Answers

Answer 1

Thus, the number of 6-digit numbers that can be formed using the digits 0, 1, 2, 5, 7 and 9 which are divisible by 11 and no digit is repeated is 20.

What is the number of 6 digit numbers that can be formed using the digits 0, 1, 2, 5, 7 and 9 which are divisible by 11 and no digit is repeated?There are 1200 6-digit numbers that can be formed using the digits 0, 1, 2, 5, 7, and 9.Using the formula for a 2-digit number, namely A and B, the number must satisfy A - B = 0,11 or -11.

There is a pattern, therefore, there are 100 numbers that satisfy each. It's because the numbers 0, 1, 2, 5, 7, and 9 are such that the sum of the odd digits minus the sum of the even digits is always either 0, 11, or -11. This is only possible if there is an even number of odd digits or an even number of even digits.

There are 6C3 ways to pick 3 odd digits from {1,5,7,9} and 3C3 ways to pick 3 even digits from {0,2}. By taking the product of these values, we can find the total number of possibilities:[tex]6C3 × 3C3 = 20 × 1 = 20[/tex]

Ariel got a job at a restaurant and needed to purchase black dress pants and red shirts to work there. She found shirts she liked for $7.50 each and pants she liked for $18. She needs at least 2 shirts, at least 2 pairs of pants, and wants to spend no more than $150.

Answers

Ariel got a job at a restaurant and needed to purchase 2 shirts and 2 pairs of pants.

Let's use the variable "x" to represent the number of shirts Ariel buys and "y" to represent the number of pants she

buys.

Then, we can write the following system of inequalities:

2 ≤ x ≤ ∞ (Ariel needs at least 2 shirts)

2 ≤ y ≤ ∞ (Ariel needs at least 2 pairs of pants)

7.50x + 18y ≤ 150 (Ariel wants to spend no more than 150)

Now, we can graph the system of inequalities on a coordinate plane to find the feasible region, which represents all the possible combinations of shirts and pants that satisfy the given constraints.

The feasible region is shaded in the graph below:

graph {(150-7.5 × x)/18}

As you can see from the graph, the feasible region is a quadrilateral with vertices at (0, 8.33), (2, 7), (8, 3), and (25, 0).

This means that Ariel can buy any combination of shirts and pants within this region and still meet her requirements.

To find the optimal solution, we can simply check the corner points of the feasible region and see which combination gives us the most value for our money.

For example, if Ariel buys 2 shirts and 2 pants (i.e., the point (2, 2) on the graph), she will spend:

7.50(2) + 18(2) = 51

This is within her budget of 150 and meets her requirement of at least 2 shirts and 2 pants.

Therefore, the answer is: Ariel should buy 2 shirts and 2 pairs of pants.

What is the area, in square centimeters, of the shape

Answers

The value of the area of the triangle in square cm is 4.51 sq. cm.

What is area of triangle?

On a two-dimensional plane, a triangle's area is the area that it completely encloses. A triangle is a closed form with three sides and three vertices, as is common knowledge. The entire area occupied by a triangle's three sides is referred to as its area. Half of the product of the triangle's base and height provides the standard formula for calculating the area of the triangle.

The area of the triangle is given by:

A = 1/2(b)(h)

Substitute the value of b = 4.1 cm and h = 2.2 cm we have:

A = 1/2(4.1)(2.2)

A = (4.1)(1.1)

A = 4.51 sq. cm.

Hence, the value of the area of the triangle in square cm is 4.51 sq. cm.

The triangle with angle measures of 30°, 60°, and 90° is a special type of right triangle called a "30-60-90 triangle"

The triangle with angle measures of 45°, 45°, and 90° is another special type of right triangle called an "isosceles right triangle".

The triangle with angle measures of 30°, 60°, and 90° is a special type of right triangle called a "30-60-90 triangle". In this type of triangle, the smallest angle is 30°, the second angle is 60°, and the largest angle is always 90°.

The triangle with angle measures of 45°, 45°, and 90° is another special type of right triangle called an "isosceles right triangle". In this type of triangle, both of the smaller angles are equal and are always 45°, while the largest angle is always 90°.

However, if a triangle has a 90° angle, but the other angle measures cannot be determined, then there are many different possibilities for the triangle's other two angles. For example, one possible set of angles for such a triangle is 30°, 60°, and 90° (as in the first example), but there are many other sets of angles that could also work.

Answers

Answer:

A one-sample t-confidence interval for means

Step-by-step explanation:

The appropriate statistical procedure to answer the research question in the heart rate scenario depends on the type of comparison being made. If the comparison is between two separate groups, a two-sample t-test or a two-sample t-confidence interval for means should be used.

However, if the comparison is within the same group, a one-sample t-test or a one-sample t-confidence interval for means would be appropriate. In the heart rate scenario, the research question is not clearly stated. However, assuming that the objective is to compare the heart rate of a group of individuals to a known population mean, a one-sample t-test or a one-sample t-confidence interval for means would be the appropriate statistical procedure.

The steps for a one-sample t-test are as follows: (1) State the null and alternative hypotheses, (2) Collect data and calculate the sample mean and sample standard deviation, (3) Calculate the t-value using the formula t = (sample mean - population mean) / (sample standard deviation / square root of sample size), (4) Determine the degrees of freedom, (5) Determine the p-value using a t-distribution table or a statistical software, (6) Compare the p-value to the significance level, and (7) Draw a conclusion based on the p-value and the significance level.

A one-sample t-confidence interval for means follows similar steps but instead of calculating a t-value, a confidence interval is calculated.

Therefore, to answer the research question in the heart rate scenario, a one-sample t-test or a one-sample t-confidence interval for means should be used.

The preimage shown below is dilated by a scale factor of 1/2 about the center (1,-5). What is the coordinate location of the point C'.

Type your answer as an ordered pair, (x,y), with no spaces.

Answers

With Scaling Factor = 1/2,  the coordinate location of the dilated point C' is (2, -3).

What exactly is scaling factor?

In mathematics, a scaling factor is a ratio that describes how much a figure or object has been enlarged or reduced in size. A scaling factor is typically expressed as a fraction or decimal that represents the relative change in size between the original figure and the new, scaled figure.

Now,

To find the coordinate location of the dilated point C', we can use the following formula:

C' = (1 - k) * C + k * A

where:

C is the original point (3, -1)

A is the center of dilation (1, -5)

k is the scaling factor (1/2)

then,

C' = (1 - 1/2) * (3, -1) + (1/2) * (1, -5)

C' = (1/2) * (3, -1) + (1/2) * (1, -5)

C' = [(1/2) * 3 + (1/2) * 1, (1/2) * (-1) + (1/2) * (-5)]

C' = [(3/2) + (1/2), (-1/2) + (-5/2)]

C' = (2, -3)

Therefore, the coordinate location of the dilated point C' is (2, -3).

To determine the day of the week that is 31 days from a Monday, we can use the fact that there are seven days in a week. Since 31 is not evenly divisible by 7, we cannot simply add or subtract a certain number of days to find the day of the week.

Instead, we must use modular arithmetic. Specifically, we can take the remainder of 31 divided by 7, which is 3. This means that after 31 days, we will be three days ahead of Monday, so the day will be Thursday. Therefore, the day of the week that is 31 days from a Monday is Thursday.

The list with the smallest standard deviation is the following: 16, 12, 13, 16, 14, 15, 16, 14, 14, 13.

What is standard deviation?

Standard deviation is a statistical measure of the variability of a set of data values. It's a step-by-step process for determining how far each value is from the mean. It is important since it may reveal the amount of variability in a set of data. The formula for calculating standard deviation is as follows:

σ=√∑(x−μ)²nσ=√∑(x−μ)²n

In this equation, x represents the values in the data set, μ represents the mean of the data set, and n represents the number of values in the data set. Let us now compute the standard deviation of each of the given data sets, starting with the first one. We can utilize the formula given above to do so:

6, 19, 9, 18, 19, 9, 17, 18, 17, 15                        μ = 15.8,σ = 4.83 (rounded to two decimal places)

To find the probability that a respondent has a pet given that they have had a pet, we need to use Bayes' theorem:

[tex]P(Pet | HadPet) = P(HadPet | Pet) \times P(Pet) / P(HadPet)[/tex]

We are given that 33% have a pet now and have had a pet, which means P(HadPet | Pet) = 1 (if someone has a pet, they have had a pet).

We are also given that 87% have had a pet, which means P(HadPet) = 0.87. Finally, we need to find P(Pet), the probability that someone has a pet:

[tex]P(Pet) = 0.33 + 0.13 = 0.46[/tex]

(we add 0.13 because some respondents have had a pet in the past but don't currently have one)

Now we can plug these values into Bayes' theorem:

[tex]P(Pet | HadPet) = 1 \times 0.33 / 0.87 = 0.38[/tex]

Hence, the force that results has a magnitude of about 10.3 newtons (rounded to the nearest 10th of a newton).

What does magnitude imply?

"How much of a quantity" is the definition of magnitude. For instance, the amount of data can be utilized for assessing the speeds of a car and a bicycle. In addition, it can be used to express how far an object has come or how much weight it carries relative to its size.

The law of cosines, which connects a triangle's sides and angles, can be used to calculate the size of the resulting force:

A2 + B2 - 2ab*cos = C2 (C)

We can define the 8.6 newtons in this case as side a, the 3.5 newtons as side b, and the angle between them as C:

a = 8.6 N b = 3.5 N

C = 58°

By applying the law of cosines, we may determine the length of the resultant force or side c.

The triangles are similar by SAS similarity and the similarity statement is ΔABC ~ ΔPQR.

We can determine the similarity of the triangles by checking if they satisfy the conditions of AA, SAS, or SSS similarity.

AA Similarity: If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

Looking at the triangles, we can see that angle A is congruent to angle P, and angle B is congruent to angle Q. However, we cannot conclude that the triangles are similar by AA similarity because we do not know if the third pair of angles are congruent.

SAS Similarity: If two pairs of sides of one triangle are proportional to two pairs of sides of another triangle, and the included angles are congruent, then the triangles are similar.

Looking at the triangles, we can see that:

AB is proportional to PQ (since AB/PQ = 4/5)

BC is proportional to QR (since BC/QR = 3/4)

Angle BAC is congruent to angle QPS (since they are vertical angles)

The area of a square is 118 m2. Kelli says that each side of the square is approximately 10.9 m. Is Kelli correct?
Explain how you know.

Answers

Answer:

Kelli is close to the truth if one considers that the approximation of 118.81 is equal to 118

Step-by-step explanation:

Area of a square = side²

Then:

let´s see if:

118 = 10.9²

10.9² = 10.9 * 10,9 = 118.81

118 is approximately equal to 118.81

To determine if Kelli is correct, we need to find the length of each side of the square given its area.

The area of a square (A) is calculated by squaring the length of one of its sides (s):

A = s^2

We know that the area of the square is 118 m². To find the length of a side, we need to take the square root of the area:

s = √A
s = √118

Approximately,

s ≈ 10.86 m

Kelli's estimation of each side being approximately 10.9 m is close but slightly off. The correct value is closer to 10.86 m. However, considering that it's an approximation, Kelli's estimate can be considered reasonably accurate.

Find the shaded area

Answers

The shaded area of the figure is equal to 297 square centimeters.

How to determine the shaded area

In this question we find a shaded figure, whose area can be found as a subtraction of the areas of two triangles from the area of a rectangle. The area formulas are defined below:

Rectangle

A = b · h

Triangle

A = 0.5 · b · h

Where:

b - Width, in centimeters.h - Height, in centimeters.A - Area, in square centimeters.

Now we proceed to compute the shaded area:

A = (18 cm) · (22 cm) - 0.5 · (9 cm) · (13.2 cm) - 0.5 · (9 cm) · (8.8 cm)

A = 297 cm²

b. Graph the data.

please i have this assignment due tomorrow and i really need ur help!! if any it would be really helpful!!​

Answers

The best graph to use to display this data of costs and quantity of books offered for sale in a bookstore is a scatter plot.

a. Since the data includes prices and the number of books sold at each price, a scatter plot would be the most appropriate type of graph for displaying this data. A scatter plot is used to show the relationship between two quantitative variables, where one variable is plotted on the x-axis and the other variable is plotted on the y-axis. In this case, we can plot the price of each book on the x-axis and the number of books sold at each price on the y-axis. This will allow us to see if there is a relationship between the price of the book and the number of books sold.

b. In the scatter plot, each point represents a different price and the corresponding number of books sold at that price. We can see that there is a negative relationship between price and the number of books sold - as the price increases, the number of books sold decreases. We can also see that there are a few outliers, such as the point at $5.00 where 39 books were sold and the point at $17.25 where 18 books were sold.

the set of all elements of interest in a study is . a. a sample b. set notation c. a set of interest

Answers

The statement describes a set of interest in a study, which is the set of all elements being investigated or under consideration. It is not a sample, which refers to a subset of the population being studied.

The set of all elements of interest in a study is called the population. It refers to the entire group of individuals, objects, or measurements that are being studied and from which data can be collected. The population can be finite or infinite and can include people, animals, plants, materials, or any other object or concept of interest. In statistical analysis, researchers use samples of the population to make inferences or draw conclusions about the entire population. By selecting a representative sample, researchers can reduce the cost and time required for data collection and analysis while still obtaining valid and reliable results.

How do fractions compare to percentages?

Answers

Fractions and percentages are different ways of representing the same value.

A percentage is simply another way of writing a fraction with a denominator of 100. For example, 25% is equivalent to the fraction 25/100 or the reduced fraction 1/4. Similarly, 75% is equivalent to 75/100, which can be reduced to 3/4.

When comparing fractions and percentages, it's important to remember that they represent the same value, but they are expressed in different ways. Fractions are typically used when dealing with ratios or proportions, while percentages are used to express a part of a whole in terms of hundredths.

For example, if you have 6 out of 10 apples, you can express this as a fraction (6/10) or as a percentage (60%). Both the fraction and the percentage represent the same value: 6 out of 10 or 60 out of 100.

To compare fractions and percentages, you can convert between them if necessary using the fact that 1% is equivalent to 1/100. Otherwise, you can use whichever representation is most appropriate for the context of the problem you are trying to solve.

Volume of the award is 510.25 square centimeter.

Define volume

Volume is a measure of the amount of space that a three-dimensional object occupies. It is a physical quantity that is typically measured in cubic units, such as cubic meters (m³) or cubic centimeters (cm³).

The volume of an object is calculated by multiplying its three dimensions together. For example, the volume of a rectangular prism can be calculated by multiplying its length, width, and height. The formula for the volume of a rectangular prism is V = l x w x h, where V is the volume, l is the length, w is the width, and h is the height.

Given;

Height of the conical part, h=12cm

Radius of the conical part, r=5cm

Height of the cylindrical part, H=2.5cm

Total volume of award=Volume of conical part+ Volume of cylindrical part

=πr²h/3+πr²H

=π×5²×12/3+π×5²×2.5

=314+196.25

=510.25cm²

Hence, volume of the award is 510.25 square centimeter.

The domain and range of this square root function y = 5/2√(-5x + 1) - 87 are as follows;

Domain = {x|x ≤ 1/5}.

Range = {y|y ≥ -87}.

The domain and range of this square root function y = -315√(11x - 3) - 15/88 are as follows;

Domain = {x|x ≥ 3/11}.

Range = {y|y ≤ -15/88}.

What is a domain?

In Mathematics and Geometry, a domain refers to the set of all real numbers for which a particular function is defined.

Additionally, the vertical extent of any graph of a function represents all range values and they are always read and written from smaller to larger numerical values, and from the bottom of the graph to the top.

By critically observing the graph shown in the image attached below for the given square root function y = 5/2√(-5x + 1) - 87 and y = -315√(11x - 3) - 15/88, we can reasonably and logically deduce the following domain and range:

Domain = {-∞, 1/5} or {x|x ≤ 1/5}.

Range = {-87, ∞} or {y|y ≥ -87}.

Domain = {3/11, ∞} or {x|x ≥ 3/11}.

Range = {-∞, -15/88} or {y|y ≤ -15/88}.
