The 95% confidence interval for a population mean has a margin of error (E) of 41

The confidence interval for a population mean is given by:

Confidence interval = μ ± E = (μ - E, μ + E)

Where μ is the mean and E is the margin of error.

Since the confidence interval is (428, 510), hence:

μ - E = 428      (1)

μ + E =  510     (2)

Subtracting equation 1 from equation 2:

2E = 82

E = 41

μ - E = 428

μ -41 = 428

μ = 469

Hence the margin of error (E) is 41

B. Yes coin-operated machine larcenies unusual

C. Such incidents cannot be considered unusual events

A. The probability model for type of larceny theft is contained in the attachment we have here

B. An event is defined as unusual if the probability of it occurring is close to 0, meaning that it is less likely to happen. We typically consider events with a probability of 5%, or 0.05, as unusual. In the case of coin-operated machine larcenies, the calculated probability is 0.007.

This value is considerably less than 5% or 0.05 and is near to 0, indicating that this type of larceny is unlikely to happen. Thus, we can categorize coin-operated machine larcenies as an unusual event because their probability, P(Coin-Operated machine larceny), is less than 0.05.

C. The probability of larcenies from buildings is calculated to be 0.211. This value is significantly higher than 5%, or 0.05.

Thus, such incidents cannot be considered unusual events, since their probability, P(Building Larceny), is greater than 0.05. Consequently, the correct option would be Option A.

Answer:

The value of b is 4.

Step-by-step explanation:

First, find the y-intercept.

y = mx + b

-8 = -2(5) + b

-8 = -10 + b

2 = b

So now our equation is y = -2x + 2. Now plug in the values.

y = -2(-1) + 2

y = 4  

The solution to  the Cubic equation 5/(3b³ -2b² - 5) = 2/(b³ - 2) are b = 0 and b =4

Given Cubic equation is 5/(3b³ -2b² - 5) = 2/(b³ - 2)

5×(b³ - 2)=2×(3b³ -2b² - 5)

5b³  - 10 = 6b³ - 4b²  - 10

5b³  - 6b³ = - 4b²

-b³ = - 4b²

b³- 4b²= 0

b²(b - 4) = 0

b²= 0 and b - 4 = 0

So we  get b = 0 and b = 4

The solution to the Cubic equation 5/(3b3 -2b2 - 5) = 2/(b3 - 2) are b = 0 and b = 4.

The graph which represents the solution to given inequality -1/4(12x+8) <-2x+11  is option C. A straight line passing from minus 17 to minus 5, A ray with a red dot at minus 13, and it passes through minus 5

An inequality is an equation which compares two expressions where either one is greater than or less than or greater than equal to or less than equal to from another one.

To solve inequalities: we can add some number (positive or negative) to both sides of the without changing the inequality sign.

We can divide both sides by a positive number no change of  sign of inequality

We can divide both sides by a negative number but we have to change sign of inequality.

Given inequality is

-1/4(12x+8) <-2x+11  

⇒-3x -2 < -2x +11

Adding 2 both sides, we get

⇒ -3x < -2x +13

Adding 2x both sides , we get

⇒2x-3x < 2x-2x+13

⇒ -x < 13

Multiply both sides by (-1)

⇒ (-1)(-x)> -13 ( multiplied by negative number so sign is reversed)

⇒ x >-13

Therefore , the solution to given inequality is all real numbers greater than -13, thus answer is option C. A straight line passing from minus 17 to minus 5, A ray with a red dot at minus 13, and it passes through minus 5 ( as it has all number right to -13 included in the solution)

The null hypothesis for the data will be 21.62 and the alternate hypothesis is 2.02 for the p-value for the data is 0.2253 .

The charge at which anything happens is referred to as the velocity at which it happens.

The required details for mean rate :

(a) H0: µ = 21.62

Ha: µ ≠ 21.62

(b) t = -1.231

p-value = 0.2253

(c) Stop rejecting H0 right now. No longer significantly different from the domestic water tariff in Tulsa, the suggested household water charge per five CCF for the entire USA.

(d) H0: µ = 21.62

Ha: µ ≠ 21.62

t = -1.231

check statistic ≥ 2.020

Don't dismiss H0 any longer. The suggested five CCF residential water charge for the entirety of the USA is no longer significantly different from the five CCF residential water tariff in Tulsa.

The P-value is higher at 0.05, the level of significance. The impact in this instance is negligible. The attempt to reject the null hypothesis failed.

The conclusion is that there is insufficient statistical support to determine whether other American cities have a different mortality rate than Tulsa.

The crucial values for t at this level of significance are t=2.019.

Given that the statistic t = -1.15 is inside the acceptance range in this case, the null hypothesis is not disproved.

Answer:

P = 0.2517

Step-by-step explanation:

In this case we must calculate the probability of event, which would be the number of specific events (that is, at least one woman and the rest men, 4), then it would be to choose 1 of 6 women by 4 of 9 men divided by the number of total events, which would be to choose 5 (committee size) out of 15 (9 men + 6 women, total number of people)

P (at least one woman) = 6C1 * 9C4 / 15C5

we know that nCr = n! / (r! * (n-r)!)

replacing we have:

6C1 = 6! / (1! * (6-1)!) = 6

9C4 = 9! / (4! * (9-4)!) = 126

15C5 = 15! / (5! * (15-5)!) = 3003

Therefore it would be:

P (at least one woman) = 6 * 126/3003

P = 0.2517

That is, approximately 1 out of 4 women.

3x-1=3x+8

or -1 =8

which is impossible as -1≠8

so no solution.

Step-by-step explanation:

3x - 1=4x +8 - x

3x - 4x +x = 1 +8 (grouping method)

4x - 4x =9

0 =9

(impossible) : where it's impossible to 0 to be equal to number 9, right

So, there's no solution

The sum of three consecutive terms of an arithmetic sequence is 27, and the sum of their square is 293. What is the absolute difference between the greatest and the least of these three numbers in the arthritic sequence?

Let

x -----> first consecutive term

so

x+d ----> second consecutive term

x+2d ----> third consecutive term

where

d -----> common factor

we have that

x+(x+d)+(x+2d)=27

3x+3d=27------> simplify -----> x+d=9 -----> equation 1

the sum of their square is 293

so

x^2+(x+d)^2+(x+2d)^2=293

x^2+(x^2+2xd+d^2)+(x^2+4xd+d^2)=293 ---------> equation 2

Solve the system by graphing

the first term is 4

the second term is 4+5=9

the third term is 4+2(5)=14

When the relationship between the regression line and the data points is weak, it indicates a lack of strong association and highlights the need for further investigation and consideration of alternative explanations to better understand the underlying dynamics of the variables being studied.

When the relationship is weak, it implies that the data points are scattered and do not follow a clear pattern or trend. The variability in the data is high, making it difficult to establish a strong linear relationship. This could be due to various reasons, such as the presence of outliers, measurement errors, or the existence of other unaccounted factors influencing the variables.

The weak relationship between the regression line and the data points suggests that the predictive power of the regression model is limited. The regression line may not effectively explain or predict the values of the dependent variable based on the independent variable(s). Consequently, relying solely on the regression analysis to make accurate predictions or draw conclusions may be unreliable.

It is important to interpret the results cautiously and consider alternative explanations or additional variables that might contribute to the observed variability in the data. Further exploration and analysis may be needed to identify other potential factors that influence the relationship between the variables and to determine whether a different model or approach is more appropriate.

At this rate, the Boeing 747 airplane will fly approximately 1698.12 miles in 3 hours.

Distance traveled by a Boeing 747 in 3 hours: To determine the distance traveled by a Boeing 747 airplane in 3 hours, we can use the given information about its average speed and the time duration.

The average speed of the Boeing 747 airplane is calculated by dividing the total distance traveled by the time taken. In this case, the airplane flies 3,000 miles across the United States in 5.3 hours. Therefore, we can determine its average speed as follows:

Average speed = Total distance / Time taken

Average speed = 3,000 miles / 5.3 hours

Average speed ≈ 566.04 miles per hour (rounded to two decimal places)

Now, armed with the average speed, we can calculate the distance traveled in 3 hours by multiplying the average speed by the given time:

Distance traveled = Average speed × Time taken

Distance traveled = 566.04 miles per hour × 3 hours

Distance traveled ≈ 1698.12 miles (rounded to two decimal places)

Therefore, at this rate, the Boeing 747 airplane will fly approximately 1698.12 miles in 3 hours.

A transformation modifies the parent function's graph.

The graph of a parent function is changed by a transformation. Transformations come in three different flavors: translations, reflections, and dilations.

A point, line, or geometric object can be changed in four different ways that are all collectively referred to as transformations. The pre-image is the shape of the object as it was originally, and the transformed shape of the object is termed the image.

Making pictures or replicas of an object is part of transformation geometry. You are introduced to transformation geometry in grade 9 through the use of translation, reflection, dilation, and rotation.

The foundation of the problem transformation approach is the notion that, if we are unable to address the given problem directly, we will move it to a setting where we can do so. The method's fundamental component is how the problem is broken down into smaller tasks.
