Let's call the repeating decimal x, so x = -0.433333...

We can write this as:

10x = -4.33333...

And if we subtract x from 10x, we get:

10x - x = 9x = -4

So, x = -4/9.

Therefore, the decimal -0.43 (the 3 is repeating) as a fraction in simplest form is -4/9.

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.

In conclusion, while the data collected for the Denver Broncos players provides useful information about that specific team, it is not sufficient to draw conclusions about the mean salary of players in the entire NFL without obtaining a representative sample from all teams.

To represent 1 2/3 on a number line, we start by locating the integer 1 on the number line:

----|-----------|-----------|-----------|-----------|-----------|

 -3           -2          -1            0           1            2

Next, we need to locate the fractional part 2/3 of a unit. To do this, we divide the interval between 1 and 2 into three equal parts, and then shade two of those parts:

----|-----------|-----------|-----------|-----------|-----------|

 -3          -2          -1            0            1            2

The value of k, or the degrees of freedom for this hypothesis test, is 6.

The value of k in this scenario would depend on the number of categories or levels for each of the variables being tested. Since the first question has three possible answers (ticket office, platform machine, online), and the second question has four possible answers (very happy, happy, neutral, unhappy), the degrees of freedom would be (3-1) x (4-1) = 6. Therefore, the chi-square distribution used in the hypothesis test would have 6 degrees of freedom.
To find the value of k, we need to determine the degrees of freedom for this chi-square test. The formula for calculating degrees of freedom in a chi-square test is:

k = (number of rows - 1) x (number of columns - 1)

In this case, the number of rows corresponds to the method of payment (ticket office, machine on the platform, or online), which gives us 3 rows. The number of columns corresponds to the levels of happiness (very happy, happy, neutral, or unhappy), which gives us 4 columns.

Using the formula:

k = (3 - 1) x (4 - 1)
k = 2 x 3
k = 6

The value of k, or the degrees of freedom for this hypothesis test, is 6.

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.

Answer:

See below

Step-by-step explanation:

11. This is a tangent-chord angle, which means the angle is half of the measure of its intercepted arc.

7x - 10 = (1/2) * 120

7x - 10 = 60

7x = 70

x = 10

12. This is a chord-chord angle, which means the angle is half of the sum of the measures of the arcs intercepted by the chord-chord angle and its vertical angle.

26x - 2 = (1/2) * (131 + 18x + 1)

26x - 2 = (1/2) * (18x + 132)

26x - 2 = 9x + 66

17x = 68

x = 4

13. This is a secant-tangent angle, which means the angle is half of the difference between the measures of the intercepted arcs.

5x - 5 = (1/2) * (190 - (13x - 7))

5x - 5 = (1/2) * (197 - 13x)

10x - 10 = 197 - 13x

23x = 207

x = 9

14. This is also a secant-tangent angle.

2x + 14 = (1/2) * (6 + 14x - 58)

2x + 14 = (1/2) * (14x - 52)

Step-by-step explanation:

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.

Therefore, option C is the correct answer.

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.

The complete question is:-

total number of chips = 7 + 9 + 3 + 6

total number of chips = 25

yellow chips = 3

blue chips = 6

probability of drawing a yellow chip = 3/25

probability of drawing a blue without replacing the first yellow drawn = 6/24

probability of drawing a yellow without replacement and then a blue = 3/25 × 6/24

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.

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
