The analyst should use the alpha aesthetic. The alpha aesthetic makes some points on a plot more transparent than others to call out specific data points.

A set of points plotted on a horizontal and vertical axis is known as a scatter plot. Because they can demonstrate the degree of correlation, if any, between the values of observed quantities or phenomena, scatter plots are crucial in statistics (called variables). In an effort to demonstrate the degree to which one variable is influenced by another, scatter plots are used to plot data points on a horizontal and vertical axis. The values of the columns set on the X and Y axes determine the position of the marker that represents each row in the data table.

Answer:

vertex is (6, -11)

Step-by-step explanation:

Given equation
f(x) = x² - 12x + 25

is that of an upward-facing parabola(since the coefficient of x² is positive).

The vertex will be at a minimum and its x-coordinate can be found by finding the first derivative of f(x), setting it equal to zero and solving for x

f'(x) = d/dx(x² - 12x + 25)

= 2x - 12

f'(x) = 0 ==> 2x - 12 = 0

2x = 12

x = 6

Substitute x = 6 in f(x) to get

f(6) = 6² - 12(6) + 25

= 36 - 72 + 25

= -11

So the vertex is at (6, -11)

The answers to the questions involving trigonometry are: 90, BC/AB ÷ BC/AB = 1, g = 6.5, <I = 62 degrees, h= 13.8, 12.0, x = 6.8, x = 66.4, 160.6, The pole = 6.7

Trigonometric ratios are special measurements of a right triangle, defined as the ratios of the sides of a right-angled triangle.  There are three common trigonometric ratios: sine, cosine, and tangent

For page 3 question 3,

a) <A + <B = 90 since <C = right angle

b) SinA = BC/AB and CosB = BC/AB

The ratio of the two angles BC/AB ÷ BC/AB = 1

I notice that the ratio of sinA and cosB gives 1

b) The ratio of CosA and SinB will give

BC/AB ÷ BC/AB

= BC/AB * AB/BC = 1

For page 5 number 3

Tan28 = g/i

g/12.2 = tan28

cross multiplying to have

g = 12.2*tan28

g = 12.2 * 0.5317

g = 6.5

b) the angle I is given as 90-28 degrees

<I = 62 degrees

To find the side h we use the Pythagoras theorem

h² = (12.2)² + (6.5)²

h² = 148.84 +42.25

h²= 191.09

h=√191.09

h= 13.8

For page 6

1) Sin42 = x/18

x=18*sin42

x = 18*0.6691

x = 12.0

2) cos28 = 6/x

xcos28 = 6

x = 6/cos28

x [= 6/0.8829

x = 6.8

3)  Tan63 = x/34

x = 34*tan63

x= 34*1.9526

x = 66.4

4) Sin50 123/x

xsin50 = 123

x = 123/sin50

x = 123/0.7660

x =160.6

In a statistical inference method, you'll draw a conclusion in the end - you'll infer something - about the characteristics of what you're comparing.

Statistical inference is a process used in statistics to draw conclusions or make predictions about a population based on a sample. It involves using data from a sample to make inferences about the larger population from which the sample is drawn.

To perform statistical inference, you typically follow these steps:

1. Formulate a research question or hypothesis: Start by identifying what you want to investigate or test. For example, you might want to determine if there is a significant difference in test scores between students who receive tutoring and those who do not.

2. Collect data: Gather relevant data through surveys, experiments, or other methods. In the example above, you would collect test scores from both the tutoring and non-tutoring groups.

3. Choose an appropriate statistical inference method: There are various statistical inference methods available, such as hypothesis testing, confidence intervals, and regression analysis. Select the method that best suits your research question and data.

4. Analyze the data: Apply the chosen statistical inference method to the collected data. This involves performing calculations and statistical tests to draw conclusions about the population based on the sample.

5. Draw conclusions: Based on the results of the analysis, draw conclusions about the characteristics of the population you are studying. In our example, you might conclude that students who receive tutoring have significantly higher test scores than those who do not.

In summary, in a statistical inference method, you use data from a sample to draw conclusions or make predictions about the characteristics of a larger population. This process involves formulating a research question, collecting data, selecting an appropriate inference method, analyzing the data, and drawing conclusions based on the results.

Two equal-size vectors at right angles to each other have a resultant that is equal to \(\sqrt{2}\) times the magnitude of each individual vector.

The magnitude of the resultant vector of two equal-size vectors at right angles to each other can be determined using the Pythagorean theorem.

Let's assume the magnitude of each vector is represented by "a".

According to the Pythagorean theorem, the magnitude of the resultant vector, denoted as "R", can be calculated as:

R =\(\sqrt{a^2 + a^2}\)

R = (\(\sqrt{2a^{2} )}\)

R = \(\sqrt{2}\) a

Therefore, the magnitude of the resultant vector is equal to \(\sqrt{2}\) times the magnitude of each individual vector.

Answer:

8. The length of the longest side is 40 ⇒ H

Step-by-step explanation:

8. In the given figure

∵ The triangle has two equal sides 2x + 12 and 5x - 9

→ Equate their expressions to find the value of x

∴ 5x - 9 = 2x + 12

→ Add 9 to both sides

∵ 5x - 9 + 9 = 2x + 12 + 9

∴ 5x = 2x + 21

→ Subtract 2x from both sides

∵ 5x - 2x = 2x - 2x + 21

∴ 3x = 21

→ Divide both sides by 3 to find x

∵ \(\frac{3x}{3}\) = \(\frac{21}{3}\)

∴ x = 7

∵ The longest side is 6x - 2

→ Substitute the value of x in its expression to find its length

∴ The longest side = 6(7) - 2 = 42 - 2

∴ The longest side = 40

∴ The length of the longest side is 40

In Herrnstein's matching equation, the letters and numbers to the left of the equals sign refer to behaviour.

THE MATCHING LAW

Herrnstein's Experiment Herrnstein (1961) conducted an experiment with pigeons in a room with two response buttons, red and white. Each key was assigned its own VI gain schedule. For example, under one condition, the left button pick was boosted on a VI 135 second schedule, and the right button pick was boosted on a VI 270 second schedule.

After the birds have learned as much as possible about this electoral situation, how do they distribute their responses? We trained them for days and then measured their reactions. As is often the case with VI schedules, birds returned many responses for each reinforcer received. Most interesting, however, is that in this condition, where two-thirds of the reinforcers came from the left button, the birds performed about two-thirds of the responses with the left button. That is, the proportion of left button responses equaled or matched the proportion of reinforcers delivered by the left button. In another condition, two birds received only about 15% of reinforcers from the left key and responded about 15% to that key.

Based on these results, Herrnstein proposed the following general principle for individual behavior when presented with alternative sequences. So, what you think makes sense rather than other options available at that particular moment.

Valerie and 3 friends can paint a house in 6 hours. If Valerie and 6 friends paint, it would take approximately 3.43 hours.

The time it takes Valerie to paint her house varies inversely with the number of people. This means that as the number of people increases, the time it takes to paint the house decreases, and vice versa.
In this scenario, it takes Valerie and 3 of her friends a total of 6 hours to paint the house. We can set up an equation to represent the inverse variation relationship:
(time) = (constant) / (number of people)
Let's call the constant "k". Using the given information, we can write the equation as:
6 = k / 4
To find the value of k, we can multiply both sides of the equation by 4:
6 * 4 = k
k = 24
Now that we know the value of the constant, we can use it to answer the question. The question asks how long it would take for Valerie and 6 of her friends to paint the house. Let's call this unknown time "x". Using the same equation, we can write:
x = 24 / (6 + 1)
Simplifying the equation:
x = 24 / 7
x ≈ 3.43
Therefore, it would take approximately 3.43 hours for Valerie and 6 of her friends to paint the house.

The cost of the truck with 3 passengers is A = $ 45

Given data ,

Let's denote the number of passengers as P and the weight of the truck in pounds as W.

For the base rate of $30 per vehicle, the equation can be written as:

Cost = $30

For additional passengers beyond the first two, the equation can be written as:

Cost += ($5) * (P - 2)

For excess weight over 4,000 pounds, the equation can be written as:

Cost += ($10) * (W - 4000) / 500

To find the cost of a truck that weighs 5,000 pounds with three passengers, we substitute the values into the equation:

Cost = $30 + ($5) * (3 - 2) + ($10) * (5000 - 4000) / 500

Cost = $30 + $5 + $10

Cost = $45

Therefore, the sum of the first 1234 terms of this sequence is 1234.

To find the sum of the first 1234 terms of the sequence consisting of 1's separated by blocks of 2's with n 2's in the nth block, we need to determine the number of blocks and the number of 1's in each block.

Let's examine the pattern of the sequence:

Block 1: 2's

= 1's

= 1 (1 2)

Block 2: 2's

= 2's

= 22 (1 22 1)

Block 3: 2's

= 3's

= 222 (1 222 1)

Block 4: 2's

= 4's

= 2222 (1 2222 1)

...

We observe that the number of 2's in each block is equal to the number of the block itself. So, in the nth block, there are n 2's.

Now, let's calculate the number of blocks required to reach the 1234th term:

To find the number of blocks, we need to determine the maximum block number before the 1234th term. We can calculate this by finding the sum of the series 1 + 2 + 3 + ... + n until the sum is greater than or equal to 1234.

The formula for the sum of the series 1 + 2 + 3 + ... + n is given by: S = (n/2)(n+1).

Let's solve this equation:

(n/2)(n+1) = 1234

\(n^2 + n - 2468 = 0\)

Using the quadratic formula:

n = (-1 + √(1 + 4*2468)) / 2

n ≈ 61.76

Since n must be a whole number, we take the ceiling of n, which gives us 62.

Therefore, there are 62 blocks in the sequence.

Next, let's calculate the number of 1's in each block:

In the nth block, there are n 2's. Since each 2 is separated by a 1, there are n + 1 terms in each block.

So, the number of 1's in each block is (n + 1) - n = 1.

Since there is always one 1 between two consecutive blocks, the total number of 1's in the sequence is equal to the number of blocks, which is 62.

Finally, let's calculate the sum of the first 1234 terms:

Each block has n + 1 terms, which gives us (n + 1) + (n + 1) + ... + (n + 1) (62 times).

Sum of (n + 1) repeated 62 times = 62(n + 1)

= 62 * 2

= 124.

In addition to the blocks, we have 1234 - 62 = 1172 remaining terms, which are all 1's.

So, the sum of the first 1234 terms is 62 + 1172 = 1234.

Brainly doesn't provide online graphing tools, so I will try to walk you through what to do.

First put both equations in slope-intercept form:

y + x = 7  →  y = -x + 7

3y - 6x = 3   →   3y = 6x + 3  →  y = 2x + 1

These are easy to graph now.  

For equation (1), place a point on the y-intercept (0,7), then draw a line with a slope of -1  (down one, over one, down one, over one, etc.).  The x-intercept is (7,0).

For equation (2), the y-intercept is point (0,1).  Draw a line with a slope of 2 (up 2, over 1, up 2, over 1, etc.)  The x-intercept is (-1/2, 0).

Where the 2 lines intersect is the solution.  They should intersect at point (2,5).
