Answer:

1/7,776

Step-by-step explanation:

the odds of getting an end zone seat once is 1/6 so you multiply that by itself 5 times to get your answer.

1/6 x 1/6 x 1/6 x 1/6 x 1/6 x 1/6 = (1/6)^5 = 1/7,776.

The probability that a certain student would get end zone seats at all 5 home games is [tex]\frac{1}{7776}[/tex]

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given,

A university football stadium has 1/6 of its students' seats in the end zones

Probability = Number of Favorable outcome / Number of total outcome

Probability that a certain student would get end zone = [tex]\frac{1}{6}[/tex]

Probability that a certain student would get end zone in 5 game = [tex](\frac{1}{6} )(\frac{1}{6} )(\frac{1}{6} )(\frac{1}{6} )(\frac{1}{6} )=\frac{1}{7776}[/tex]

Hence, the probability that a certain student would get end zone seats at all 5 home games [tex]\frac{1}{7776}[/tex]

Answer:

D

Step-by-step explanation:

Let 3x = the length of the first rope

       2x = the length of the second rope

This representation is based on the given that the ratio of the two ropes is 3:2.

3x + 2x = sq rt. 250

5x = sq rt. 250

x = sq rt. 250 / 5

x = sq rt. 25(10) / 5

x = 5 sq rt. 10 /5

The five would be cancelled resulting to:

x =sq rt. 10

Final Answer:

The volume of the box that will hold nine 9.425 cm³ cylindrical containers, each measuring 3 centimeters long, is approximately 108 cm³.

Explanation:

First, we need to find the radius of each cylindrical container since we have its volume and the length. The volume V of a cylinder is given by the formula:
[tex]\[ V = \pi r^2 h \][/tex]
where r is the radius and h is the height (or length) of the cylinder. We are given:
[tex]\[ V = 9.425 \text{ cm}^3 \\\\\[ h = 3 \text{ cm} \][/tex]

We need to solve for r:

[tex]\[ 9.425 = \pi r^2 (3) \\\\\[ r^2 = \frac{9.425}{3\pi} \\\\\[ r^2 = \frac{9.425}{3 \times 3.14159} \\\\\[ r^2 = \frac{9.425}{9.42477} \\\\\[ r^2 \approx 1 \\\\\[ r \approx 1 \text{ cm} \][/tex]

Now we know the radius of one cylindrical container is approximately 1 cm. Although this rounding might lead to a slightly inaccurate result, we'll proceed with this approximation for simplicity's sake.

Since each container is a cylinder with a radius of 1 cm, the diameter of each container is [tex]\( 2 \times 1 = 2 \)[/tex] cm. If we wanted to pack these containers without any wasted space in one layer, we would arrange them in a 3 by 3 grid, given there are 9 containers. The length and the width of the box would then each be 3 times the diameter of one container.

Hence:
Length of box = Width of box = [tex]\( 3 \times 2 \)[/tex] cm = 6 cm.
The height of the box would be equal to the length of one of the containers, which is 3 cm.

Now we can find the volume of the box:
Volume of box [tex]\( V_{\text{box}} \) = Length \( \times \) Width \( \times \) Height[/tex]
[tex]\[ V_{\text{box}} = 6 \text{ cm} \times 6 \text{ cm} \times 3 \text{ cm} \\\\\[ V_{\text{box}} = 36 \text{ cm}^2 \times 3 \text{ cm} \\\\\[ V_{\text{box}} = 108 \text{ cm}^3 \][/tex]
Rounding to the nearest whole number, the volume of the box that will hold nine 9.425 cm³ cylindrical containers, each measuring 3 centimeters long, is approximately 108 cm³.

Final answer:

To find the equation of a line with a given slope and y-intercept in standard form, substitute the values of the slope and y-intercept into the equation y = mx + b.

Explanation:

To write the equation of a line given the slope m and y-intercept b in standard form y = mx + b, you can directly substitute the values of m = 1/2 and b = 3 into the equation.

Substitute m = 1/2 and b = 3 into y = mx + b: y = (1/2)x + 3

Therefore, the equation of the line in standard form is y = (1/2)x + 3.

Step-by-step explanation:

I got it right on my quiz.

Answer:

Step-by-step explanation:

The probability of getting at least 1 correct answer when guessing on a multiple-choice test can be found by subtracting the probability of getting all answers wrong from 1. Whether it is reasonable to expect to pass by guessing depends on the passing percentage and the probability of getting at least 1 answer correct.

To find the probability of getting at least 1 correct answer when making random guesses for 10 multiple-choice test questions, we can look at the probability of getting 0 correct and subtract it from 1. Since each question has 5 possible answers, the probability of getting a question wrong is 4/5. So the probability of getting all 10 questions wrong is (4/5)^10. Therefore, the probability of getting at least 1 correct answer is 1 - (4/5)^10.

To determine if you can reasonably expect to pass the test by guessing, we need to compare the probability of getting at least 1 correct answer to the passing percentage. If the probability of passing is higher than the passing percentage, then it is reasonable to expect to pass by guessing.

Answer:

The cost of the desk is 124 dollars.

Step-by-step explanation:

irst, change this into an equation

tax=1/16x-.31

x equals the cost of the desk without tax:

x+tax=131.44

tax=131.44-x

Set the first equation equal to the second:

1/16x-.31=131.44-x

Solve for x:

17/16x=131.75

x=$124

Hope that helps

The equivalent percentage value for the decimal number 1.16 is 116% which is obtained by multiplying the decimal by 100. Before including the tax the price of the desk was $60.99.

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100.

And to convert a fraction or a decimal into percentage, they are multiplied by 100.

Given that,

The amount paid by Rachel for a desk is $131.44.

Suppose the price of desk is before adding the tax is x.

Then, as per the problem the following expression can be written for the tax amount as,

1.16x - 0.31  

Now, the expression for the price of desk after tax is,

x + 1.16x - 0.31  = 131.44

⇒ 2.16x =  131.44 +  0.31

⇒ 2.16x = 131.75

⇒ x = 131.75 / 2.16

⇒ x = 60.99

Hence, the price for the desk before adding the tax is $60.99.

Answer:

B) 2 x-intercepts

The cost of each apple will be 20 cents per apple. Then the correct option is C.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

Conversion means to convert the same thing into different units.

If apples are on sale at 15 for $3.

We know that $1 = 100 cents

Then the number of the cents in 3 dollars will be

⇒ 3 x 100

⇒ 300 cents

Then the cost of each apple will be the ratio of the 300 cents and 15 apple.

⇒ 300 / 15

⇒ 20 cents per apple

Thus, the cost of each apple will be 20 cents per apple.

Then the correct option is C.

Answer:

[tex]x=9.5[/tex]  

[tex]y=8.8[/tex]  

Step-by-step explanation:

We have been given a diagram of triangles. We are asked to find the value of x and y.

We can see that triangle JKL and JMN share same vertex that is angle J. Since line KL is parallel to line MN, therefore, there corresponding angles will be equal.

Therefore, Angle-angle-angle similarity [tex]\Delta JKL\sim \Delta JMN[/tex].

Since corresponding sides of similar triangles are always proportional, so we can set a proportion for the sides of our given triangles as:

[tex]\frac{x-2}{5}=\frac{12}{8}[/tex]

Upon cross multiplying our equation we will get,

[tex]8(x-2)=12*5[/tex]

[tex]8x-16=60[/tex]

Let us add 16 to both sides of our equation.

[tex]8x-16+16=60+16[/tex]

[tex]8x=76[/tex]

Let us divide both sides of our equation by 8.

[tex]\frac{8x}{8}=\frac{76}{8}[/tex]  

[tex]x=9.5[/tex]  

Therefore, x equals 9.5.

We can also set a proportion to solve for y as:

[tex]\frac{y}{22}=\frac{8}{12+8}[/tex]

[tex]\frac{y}{22}=\frac{8}{20}[/tex]

Upon cross multiplying our equation we will get,

[tex]20y=22*8[/tex]

[tex]20y=176[/tex]

Let us divide both sides of our equation by 20.

[tex]\frac{20y}{20}=\frac{176}{20}[/tex]

[tex]y=8.8[/tex]

Therefore, y equals 8.8.
