There are 29 fewer bigstickers on the sticker sheet than the little stickers.there are 62 little stickers on the sheet .how many big stickers are there

Answers

Answer:

33

Step-by-step explanation:

you subtract 29 from 62 because there are 29 less big stickers

There are 33 big stickers on the sticker sheet.

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

Total number of little sticker = 62

And, There are 29 fewer big stickers than the little stickers.

Now,

Since, Total number of little sticker = 62

And, There are 29 fewer big stickers than the little stickers.

So, we can formulate;

Number of big stickers = 62 - 29

                                   = 33 stickers

Thus, There are 33 big stickers on the sticker sheet.

Answers

Trigonometric identity proof: \(sin^2xcos^2x = 1/8 - 1/8cos(40)\) using double angle identities.

How to use trigonometric identity to proof the given problem?

We can use the trigonometric identity sin(2x) = 2sin(x)cos(x) to rewrite the left-hand side of the equation:

\(sin^2(x)cos^2(x) = (sin(2x)/2)^2 * (cos(2x)/2)^2= sin^2(2x)/16\)

We can also use the double angle identity \(cos(2x) = 2cos^2(x) - 1\) to rewrite \(sin^2(2x):\)

\(sin^2(2x) = 1 - cos^2(2x)\)

\(= 1 - (2cos^2(x) - 1)^2\)

\(= 1 - (4cos^4(x) - 4cos^2(x) + 1)\)

\(= -4cos^4(x) + 4cos^2(x)\)

Substituting this expression back into the original equation, we have:

\(sin^2(x)cos^2(x) = sin^2(2x)/16\)

\(= (-4cos^4(x) + 4cos^2(x))/16\)

\(= (1 - cos^2(x))/4 - cos^4(x)/4\)

\(= (1/4) - (1/4)cos^2(x) - (1/4)cos^4(x)\)

Now we use the double angle identity again, this time for cos(4x):

\(cos(4x) = 2cos^2(2x) - 1\)

\(= 2(2cos^2(x) - 1)^2 - 1\)

\(= 8cos^4(x) - 8cos^2(x) + 1\)

Substituting this expression into the preceding equation yields:

\(sin^2(x)cos^2(x) = (1/4) - (1/4)cos^2(x) - (1/4)[(cos(4x) + 8cos^2(x) - 1)/8]= (1/4) - (1/4)cos^2(x) - (1/32)cos(4x) - (1/32)\)

Simplifying this expression, we obtain:

\(sin^2(x)cos^2(x) = 1/8 - (1/8)cos(40)\)

Therefore, we have shown that \(sin^2(x)cos^2(x) = 1/8 - 1/8cos(40)\).

After solving the equations, we know that a total of 25 ladies attended the party.

What are equations?

A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation.

As in 3x + 5 Equals 15, for instance.

Equations come in a variety of forms, including linear, quadratic, cubic, and others.

So, take dudes as x and ladies as y.

Now, form the required 2 equations as follows:
2x + y = 45 ...(1)

x + y = 35 ...(2)

Work on equation (2):

x + y = 35

x = 35 - y

Now, substitute x = 35 - y in equation (1):

2x + y = 45

2(35-y) + y = 45

70 - 2y + y = 45

-y = -25

y = 25

Since ladies were charged $1 for each ticket, then 25 ladies attended the party.

Therefore, after solving the equations, we know that a total of 25 ladies attended the party.

I have a Statistics question and need help with the plots????​

Answers

Definition: Statistical Questions

A statistical question is a question that can be answered by gathering data and a question for which we expect to have variation in the data we collect.

Example 1: Deciding Whether a Question Is Statistical

Determine whether the following is a statistical question: How tall are you?

Answer

To answer this question, we just have to record one height. There will be no variability in the data which means that it is not a statistical question.

Example 2: Deciding Whether a Question Is Statistical

Determine whether the following is a statistical question: What are the heights of the players of your favorite soccer team?

Answer

The answer to this question would be a list of the heights of the players on the team. We expect that there will be variability in the data we collect because not everyone will be the same height. Therefore, this is a statistical question.

Example 3: Deciding Whether a Question Is Statistical

Determine whether the following is a statistical question: In general, how tall are humans?

Answer

An answer to this question could be the mean of the heights of a sample of humans. Therefore, to answer it, we need to collect the data which tells us the heights of different people. Since people are of different heights, there will be variability in the data we collect. Hence, it is a statistical question.

In the above examples, we saw that a statistical question can be answered by a list of data like the heights of a group of people or by a single value that summarizes a set of varied data, like the mean of people’s heights. A question is not statistical if the data we collect to answer it is a single value.

Note that the data collected to answer statistical questions does not have to be numerical. There are two types of data we could collect: numerical and categorical.

Definition: Numerical and Categorical Data

In a numerical data set, all of the data values are numbers. For example, data sets summarizing ages, weights, or heights contain numerical data.

In a categorical data set, the data can be grouped into categories. For example, a data set recording the eye colors of a group of people contains categorical data and each eye color can be thought of as a category.

The first three examples we considered contained questions that could be answered by numerical data. These last two example shows questions that would be answered by categorical data.

Example 4: Deciding Whether a Question Is Statistical

Determine whether the following is a statistical question: What is your favorite subject?

Answer

The answer to this question is a single subject; we do not have to collect data with variability to answer the question. Therefore, it is not a statistical question.

Example 5: Deciding Whether a Question Is Statistical

Determine whether the following is a statistical question: How do students travel to school?

Answer

To answer this question, we would have to collect data about how students travel to school: by car, bike, or bus for example. Since we expect the students’ answers to vary, this is an example of a statistical question.

Penelope goes out to lunch. The bill, before tax and tip, was $16.05. A sales tax of 3% was added on. Penelope tipped 18% on the amount after the sales tax was added. How much tip did she leave? Round to the nearest cent.

Answers

Answer:

2.98

Step-by-step explanation:

First find 3% of 16.05 which is 0.48.

Then add 0.48 to 16.05 which is 16.53.

Then multiply .18 by 16.53 which gets you 2.98

Hope it helps

Answer:

To find the amount of the sales tax, we need to multiply the bill amount by the tax rate of 3% or 0.03:

Sales tax = 0.03 x $16.05 = $0.48

To find the total amount of the bill after the sales tax was added, we need to add the bill amount to the sales tax:

Total bill = $16.05 + $0.48 = $16.53

To find the amount of the tip, we need to calculate 18% of the total bill after the sales tax was added:

Tip = 0.18 x $16.53 = $2.98

Rounding to the nearest cent, Penelope left a tip of $2.98.

B. Repeat the process many times (1000). If 8 correct out of 8 cups rarely occurs, then it is unlikely that the woman was just guessing as to what was poured first.
C. Repeat the process many times (1000). If 8 correct out of 8 cups rarely occurs, then it is likely that the woman was just guessing as to what was poured first.
D. Repeat the process many times (1000). If 4 correct out of 8 cups rarely occurs, then it is unlikely that the woman was just guessing as to what was poured first.

Answers

Answer:

A. Repeat the process many times (1000). If 6 correct out of 8 cups rarely occurs, then it is most likely that the woman was just guessing as to what was poured first.

Step-by-step explanation:

Since tossing a coin 8 times implies 8 cups of tea, with the given conditions.

The sample space = 1000

Then;

             \(\frac{6}{8}\) × 1000 = 750

If 6 correct out of 8 cups occurs (750 out of 1000), the woman got 750 correctly. Thus it can be inferred that it is likely that she knew what was poured first, either the tea or milk.

But, if 6 correct out of 8 cups rarely occurs (i.e 250 out of 1000), then it is most likely that the woman was just guessing as to what was poured first.

What is fixed rate mortgage?

A fixed-rate mortgage is a home loan option with a specific interest rate for the entire term of the loan. Essentially, the interest rate on the mortgage will not change over the lifetime of the loan and the borrower's interest and principal payments will remain the same each month.

Given that, a family borrows $12,843 for an addition to their home.

The loan is to be paid off in monthly payments over a period of 5 years

We know that, 5 years = 60 months

Now, monthly payment = Total money/Number of months

= 12,843/60

= $214.05

Therefore, the monthly payments over a period of 5 years is $214.05.

If it is 80° Fahrenheit, then it is sunny. (Original statement)

Converse: If it is sunny, then it is 80° Fahrenheit. (Valid)

If it is not sunny, then it is not 80° Fahrenheit. (Original statement)

Converse: If it is not 80° Fahrenheit, then it is not sunny. (Invalid)

Counterexample: A day that is not 80° Fahrenheit and not sunny (e.g., 70° and cloudy).

If it is 80° Fahrenheit, then it is sunny. (Original statement)

Converse: If it is sunny, then it is 80° Fahrenheit. (Invalid)

Counterexample: A day that is 80° Fahrenheit and cloudy.

In cases 1 and 2, the original statements and their converses are valid because the relationship between "sunny" and "80° Fahrenheit" holds in both directions. However, in cases 3 and 4, the converses are invalid because there are counterexamples where the second part of the statement (either "not 80° Fahrenheit" or "cloudy") does not necessarily imply the first part ("not sunny" or "80° Fahrenheit").

prove that there exist only five regular polyhedron​

Answers

To prove that there are only these five regular polyhedra, we can consider Euler's polyhedron formula, which states that for any convex polyhedron, the number of vertices (V), edges (E), and faces (F) satisfy the equation V - E + F = 2.

Proving there exist Five Regular Polyhedron

The five regular polyhedra, also known as the Platonic solids, are the only convex polyhedra where all faces are congruent regular polygons, and the same number of polygons meet at each vertex.

The five regular polyhedra are:

1. Tetrahedron: It has four triangular faces, and three triangles meet at each vertex.

2. Cube: It has six square faces, and three squares meet at each vertex.

3. Octahedron: It has eight triangular faces, and four triangles meet at each vertex.

4. Dodecahedron: It has twelve pentagonal faces, and three pentagons meet at each vertex.

5. Icosahedron: It has twenty triangular faces, and five triangles meet at each vertex.

To prove that there are only these five regular polyhedra, we can consider Euler's polyhedron formula, which states that:

"for any convex polyhedron, the number of vertices (V), edges (E), and faces (F) satisfy the equation V - E + F = 2".

For regular polyhedra, each face has the same number of sides (n) and each vertex is the meeting point of the same number of edges (k). Therefore, we can rewrite Euler's formula for regular polyhedra as:

V - E + F = 2  

=>  kV/2 - kE/2 + F = 2  

=>  k(V/2 - E/2) + F = 2

Since each face has n sides, the total number of edges can be calculated as E = (nF)/2, as each edge is shared by two faces. Substituting this into the equation:

k(V/2 - (nF)/2) + F = 2  

=>  (kV - knF + 2F)/2 = 2  

=>  kV - knF + 2F = 4

Now, we need to consider the conditions for a valid polyhedron:

1. The number of faces (F), edges (E), and vertices (V) must be positive integers.

2. The number of sides on each face (n) and the number of edges meeting at each vertex (k) must be positive integers.

Given these conditions, we can analyze the possibilities for different values of n and k. By exploring various combinations, it can be proven that the only valid solutions satisfying the conditions are:

(n, k) pairs:

(3, 3) - Tetrahedron

(4, 3) - Cube

(3, 4) - Octahedron

(5, 3) - Dodecahedron

(3, 5) - Icosahedron

Therefore, there exist only five regular polyhedra.

The mapping diagram represents a relation where x represents the independent variable and y represents the dependent variable.Is the relation a function? Explain.O Yes, because for each input there is exactly one outputYes, because for each output there is exactly one inputO No, because for each input there is not exactly one outputO No, because for each output there is not exactly one input how many drinks are contained in a 60 ounce pitcher The photographer on the ferry charges the same price to take any group's photo. The photographer collected a total of $137.77 for the photographs shown in the line plot. Write and solve an equation to find the charge per picture while stegosaurs had brains that were overall very small, the front part of their brains were enlarged compared to the rest, meaning the likely had: Are spirit filled thermometers safer than mercury filled ones? The vertices of a triangle are P(8, -5), Q(-5, -8), and R(-4, -3). What are the vertices of theimage reflected across the y-axis?A. P(8,-5), Q'(-5, -8), and R'(-4,-3)B. P'(-8,5), Q'(5,8), and R'(4,3)C. P'(8,5), Q'(-5,8), and R'(-4,3)D. P'(-8,-5), Q'(5, -8), and R'(4, -3) A production line is designed to operate 7.5 hours per day and supply a steady demand of 450 units per day. The line efficiency is assumed to be 100%. The production line performs 18 tasks. The task operation times (in minutes) and their precedence relationships are given in Table 1. You are required to determine the number of workstations and the assignment of the tasks to the workstations to balance the production line, and meet customer demands by applying the longest-task-time (LTT), the shortest-task-time (STT), and the Ranked Positional Weights (RPW) methods, respectively.
