Answer:

Triangle ABC is congruent to triangle DFE.

Step-by-step explanation:

the standard form for a quadratic function is

y = ax² + bx + c

our parabola had the equation

y = a(x - 2)² + q

let's do the "math" :

y = a(x² - 4x + 4) + q = ax² - 4ax + 4a + q

so, we know (when comparing with the standard form)

b = -4a

c = 4a + q

for the vertex we need to find the axis of symmetry first by using the standard formula

x = -b/2a

which is in our case

x = -(-4a)/2a = 4a/2a = 2

to get y for this x we need to find a and q first.

we are using the given points for that :

5 = a(-2)² - 4a×(-2) + 4a + q

-1 = a(4)² - 4a×4 + 4a + q

the first equation then forms into

5 = 4a + 8a + 4a + q = 16a + q

the second equation forms into

-1 = 16a - 16a + 4a + q = 4a + q

let's subtract the second from the first equation

5 = 16a + q

- -1 = 4a + q

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

6 = 12a + 0

12a = 6

a = 1/2

-1 = 4a + q = 4×1/2 + q = 2 + q

q = -3

so, the original equation for our parabola is

y = 1/2 × (x - 2)² - 3

so y for the vertex (remember, x = 2) is

y = 1/2 × (2 - 2)² - 3 = 1/2 × 0 - 3 = -3

so the vertex is (2, -3)

The p-value is 0.01, which means that it is very rare to observe a test statistic that is equal to or more extreme than the one that was actually observed. SO the option a is correct.

In the given question, in a hypothesis test for population proportion, we calculated the p-value is 0.01 for the test statistic, we have to find which statement of the p-value is correct.

The p-value is the probability of obtaining results as extreme as, or more extreme than, the observed results of a statistical hypothesis test, assuming that the null hypothesis is true. A small p-value (typically ≤ 0.05) indicates strong evidence against the null hypothesis, so you reject the null hypothesis.

A large p-value (> 0.05) indicates weak evidence against the null hypothesis, so you fail to reject the null hypothesis.

If the null hypothesis is correct, the p-value is the likelihood that a test statistic will be equal to or more extreme than the one that was actually observed. Given that the null hypothesis is correct in this situation, the p-value of 0.01 indicates that it is extremely unusual to see a test statistic as dramatic as the one that was actually seen. This shows that the alternative hypothesis is more likely to be correct and that the null hypothesis is probably not true.

Step-by-step explanation:

Hello there. To solve this question, we'll have to remember some properties about trigonometric functions and the right triangle.

We want to find x such that:

We'll use the second right triangle to show what we want.

First, given a triangle:

We know that the hypotenuse will be:

But most importantly, the tangent of the angles α and β can be calculated by only using the legs of the triangle: it is the ratio between the opposite side and the adjacent side to an angle.

and

Now look at the triangle we have:

We can easily check that:

So it would be good to find something that relates the ratio between those two numbers: the tangent of 60º!!

Below are some authorial techniques that can be used to create mystery, tension, or surprise in literature.

Order of events: The order in which events are presented can create a sense of mystery or suspense.

Pacing: The pace of a story can also be used to create suspense. A slow-paced story can build tension by allowing the reader to dwell on the details of a situation, while a fast-paced story can create excitement and surprise by keeping the reader guessing what will happen next.

Structure: The structure of a story can also be used to create mystery, tension, or surprise. For example, a story that is told in flashback can create a sense of mystery by revealing information about the past that is relevant to the present.

Time manipulation: The manipulation of time can also be used to create suspense.

Language: The language that an author uses can also be used to create mystery, tension, or surprise. For example, an author might use vague or ambiguous language to create a sense of mystery, or use strong language to create a sense of tension or surprise.

Answer:

y = 0

Step-by-step explanation:

When a question says find the horizontal line through certain points all you need to do is take the 2nd point which is 0 and make y equal to that. Doing that covers all x possibilities which means -1 is included and since you made y = 0 it passes through 0 as well.

There are approximately 2425 of those intervals that will contain the population means.

A confidence interval is a range of values that includes a parameter estimate with a certain degree of certainty. A confidence interval is a measure of uncertainty about an estimation procedure, rather than a statement about a parameter. A confidence interval is a specific value or a range of values in statistics that is used to estimate population characteristics.

This is because a 97% confidence interval means that if we were to repeat the sampling process many times, about 97% of the resulting intervals would contain the population mean. In other words, we would expect 97% of the intervals to be "correct" in the long run, while about 3% of them would not contain the population mean.

Therefore, out of the 2500 intervals we compute, we would expect approximately 0.97 x 2500 = 2425 intervals to contain the population mean, and about 0.03 x 2500 = 75 intervals not to contain the population mean. However, it's important to note that the actual number of intervals that contain the population means may vary from this expected value due to random sampling variability.

Where, \(\[\bar{x}\]\) is the sample mean

\(\[\frac{s}{\sqrt{n}}\]\) is the standard error of the mean

zα/2 is the z-score that covers α/2 in the tails of a normal distribution.

As we draw 2500 samples of size 100 from a population and compute a 97% confidence interval for each sample, the proportion of the sample will contain the population means.

Therefore, the number of intervals that will contain the population mean is approximately 2425.

Lowest score earned to be qualified for an interview is 92.82

X : Marks scored in interview

X ~ N(80,100)

Here we need to find x such that P(X > x) = 0.10

using standard normal table,

we get P( z > 1.282) = 0.10

It's always easy to use Standard normal distribution to solve questions of normal distribution because standard normal is special case of normal distribution with mean 0 and standard deviation 1.

To convert x (which follows Normal distribution) to standard normal use: \(\frac{x-\mu}{\sigma} \sim N(0,1)\)

so, \(z = 1.282 = \frac{x-\mu}{\sigma}\)

hence,

\(x = 1.282 * \sigma + \mu \\x = 1.282 * 10+_80 \\x = 92.82 \\\)

Step-by-step explanation:

Let the smallest even number = x

The next even number is x + 2, and the next is x + 4, and the next is x + 6, and the next is x + 8, and the next is x + 10

So the six numbers are: x, x + 2, x + 4, x + 6, x + 8, x + 10

The sum of all these numbers = 282

Solve:

6x + 30 = 282

6x = 252

x = 42

Now, the largest integer is x + 10, or in this case, it is 42 + 10 = 52

Based on the information provided, here are my responses to your questions:1. To prepare a budgeted income statement for the computer furniture segment for the quarter that ended June 30, 2022, we need to use the following information:

- Budgeted sales: 174 desks x $1,150 per desk = $199,800
                123 chairs x $450 per chair = $55,350
                                   Total = $255,150
- Cost of goods sold: (174 desks x $800 per desk) + (123 chairs x $275 per chair) = $197,775
- Gross profit: $255,150 - $197,775 = $57,375
- Advertising expenses: $14,160
- Other expenses: (assume they remain the same as before) $21,000
- Net income: $57,375 - $14,160 - $21,000 = $22,215

Therefore, the budgeted income statement for the computer furniture segment for the quarter ended June 30, 2022 would look like this:

Income Statement (Budgeted)
For the Quarter Ended June 30, 2022
Computer Furniture Segment

Sales                     $255,150
Cost of goods sold    ($197,775)
Gross profit              $57,375
Advertising expenses ($14,160)
Other expenses         ($21,000)
Net income               $22,215

2. Based on the budgeted income statement, the proposed changes would increase the budgeted net income for the quarter by $4,215 ($22,215 - $18,000). This is because the increase in sales revenue ($255,150 vs. $216,000 before) is greater than the increase in advertising expenses ($14,160 vs. $9,000 before), which leads to a higher gross profit and net income.


1. To prepare a budgeted income statement for the computer furniture segment for the quarter that ended June 30, 2022, with the proposed changes, follow these steps:

a. Calculate the total sales revenue for desks and chairs:
  Desks: 174 units × $1,150 = $200,100
  Chairs: 123 units × $450 = $55,350
  Total sales revenue: $200,100 + $55,350 = $255,450

b. Calculate the total advertising expenses:
  Advertising expenses: $14,160

c. Compute the total expenses:
  Total expenses = Product costs per unit (desks + chairs) + Advertising expenses + Other expenses

  *Note: Since the product costs per unit and other expenses are not provided, you'll need to fill in these values to compute the total expenses.

d. Calculate the budgeted net income:
  Budgeted net income = Total sales revenue - Total expenses

2. To determine if the proposed changes increase or decrease the budgeted net income for the quarter, compare the budgeted net income from the original plan to the budgeted net income with the proposed changes. If the new budgeted net income is higher than the original, the proposed changes increase the net income; if it's lower, the changes decrease the net income.

Step-by-step explanation:

The volume for a cube is

V = s * s * s or s^3

s = 8

V = 8 * 8 * 8

V = 512 cubic inches.

There are two possible volumes for the rectangular prism: 36 cubic units or 25 cubic units.

To find the volume of the rectangular prism with a space diagonal of 13 units and integer unit dimensions, we can follow these steps:

1. Recall that the space diagonal of a rectangular prism can be found using the Pythagorean theorem in 3D: d² = l² + w² + h², where d is the space diagonal, and l, w, and h are the length, width, and height of the prism.

2. Given that the space diagonal is 13 units, we have: 13² = l² + w² + h².

3. Since the dimensions are integers, we need to find the combination of l, w, and h that satisfies this equation. Possible combinations are: (2, 3, 6) and (1, 5, 5), as these are the only sets of integers that satisfy the equation.

4. Now, we can calculate the volume of the rectangular prism using the formula: Volume = l × w × h.

For the combination (2, 3, 6), the volume is: 2 × 3 × 6 = 36 cubic units.
For the combination (1, 5, 5), the volume is: 1 × 5 × 5 = 25 cubic units.

So, there are two possible volumes for the rectangular prism: 36 cubic units or 25 cubic units.
