There are 4 red, 6 green, and 5 yellow pencils in a jar. Once a pencil is selected, it is not replaced. Find each probability.

Answers

Answer 1
Final answer:

This question deals with calculating probabilities of selecting specific colors of pencils from a jar without replacement. First, find the probability of each of the events separately, and then find their joint probability if events are happening successively by multiplying the individual probabilities.

Explanation:

The subject of this question is probability, and it belongs to the field of Mathematics. You're asked to calculate the probability of selecting certain colors of pencils from a jar. The jar contains 4 red, 6 green, and 5 yellow pencils, making a total of 15 pencils. When a pencil is selected, it is not replaced back in the jar, affecting the probabilities of the following selections.

As an example, the probability of drawing a red pencil first (P(red)) would be the total number of red pencils divided by the total number of pencils which equals 4/15. If you then wanted to select a green pencil, the total number of pencils is now 14 (broader outcome space) as a pencil has been removed and not replaced. So, the probability of drawing a green pencil after a red one (P(green|red)) would be 6/14.

To find the probability of both events happening consecutively (drawing a red pencil then a green one), you would multiply the two probabilities together i.e., P(red and green) = P(red) · P(green|red). Applying the same steps to other combinations and you will be able to calculate all the different probabilities.

The rent for an apartment is $800 per month. The landlord charges one month’s rent as a deposit plus a nonrefundable damage cost of $250. The expression 800(n + 1) + 250 represents the cost of the renting the apartment for n months. Simplify the expression.
How much does the apartment cost to rent for 2 years?

Answers

Final answer:

The cost of renting the apartment for n months can be simplified to 800n + 1050. To rent the apartment for 2 years, the cost is $20,250.

Explanation:

To simplify the expression, we can distribute the 800 to both terms inside the parentheses:

800 * n = 800n800 * 1 = 800

Combining these terms gives us:

800n + 800 + 250

By combining like terms, we get the simplified expression:

800n + 1050

To find the cost of renting the apartment for 2 years (24 months), we substitute n = 24 into the simplified expression:

800(24) + 1050 = 20,250

Therefore, the apartment costs $20,250 to rent for 2 years.

For the​ polyhedron, use​ Euler's Formula to find the missing number. ​faces: __ ​edges: 12 ​vertices: 9

Answers

There are 5 faces of a given polyhedron.

What is Polynomial?

A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminate in mathematics. Majorly used polynomials are binomial and trinomial.

Euler's formula states that for a polyhedron with V vertices, E edges, and F faces,

V - E + F = 2.

In this case, we know that the polyhedron has 12 edges and 9 vertices. Let's use Euler's formula to solve for the number of faces:

9 - 12 + F = 2

F = 2 + 12 - 9

F = 5

Therefore, the polyhedron has 5 faces.

If the technician charged $327.50, then the technician worked ___
hours.​

Answers

If the technician charges $327.50, then the technician worked 5.95 hours.

To determine how many hours the computer technician worked, we need to set up an equation based on the information provided. Let:

- [tex]\( F \)[/tex] represent the flat rate for home visits.

- [tex]\( h \)[/tex] represent the number of hours worked.

- [tex]\( 55h \)[/tex] represent the hourly charge ($55 per hour).

The total charge is given as $327.50. The equation for the total charge is:

[tex]\[F + 55h = 327.50\][/tex]

Without the flat rate [tex]\( F \)[/tex] provided, we can't determine [tex]\( h \)[/tex] exactly. However, let's assume that [tex]\( F \)[/tex] is included in the total cost as a constant and solve for [tex]\( h \)[/tex] based on the given rate per hour.

First, let's isolate [tex]\( h \):[/tex]

[tex]\[55h = 327.50 - F\\\\h = \frac{327.50 - F}{55}\][/tex]

Since the exact flat rate [tex]\( F \)[/tex] isn't given, let's assume it's zero for this case:

[tex]\[h = \frac{327.50}{55}\][/tex]

Now, calculate [tex]\( h \):[/tex]

[tex]\[h = \frac{327.50}{55} = 5.95 \text{ hours}\][/tex]

Therefore, if the technician charges $327.50 for 5.95 hours worked and assuming no flat rate, the technician worked approximately [tex]\( 5.95 \)[/tex] hours.

The complete question is:

A computer technician charges a flat rate for home visits plus $55 per hour. If the technician charged $327.50, then the technician worked how many hours?

A special form of the ellipse is called?

Answers

A circle is a special form of an ellipse, occurring when both focal points of an ellipse coincide at one point, making its eccentricity zero.

A special form of the ellipse is called a circle. This occurs when the two focal points of an ellipse coincide at a single point, which is also the center of the circle. In mathematical terms, an ellipse whose equation is scaled down in one direction, transforming it into x² + y² = a², represents a circle with center at the origin and radius a.

Kepler's first law regarding planetary orbits also refers to this special case of an ellipse. It states that planets follow an elliptical path with the Sun at one of its focal points. When both focal points are at the same location, indicative of zero eccentricity, the orbit is not elliptical but circular.

The properties of an ellipse are crucial in understanding celestial mechanics and orbits, reflecting the significance of this special case in both mathematics and astronomy.

Which statement about histograms is true?

-Data is organized in categories
-Data appears as bars that are all about the same height
-Data is organized in equal intervals
-Data appears as bars that do not touch


Answers

Answer:

The third one is correct, the others bend the truth as they can touch but not overlap. As the third one states 'They are organized in equal intervals.'  this means they share an equal growth opportunity within their own column, their own height and nominated place within the histogram. The bars are of equal width and correspond to the equal class intervals. But on rare occasions like size classes they can be shown as a wider variant within their groups. Example would be showing a wider column say on classes at a school as the width and data being achieved forces a true event of variant sizes in education upon the base of the graph, this rarely applies to staff graphs as planning for schools is a wider data share than say offices using these types of graphs. Work development would use just data percentages along with the frequencies is one example so group size are stated in the reports to support more specific data in the graphs instead.

To display numerical data that has been organized into equal intervals. The bars should touch the adjacent bars but not overlap. These intervals allow you to see the frequency distribution of the data, or how many pieces of data are in each interval.

A cylinder has a base diameter of 8ft and a height of 20ft. What is its volume in cubic ft, to the nearest tenths place?

Answers

Final answer:

The volume of a cylinder with a base diameter of 8ft and height of 20ft is approximately 1005.3 cubic feet.

Explanation:

The volume of a cylinder can be calculated using the formula Volume = πr²h where π represents approximately the number 3.14, 'r' signifies the radius of the cylinder, and 'h' denotes the height of the cylinder.

In this case, the diameter of the cylinder is given as 8 feet, so the radius will be half of that which is 4 feet. The height is specified as 20 feet.

Substitute these values into the equation:

Volume = π * (4 ft)² * 20 ft

This simplifies to:

Volume = 3.14 * 16ft² * 20ft

By multiplying these values, we get the volume equals the product of these numbers:

Volume ≈ 1005.3 cubic ft. Hence, the volume of this cylinder to the nearest tenths is 1005.3 cubic feet.

The volume of a cylinder with an 8ft diameter and 20ft height is approximately 1005.3 cubic feet, rounded to the nearest tenths place.

To calculate the volume of a cylinder, we use the formula V = πr²h, where V represents the volume, r is the radius of the cylinder's base, and h is the height of the cylinder. Given that the diameter of the cylinder is 8ft, the radius is half of the diameter, which is 4ft. Now, using the formula:

V = πr²h

V = π(4ft)² × 20ft

V = π16ft² × 20ft

V = π 320ft³

V = 1005.31ft³

Therefore, the volume of the cylinder is approximately 1005.3 cubic feet, rounded to the nearest tenths place.

Answers

The expression could represent the dog kennel is (x + 2)(x + 6)²

What expression could represent the dog kennel

From the question, we have the following parameters that can be used in our computation:

Volume = x³ + 14x² + 60x + 72

Height = x + 2

Dividing the Volume by the Height , we have

            x² + 12x+ 36

x + 2  |  x³ + 14x² + 60x + 72

            x³ + 2x²

--------------------------------------------------------

                       12x² + 60x + 72

                       12x² + 24x

--------------------------------------------------------

                       36x + 72

                       36x + 72

--------------------------------------------------------

                                  0

So, we have

x³ + 14x² + 60x + 72 = (x + 2)(x² + 12x+ 36)

Expand

x³ + 14x² + 60x + 72 = (x + 2)(x + 6)²

Hence, the expression could represent the dog kennel is (x + 2)(x + 6)²

600g/$4.25=1000g/? (finding the question mark which will be "x")

you cross multiply so 600x = 4.25×1000

600x = 4250

then cancel out the 600 so x is left, since the 600 is multiplying into the x, you would divide it out to cancel. so

600x=4250

_________     <(dividing)

600     600

so it would be

x= 7.08

which means it is $7.08 which is NOT better for value because it is 9 cents more than just buying the 1kg.

Mary bakes a chocolate cake, a vanilla cake, and a strawberry cake. Each cake is the same size. Angela eats four-eighths of the chocolate cake, two-eighths of the vanilla cake, and two-fourths of the strawberry cake. David eats one-fourth of the chocolate cake, three-eighths of the vanilla cake, and one-half of the strawberry cake. Who eats more cake, Angela or David? How much more cake? How much of each cake is left? Show all your mathematical thinking.

Answers

After Angela and David eat their portions, there is [tex]\( \frac{1}{4} \)[/tex] of the chocolate cake, [tex]\( \frac{3}{8} \)[/tex] of the vanilla cake, and [tex]\( \frac{1}{4} \)[/tex] of the strawberry cake left.

To compare how much cake Angela and David eat, let's calculate the total fraction of each cake consumed by each person:

For Angela:

- Chocolate cake: [tex]\( \frac{4}{8} = \frac{1}{2} \)[/tex]

- Vanilla cake: [tex]\( \frac{2}{8} = \frac{1}{4} \)[/tex]

- Strawberry cake: [tex]\( \frac{2}{4} = \frac{1}{2} \)[/tex]

Total cake eaten by Angela: [tex]\( \frac{1}{2} + \frac{1}{4} + \frac{1}{2} = \frac{5}{4} \)[/tex]

For David:

- Chocolate cake: [tex]\( \frac{1}{4} \)[/tex]

- Vanilla cake: [tex]\( \frac{3}{8} \)[/tex]

- Strawberry cake: [tex]\( \frac{1}{2} \)[/tex]

Total cake eaten by David: [tex]\( \frac{1}{4} + \frac{3}{8} + \frac{1}{2} = \frac{13}{8} \)[/tex]

Since [tex]\( \frac{13}{8} > \frac{5}{4} \),[/tex] David eats more cake than Angela.

To find out how much more cake David eats:

- David eats [tex]\( \frac{13}{8} - \frac{5}{4} = \frac{13}{8} - \frac{10}{8} = \frac{3}{8} \)[/tex]  more cake.

To calculate how much of each cake is left:

- Chocolate cake: [tex]\( 1 - \frac{4}{8} - \frac{1}{4} = \frac{1}{4} \)[/tex]

- Vanilla cake: [tex]\( 1 - \frac{2}{8} - \frac{3}{8} = \frac{3}{8} \)[/tex]

- Strawberry cake: [tex]\( 1 - \frac{2}{4} - \frac{1}{2} = \frac{1}{4} \)[/tex]

So, after Angela and David eat their portions, there is [tex]\( \frac{1}{4} \)[/tex] of the chocolate cake, [tex]\( \frac{3}{8} \)[/tex] of the vanilla cake, and [tex]\( \frac{1}{4} \)[/tex] of the strawberry cake left.

What is a function?

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

In other terms, a function is a relationship between variables, and the type of relationship that exists between the variables defines the function, such as y = sinx and y = x +6.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

Given the function

f(x) = 1/2 x - 5

value of function at x = 6

f(6) = (1/2)6 - 5

f(6) = 3 - 5 = -2
