Mark me the brainliest

Step-by-step explanation:

Okay, let's break this down step-by-step:

The top figure represents the original vector: (7, -2)

To translate it to the bottom figure: (6, -4)

We need to determine the component form of the translation.

The x-component is 7 - 6 = 1  (it decreased by 1)

The y-component is -2 - (-4) = -2  (it decreased by 2)

Therefore, the component form of the translation is:  (1, -2)

So the translation vector that transforms the top figure (7, -2) into the bottom figure (6, -4) is (1, -2).

Does this make sense? Let me know if you have any other questions!

A. Greater than its adjacent interior angle. The measure of an exterior angle of a triangle is always C. greater than either remote interior angle.

An exterior angle is formed by extending one side of a triangle. In a triangle, the exterior angle is equal to the sum of the two remote interior angles (the two angles that are not adjacent to the exterior angle).

Therefore, the exterior angle will always be greater than either one of the remote interior angles.

The exterior angle theorem states that when two sides of a triangle are adjacent, the resulting exterior angle is equal to the sum of the degrees of the two interior angles of the triangle. This theorem can be used to find the measure of an unknown angle in a triangle.

The correct answer is option d) both 'a' and 'c'. The Sharpe ratio and Fama's net selectivity are performance evaluation measures that take into account unsystematic risk along with systematic risk.

The Sharpe ratio measures the excess return of a portfolio over the risk-free rate per unit of total risk (i.e., both systematic and unsystematic risk) and is given by:

Sharpe Ratio = (Portfolio Return - Risk-Free Rate) / Portfolio Standard Deviation

Fama's net selectivity, on the other hand, measures a portfolio's ability to generate returns over and above what would be expected based on its exposure to different factors (i.e., systematic risk) and its level of unsystematic risk. It is calculated as the difference between the portfolio's actual return and the return predicted by a multifactor model that takes into account the portfolio's exposure to different factors. Both of these measures account for unsystematic risk along with systematic risk, making them useful for evaluating portfolio performance. The Treynor ratio, on the other hand, only takes into account systematic risk and not unsystematic risk.

1. Choose a significance level (e.g., 0.05 or 0.10).
2. Perform a statistical test (e.g., t-test or ANOVA) to compare the mean weight gains of the two groups of babies.
3. Compare the p-value obtained from the test to the chosen level of significance.

Based on the information provided, we do not have the output or data necessary to determine whether to reject the null hypothesis or not. However, we can interpret the terms "hypothesis," "level," and "significance" in this context.

- Hypothesis: The president of Baby Organics Inc. has made a claim that her company's product is superior to her competitors because babies gain weight faster with her product. This is the alternative hypothesis, which is being tested against the null hypothesis that there is no difference in weight gain between babies fed Babyorganics and those fed the competitor's baby food.

Null Hypothesis (H0): There is no difference in weight gain between babies fed Babyorganics and those fed the competitor's food.
Alternative Hypothesis (H1): Babies fed Baby organics gain weight faster than those fed the competitor's food.

- Level: The significance level is a threshold that is set to determine whether the results of the survey are statistically significant. This threshold is usually set at 0.05 or 0.10, indicating a 5% or 10% chance of rejecting the null hypothesis when it is actually true.

- Significance: If the results of the survey are statistically significant at the chosen level of significance, it means that the observed difference in weight gain between babies fed Baby Organics and those fed the competitor's baby food is unlikely to have occurred by chance alone and is therefore likely to be a real effect.
Make a decision based on the comparison:

- If the p-value is less than or equal to the level of significance, reject the null hypothesis, which means there is evidence to support the claim that Baby organics lead to faster weight gain.
- If the p-value is greater than the level of significance, do not reject the null hypothesis, which means there is insufficient evidence to support the claim.

In order to determine whether the president of Baby Organics Inc. can conclude that the competitor's food is not as good for increasing baby weight, we would need to see the actual data and results of the survey.

The sample size needed for the margin of error to be 2% while we are 95% confident is 9604.

Margin of error = 2%

Confidence interval = 95%

The formula to calculate the margin of error is,

MOE = z σ/√n

Here z is the test statistic, σ is the population standard deviation and n is the sample size.

For a normal distribution,

z value for 95% confidence interval = 1.96

Population standard deviation = 1

Substituting,

0.02 = 1.96 / √n

√n = 1.96 / 0.02

n = (1.96/0.02)² = 9604

The negative value requested (a. te) represents the lower end of the confidence interval minus the mean:
a. te = 6.639 - 7 ≈ -0.361 (rounded to 3 decimal places)

To calculate the 80% confidence interval for the mean sleep time, we'll use the following formula:

CI = mean ± (t * (standard deviation / √sample size))

Given:
- Mean time = 7 hours
- Standard deviation = 0.6 hour
- Sample size = 6 people

First, we need to find the t-value (t-score) for an 80% confidence interval and degrees of freedom (df) = sample size - 1 = 6 - 1 = 5. Using a t-distribution table or calculator, the t-value for a two-tailed test with 80% confidence (or 0.1 significance level) and df = 5 is approximately 1.476.

Now, plug in the values into the formula:

CI = 7 ± (1.476 * (0.6 / √6))

Calculate the margin of error:

Margin of error = 1.476 * (0.6 / √6) ≈ 0.361

So, the 80% confidence interval is:

Lower limit: 7 - 0.361 ≈ 6.639 hours
Upper limit: 7 + 0.361 ≈ 7.361 hours

In this PE class with 48 students, one group of 24 students decides to play volleyball, leaving 24 students who will be shooting baskets. The teacher then divides the remaining 24 students into as many groups of 5 as possible, which results in 4 groups. Each group will have 5 students, and one student will be left without a group.

In this scenario, there are 48 students in the PE class. One group of 24 students chooses to play volleyball, leaving 24 students (48 - 24 = 24) remaining. The teacher then divides the remaining students into as many groups of 5 as possible to shoot baskets.

To determine how many groups of 5 can be formed, we'll divide the remaining students by 5:
24 ÷ 5 = 4 (with a remainder of 4)

So, the teacher can create 4 groups of 5 students each for shooting baskets. This accounts for 20 students (4 groups x 5 students = 20).

Since there were 24 students remaining after the volleyball group, and 20 of those students have been assigned to basketball groups, we're left with 4 students (24 - 20 = 4) who will climb the rock wall.

Median, because Beach Town is skewed. Therefore, option C is the correct answer.

The correct answer is Median, because Beach Town is skewed. The mean is the average of the data and works best when the data is symmetric, or evenly distributed around the center. Since the data for Beach Town appears skewed, with more temperatures on the higher end of the range, the median is a better measure for determining which location typically has a cooler temperature.

The median is the middle value of the data, so it is not affected by outliers as much as the mean.

The best measure of center to determine which location typically has the cooler temperature would be the median. The median is the best measure of center to use when comparing data because it is not affected by outliers or extreme values. Since both Sunny Town and Beach Town are skewed, the median is the more appropriate measure of center to use when comparing the data.

The equation of parabola with with focus (1,4)and latus rectum of 4 is given as y=(x−1)2+4, hence option C is correct.

We know that the focus of the parabola is at (1, 4), and the latus rectum is 4 units long. The latus rectum is the line segment that passes through the focus and is perpendicular to the axis of symmetry. Its length is equal to 4 times the distance from the focus to the directrix. Since the latus rectum is 4 units long, the distance from the focus to the directrix is 1 unit.

Therefore, the directrix is the horizontal line y = 3, which is 1 unit below the focus. The axis of symmetry is the vertical line x = 1. The standard form of the equation of a parabola with vertex at the origin, axis of symmetry along the x-axis, and focus at (p, 0) is:

x² = 4py

In this case, the vertex is (1, 0) and the focus is (1, 4). Therefore, we can write,

x - 1 = 4p(y - 0)

x - 1 = 4py

We know that the distance from the focus to the vertex is p, which is 4 units in this case. Therefore, the equation of the parabola is,

(x - 1)² = 16y

Simplifying this equation, we get,

y = (1/16)(x - 1)²

Therefore, the answer is C. y = (x - 1)²/16.

A rectangular painting has a diagonal measure of 20 inches and an area of 192 square inches. Using the formula for the area of a rectangle and the Pythagorean theorem the length and width of the painting are 8 inches and 24 inches respectively.

To solve this question, we will use the given information: the area of the rectangle (192 square inches) and the diagonal length (20 inches), along with the formula for the area of a rectangle and the Pythagorean theorem.
Step 1: Recall the formula for the area of a rectangle:
Area = length × width
We know that the area of the painting is 192 square inches. So, we have:
192 = length × width
Step 2: Recall the Pythagorean theorem for a right triangle:
a² + b² = c²
In this case, a and b represent the length and width of the rectangle, and c represents the diagonal. We know that the diagonal is 20 inches. So, we have:
length² + width² = 20²
length² + width² = 400
Step 3: Solve the system of equations:
192 = length × width
400 = length² + width²
We will solve the first equation for length:
length = 192 ÷ width
Step 4: Substitute the expression for length in the second equation:
(192 ÷ width)² + width² = 400
Step 5: Solve the equation for width:
width² - 400 = -(192 ÷ width)²
width⁴ - 400width² + 192² = 0
Step 6: Factor the equation and solve for width:
(width² - 64)(width² - 576) = 0
Two possible values for width are 8 and 24.
Step 7: Find the corresponding lengths:
If width = 8, then length = 192 ÷ 8 = 24
If width = 24, then length = 192 ÷ 24 = 8
So, the length and width of the painting are 8 inches and 24 inches.

Answer:

Area = 50.24 cm^2

Circumference = 25.12 cm

Step-by-step explanation:

To calculate the area and circumference of a circle with a diameter of 8cm, you can follow these steps:

Recall that the diameter of a circle is the distance across the circle passing through its center. In this case, the diameter is given as 8cm.

Recall that the radius of a circle is half of its diameter. To find the radius, you can divide the diameter by 2:

radius = diameter/2

radius = 8cm/2

radius = 4cmTo calculate the area of a circle, use the formula:

area = πr^2

where π is the mathematical constant pi (approximately 3.14) and r is the radius.

Substituting the values we have:

area = 3.14 x (4cm)^2

area = 3.14 x 16cm^2

area = 50.24cm^2

Therefore, the area of the circle with diameter 8cm is 50.24 square centimeters.

To calculate the circumference of a circle, use the formula:

circumference = 2πr

where π is again the mathematical constant pi and r is the radius.

Substituting the values we have:

circumference = 2 x 3.14 x 4cm

circumference = 25.12cm

Therefore, the circumference of the circle with diameter 8cm is 25.12 centimeters.

Answer:

the area is about 50.26548

the circumference is about 25.13274

It's important to consider the terms "deviation," "players," and the context of the question. The mean and standard deviation of the salaries of players on the Denver Broncos have been recorded. You'd like to know if it's appropriate to use these methods to perform a hypothesis test about the mean salary of players in the National Football League (NFL).

In this case, it may not be appropriate to use the methods of this section to perform a hypothesis test about the mean salary of players in the NFL. The reason is, the data collected only represents the players on the Denver Broncos and not the entire population of NFL players. The standard deviation and mean of the Denver Broncos' salaries may not accurately represent the salary distribution of the entire league, as there might be variations among different teams.

To perform a hypothesis test about the mean salary of players in the NFL, it would be necessary to gather data from a representative sample of players across all teams in the league. This would allow for a more accurate estimation of the true mean salary and standard deviation within the entire population of NFL players.
