We can see that there are 9 possible outcomes for spinning the spinner two times.

By pairing each potential result for the first spin with each potential result for the second spin, we can list all the outcomes and establish the sample space for spinning the spinner twice. Since there are three possible results for each spin, spinning the spinner twice has a total of 3 x 3 = 9 outcomes.

Making a table that displays every scenario is one technique to list the sample space:

Spin 1 Spin 2

Blue  Blue

Blue Orange

Blue  Red

Red          Blue

Red   Orange

Red          Red

Orange  Blue

Listing all the potential pairs of outcomes is another way to list the sample space:

Blue, Blue, Blue, Orange, Blue, Red, Red, Blue, Orange, Red, and Orange, Red; Blue, Blue, Blue, Orange, Blue, Red; and Orange, Blue, Orange, Orange, Red

In either case, we can see that spinning the spinner twice can result in 9 different results.

What is a bar graph?

A bar graph, also called a bar chart, is a kind of data visualization that uses rectangular bars to represent data. Each bar's height or length corresponds to the value it stands for. Bar graphs are frequently used to compare and present various data sets or to demonstrate how data has changed over time.

The vertical axis (y-axis) in a conventional bar graph indicates the values or quantities being measured, while the horizontal axis (x-axis) represents the categories or variables being compared. Each bar in the graph represents a separate category or variable, and they are arranged along the x-axis. Each bar's height or length denotes the value or amount related to that category or variable.

Depending on the volume and complexity of the data being presented, bar graphs can be simple or complex. They can be applied to emphasize patterns or trends in the data, demonstrate changes over time, or compare data across several groups or categories. Among the many disciplines that employ bar graphs for data analysis are business, economics, social sciences, and natural sciences.

Based on the given graph, it appears that Patrick is responsible for choosing the company his local community will use for waste disposal. The graph shows the percentage of residents who prefer each of the four companies, labeled A, B, C, and D.

Answers

The length of AD is 3 units.

How can we solve?

We begin from the equation:

| ² + (AD)² = (2x)²

An equation is described as a formula that expresses the equality of two expressions, by connecting them with the equals sign.

Next step we take is simplifying the right-hand side by squaring 2x:

| ² + (AD)² = 4x²

Substituting x=√3, we get:

| ² + (AD)² = 4(√3)²

| ² + (AD)² = 4(3)

| ² + (AD)² = 12

(AD)² = 12 - ²

(AD)² = 12 - 3

(AD)² = 9

AD = √9

AD = 3 units

Therefore, the length of AD is 3 units.

Graph the function f(x)=1/2(2)^x on the coordinate plane.

Answers

The graph of [tex]f(x)=\frac{1}{2}(2^{x} )[/tex] on the coordinate plane is shown below.

Define a graph?

A graph is a visual representation of a set of objects, typically represented as points or nodes, and the relationships between them, typically represented as lines or edges.

To graph the function [tex]f(x)=\frac{1}{2}(2^{x} )[/tex] on the coordinate plane, we can follow these steps:

Choose a range of x-values to plot. For this function, we can choose a range of x-values from -3 to 3.Calculate the corresponding y-values for each x-value. To do this, we can substitute each x-value into the equation [tex]f(x)=\frac{1}{2}(2^{x} )[/tex] and simplify. If x = 0, we get [tex]f(0)=\frac{1}{2}(2^{0} )[/tex] = 1/2. Similarly, If x = 1, we get [tex]f(1)=\frac{1}{2}(2^{1} )[/tex] = 1, and when x = -1, we have [tex]f(-1)=\frac{1}{2}(2^{-1} )[/tex] = 1/4.Plot the points (x, y) for each x-value and its corresponding y-value. For example, the point (0, 1/2) corresponds to the x-value 0 and y-value 1/2.

Connect the points with a smooth curve to form the graph of the function.

The graph of [tex]f(x)=\frac{1}{2}(2^{x} )[/tex] on the coordinate plane is shown below.

Note that the graph of the function is an exponential curve that passes through the point (0, 1/2) and approaches the x-axis as x approaches negative infinity. As x approaches positive infinity, the function increases without bound.

Step-by-step explanation:

what are the zeros of the function f(x)=(x^2-13x+40)(x^2-2x+3)

Answers

Step-by-step explanation:

To find the zeros of the function f(x), we need to find the values of x that make f(x) equal to zero.

f(x) = (x^2 - 13x + 40)(x^2 - 2x + 3)

Setting f(x) equal to zero, we can use the zero product property to solve for x:

(x^2 - 13x + 40)(x^2 - 2x + 3) = 0

Either (x^2 - 13x + 40) = 0 or (x^2 - 2x + 3) = 0.

Solving for the first equation, we can use the quadratic formula:

x = [13 ± √(13^2 - 4(1)(40))] / 2(1)

x = [13 ± √(169 - 160)] / 2

x = [13 ± √9] / 2

So, the solutions for the first quadratic equation are x = 8 and x = 5.

Solving for the second equation, we can again use the quadratic formula:

x = [2 ± √(2^2 - 4(1)(3))] / 2(1)

x = [2 ± √4] / 2

So, the solutions for the second quadratic equation are x = 1 and x = 2.

Therefore, the zeros of the function f(x) are x = 8, x = 5, x = 1, and x = 2.

Imagine the country is made up of 100 households. The federal government needs to collect $800,000 in income taxes to be able to function. The population consists of 6 groups: Group A: 20 households that earn $12,000 each Group B: 20 households that earn $29,000 each Group C: 20 households that earn $50,000 each Group D: 20 households that earn $79,000 each Group E: 15 households that earn $129,000 each Group F: 5 households that earn $295,000 each This scenario is roughly proportional to the actual United States population and tax needs. We are going to determine new income tax rates. The first proposal we’ll consider is a flat tax – one where every income group is taxed at the same percentage tax rate. 1) Determine the total income for the population (all 100 people together)

Answers

The total income for the 100 households in the country, where the federal government needs to collect $800,000 in income taxes, is $6,810,000.

How is the total income determined?

The total number for the 100 households is computed using the mathematical operations of multiplication and addition.

Multiplication operation involves multiplying the number of households in each group by the income earned by the group.

Addition operation involves summing the groups' household total income.

The population of the imagined country = 100 households

The expected revenue in income taxes = $800,000

The number of groups in the population = 6

Group    Number of Households    Income       Total Income

Group A                    20                  $12,000        $240,000 (20 x $12,000)

Group B                    20                 $29,000        $580,000 (20 x $29,000)

Group C                    20                 $50,000     $1,000,000 (20 x $50,000)

Group D                    20                 $79,000     $1,580,000 (20 x $79,000)

Group E                     15                $129,000     $1,935,000 (15 x $129,000)

Group F                      5               $295,000     $1,475,000 (5 x $295,000)

Total income =       100                                     $6,810,000

Thus, using mathematical operations, the total income for the 6 groups of 100 households in the country is $6,810,000.

What is scientific notation?

Scientific notation is a way of expressing a number as a number between 1 and to multiplied by a power of 10.

We can perform the subtraction in the usual way, using the fact that the numbers are already in scientific notation:

(8.4 × 10³) − (6.4 × 10²) = 8.4 × 1000 − 6.4 × 100

= 8400 − 640

Calculate (a) the weight of each type of coffee in 800 g of X: (b) the weights of type P coffee and type R coffee in 800 g of Y: (c) the ratio of the three types of coffee in a third standard blend Z. formed by mixing equal weights of X and Y: (d) the weight of type P coffee in 800 g of Z.​

Answers

If two types of coffee. P and Q. are blended in the ratio 3: 13 by weight to form a standard blend X. The weight of type P coffee in 800g of X is 3x = 150g, and the weight of type Q coffee is 13x = 650g.

How to find the  weight of type P coffee?

(a) Let the weight of P coffee in 3 parts of X be 3x, and the weight of Q coffee in 13 parts of X be 13x. Then, the total weight of X is 16x.

We know that the ratio of P to Q coffee in X is 3:13, so the total weight of P coffee in X is 3x, and the total weight of Q coffee in X is 13x. Therefore, the weight of each type of coffee in 800 g of X is:

P coffee = (3/16) * 800 g = 150 g

Q coffee = (13/16) * 800 g = 650 g

(b) Let the weight of P coffee in blend Y be x, the weight of Q coffee be 7x, and the weight of R coffee be 12x.

We know that the ratio of P to Q to R coffee in Y is 1:7:12, so the total weight of P coffee in Y is x, the total weight of Q coffee in Y is 7x, and the total weight of R coffee in Y is 12x. Therefore, the weights of type P coffee and type R coffee in 800 g of Y are:

P coffee = (1/20) * 800 g = 40 g

R coffee = (12/20) * 800 g = 480 g

(c) To form blend Z, we mix equal weights of X and Y. Therefore, the total weight of Z is 800 g + 800 g = 1600 g.

The weight of P coffee in Z is (150 g + 40 g)/2 = 95 g.

The weight of Q coffee in Z is (650 g + 7/20 * 800 g)/2 = 465 g.

The weight of R coffee in Z is (12/20 * 800 g + 480 g)/2 = 480 g.

Therefore, the ratio of P to Q to R coffee in blend Z is 95: 465: 480.

(d) The weight of P coffee in 800 g of Z is (19/324) * 800 g = 47 g.

Describe what [tex]P(x) = x^4 - x^3 - 11x^2 + 9x + 18[/tex]. the graph looks like and, in general, how to sketch the graph without using technology. Use complete sentences, and focus on the end behaviours of the graph and where the company will break even (where P(x) = 0)

Answers

Answer:

Step-by-step explanation:

To sketch the graph of the polynomial function P(x) = x^4 - x^3 - 11x^2 + 9x + 18 without using technology, we can follow the following steps:

1. Determine the end behaviors of the graph: As x approaches negative infinity, the dominant term of the polynomial is x^4, which is positive. As x approaches positive infinity, the dominant term of the polynomial is also x^4, which is positive. Therefore, the end behaviors of the graph are both upward, which means that the graph rises to positive infinity on both ends.

2. Find the x-intercepts: To find the x-intercepts, we need to solve the equation P(x) = 0. One way to do this is to use synthetic division or long division to factor the polynomial. However, since the degree of the polynomial is 4, it may be difficult to find the roots algebraically. Alternatively, we can use technology or a graphing calculator to find the approximate values of the x-intercepts. Using a graphing calculator, we find that the x-intercepts are approximately -2.23, -0.43, 1.19, and 3.47.

3. Find the y-intercept: To find the y-intercept, we can set x = 0 in the equation P(x) = x^4 - x^3 - 11x^2 + 9x + 18, which gives P(0) = 18. Therefore, the y-intercept is (0, 18).

4. Determine the location of the minimum point: To find the location of the minimum point, we can use calculus and take the derivative of P(x) with respect to x. Setting the derivative equal to zero and solving for x, we find that x = -0.5 or x = 1. Therefore, the minimum point occurs at either (-0.5, P(-0.5)) or (1, P(1)). Using a graphing calculator, we find that the minimum value of P(x) is approximately -8.09, which occurs at x = -0.5.

Based on these steps, we can sketch the graph of P(x) as follows:

* The end behaviors of the graph are both upward.

* The x-intercepts are approximately -2.23, -0.43, 1.19, and 3.47.

* The y-intercept is (0, 18).

* The minimum point occurs at approximately (-0.5, -8.09).

* The graph is symmetric about the vertical line x = 0, since P(-x) = P(x) for all x.

5. To find where the company will break even, we need to find the values of x such that P(x) = 0. Using a graphing calculator or technology, we find that the company will break even at approximately x = -2.23, -0.43, 1.19, and 3.47. These correspond to the x-intercepts of the graph. Therefore, the company will break even at these values of x.



What is w, m, and n? please show your work and/or explain

Answers

Answer:

w = 102

m = 78

n = 58

Step-by-step explanation:

∠m is an exterior angle of the triangle on the left

exterior angle = sum of alternate interior angles

m° = 36° + 42°

m  = 78

m and w are supplementary angles

m + w = 180

78 + w = 180

w = 180 - 78

w = 102

w is an exterior angle of the triangle on the right

w = n + 44

102 = n + 44

102-44 = n

n = 58

Here is some information about the cost of stickers in two shops.

Stickers4u
Pack of 25 stickers for £2.25

World Stationery
Pack of 10 stickers for £1.75
Buy 1 pack get 1 pack free

Gigi wants to buy the stickers for the best possible price.

Which shop should Gigi buy the 100 stickers from?
You must show how you get your answer.

Answers

(WORLD STATIONARY)

this is as 100÷25=4 so 2.25×4=£9

but

10×2=20 as buy 1 get 1 free

so

100÷20=5

1.75×5=£8.75

so it's cheaper

The scatter plot shows negative correlation because as the plotted value of x increases, the values of y generally decreases.

How to construct and plot the data in a scatter plot?

In this scenario, the x-values would be plotted on the x-axis (x-coordinate) of the scatter plot while the y-values would be plotted on the y-axis (y-coordinate) of the scatter plot through the use of Microsoft Excel.

From the scatter plot (see attachment) which models the relationship between the x-values and y-values, a linear equation for the line of best fit is given by

y = -0.441x + 6.085

In conclusion, we can reasonably infer and logically deduce that the scatter plot most likely indicates an inverse relationship between the x-values and y-values.

2/3 mile in 1/4 hour how many miles in one hour

Answers

Answer:

8/3

Step-by-step explanation:

To find how many miles are in one hour, we need to scale up the distance covered in 1/4 hour to the distance covered in 1 hour.

We can start by finding the distance covered in 1 hour:

2/3 mile in 1/4 hour = (2/3) ÷ (1/4) = 8/3 miles in 1 hour

Therefore, the ball covers 8/3 miles in one hour.

Answer:

8/3 miles an hour

Step-by-step explanation:

Because you can travel 2/3 in 1/4 (or 0.25) of an hour, that means you can travel 4 times that distance in 1 hour, assuming the velocity is constant.

To find this then, we simply multiply 2/3 by 4  (2/3*4/1) to get our final answer of 8/3 miles an hour.

For the new height requirements, this branch of the military requires women's heights to be at least 2.52 in and at most 6.96in.

How to get the z scores?

If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.

If we have

[tex]X \sim N(\mu, \sigma)[/tex]

(X is following normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex]  )

then it can be converted to standard normal distribution as

[tex]Z = \dfrac{X - \mu}{\sigma}, \\\\Z \sim N(0,1)[/tex]

(Know the fact that in continuous distribution, probability of a single point is 0, so we can write

[tex]P(Z \leq z) = P(Z < z) )[/tex]

Also, know that if we look for Z = z in z tables, the p value we get is

[tex]P(Z \leq z) = \rm p \: value[/tex]

We are given that;

Mean= 63.8 in

Standard deviation= 2.3 in

Requirement of women height= 58in - 80in.

Now,

To find the minimum and maximum height requirements for this branch of the military, we need to use the standard normal distribution formula, which converts any normal distribution to a standard normal distribution with a mean of 0 and a standard deviation of 1.

We can find the z-scores for the minimum and maximum heights as follows:

For the minimum height requirement:

z = (58 - 63.8) / 2.3 = -2.52

For the maximum height requirement:

z = (80 - 63.8) / 2.3 = 6.96

Using a standard normal distribution table or calculator, we can find the corresponding probabilities for these z-scores:

For a z-score of -2.52, the probability is 0.0059 or 0.59%

For a z-score of 6.96, the probability is very close to 1, or 100%

Therefore, the new height requirements for this branch of the military are:

At least 58 inches, which corresponds to a z-score of -2.52

At most 80 inches, which corresponds to a z-score of 6.96
