balls in the urn

mathematically, we have this as ;

8 + 9 = 17

now, the probability of selecting a white ball will be the number of white balls divided by the total number of balls

Mathematically, we have this as 9/17

Now, since the event is carried out with replacement, the probability for the six times is the same

So, we have the probability as;

(9/17)^6 = 0.022

Write each polynomial in standard form.

What is the solution to 4|0.5x – 2.5| = 0?

x = 1.25
x = 5
x = –1.25 or x = 1.25
x = –5 or x = 5

Answers

Answer:

B. X=5

Step-by-step explanation:

To solve this problem, first, you have to isolate the value of x from one side of the equation.

[tex]\sf{4|0.5x-2.5|=0}[/tex]

First, divide by 4 from both sides of an equation.

[tex]\sf{\dfrac{4|0.5x-2.5|}{4}}=\dfrac{0}{4}[/tex]

Solve.

|0.5x-2.5|=0

0.5x-2.5=0

x=5

Therefore the correct answer is x=5.

what is the area of a square with an apothem length of 14 inches?

Answers

Answer:

784

Step-by-step explanation:

A = 1/2ap       A = area , a = apothem , p = perimeter  

a = 1/2s          a = apothem length , s = side length

14 = 1/2s , 14(2) = 1/2s(2) , 28 = s

p = 4(s) , p = 4(28) , p = 112

A = 1/2ap , A = 1/2(14)(112) , A = 784

                 or

A = s^2 , A = 28^2 , A = 784

The area of a square with an apothem length of 14 inches is 784 inches.

What is apothem?

The perpendicular from the center of a regular polygon to one of the sides.

As, A = 1/2*a*p      

where, A = area , a = apothem , p = perimeter  

Also, a = 1/2s          

where, a = apothem length , s = side length

14 = 1/2s

14*2=s

s=28 inches.

Now, perimeter of square

p = 4(s)

p = 4(28)

p = 112 inches

Now, Area of square,

A = 1/2ap

A = 1/2*(14)*(112)

A = 784 inches

Hence, the area of square is 784 inches.

A rectangular banner covers an area of 2 7/8ft2. The length of the banner is 3/4ft. What is the width of the banner in ft?

Answers

Answer:

Width of the rectangular banner is [tex]3\frac{5}{6}[/tex] ft.

Step-by-step explanation:

Area of the rectangular banner = [tex]2\frac{7}{8}[/tex] square feet

                                                    = [tex]\frac{23}{8}[/tex] square feet

Area of rectangle is given by,

Area = Length × Width

Length of the banner = [tex]\frac{3}{4}[/tex] feet

From the formula,

[tex]\frac{23}{8}=\frac{3}{4}\times W[/tex]

W = [tex]\frac{\frac{23}{8} }{\frac{3}{4} }[/tex]

    = [tex]\frac{23}{8}\times \frac{4}{3}[/tex]

    = [tex]\frac{23}{6}[/tex]

     = [tex]3\frac{5}{6}[/tex] ft

Therefore, width of the rectangular banner is [tex]3\frac{5}{6}[/tex] ft

home after 3 years.
a.$137027.97
b.$275503.80
c.$114449.19
d.$3385800

Answers

Answer:

The value after three years is $137,027.97

Step-by-step explanation:

Here, we want to get the value of the home after 3 years

Generally, we have the exponential formula as follows;

y = P(1 + r)^t

where P is the original cost which is $124,400

r is the rate of increase which is 3% = 3/100 = 0.03

t is the time which is 3 years

Substituting these values;

y = 125400(1 + 0.03)^3 = $137,027.97

Which statement about the graphs is true? NEED HELP!
Graph A is a valid density curve because the part of the graph from 2 to 6 is below the horizontal axis.
Graph A is not a valid density curve because the part of the graph from 1 to 2 is above the horizontal axis.
Graph B is not a valid density curve because part of the horizontal axis has negative values.
Graph B is a valid density curve because the curve is above the horizontal axis, and the area under the curve is 1.

Answers

Answer:

Graph B is a valid density curve because the curve is above the horizontal axis, and the area under the curve is 1.

Step-by-step explanation:

A density curve is a graph that shows probability.

There are a few properties that those curves have:

The curves are normalized, which means that the area inside the curve is always equal to 1  (or the 100% of possibilities).

And the probabilities are always defined with positive numbers between 0 and 1, which means that we can not have a density curve with elements below the horizontal axis.

From this, we can conclude that graph A is not a density curve (but neither of the two given options for graph A are correct, then we can discard these).

Now let's look at graph B.

We can see that all points are above the horizontal axis, so that is good.

Now let's compute the area inside the curve.

We can see two triangles, remember that the area of a triangle of base b and height h is:

A = (b*h)/2

To calculate the base in the image, just take the difference between the rightmost vertex and the left vertex.

The base of the left triangle is b = (-3 - (-5)) = 2, and the height is h = 0.25

Then the area is:

A1 = (2*0.25)/2 = 0.25

The base of the right triangle is b = (3 - (-3)) = 6, and the height is h = 0.25

Then the area of this triangle is:

A2 = (6*0.25)/2 = 0.75

If add these areas, we get:

Total area = A1 + A2 = 0.25 + 0.75 = 1

Total area = 1

So we have an area under the curve equal to 1, which means that graph B is a valid density curve.

And the correct option is then:

Graph B is a valid density curve because the curve is above the horizontal axis, and the area under the curve is 1.

Are the two triangles similar? How do you know (What Theorem)?

Answers

Answer:

They are similar because of the SAS triangle similarity theorem.

Step-by-step explanation:

The angles in the interconnection of the two triangles are the same because they have the same vertex and lines.

The two sides are similar by a ratio of 1.5.

9/6 and 6/4 both equal to 1.5, which means that they have the same ratio.

Because there is a side that's similar, an angle that's congruent, and then a side that's similar, you can say that the triangles are similar basing on the SIDE-ANGLE-SIDE triangle similarity theorem.
