Answer:

866/733

Step-by-step explanation:

172 divided by the total numbers

i.e 172/239+102+40+106+661+60+172+86

=172/1466

=86/733

The probability that a randomly selected person from this study tried to quit smoking  will be 0.117

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

We have been given the data in the vein diagram.

Thus, the probability that a randomly selected person from this study tried to quit smoking using a lozenge given that they also use gum will be;

Total number of person = 239+102+40+106+661+60+172+86 = 1466

Now 172 divided by the total numbers of selected person

= 172/1466

= 86/733

= 0.117

Hence, the probability that a randomly selected person from this study tried to quit smoking  will be 0.117

Answer:

The point (6,1) lies inside the circle.

Step-by-step explanation:

Equation of a Circle

A circle centered at the point (h,k) and with radius r, can be expressed with the equation:

\((x-h)^2+(y-k)^2=r^2\)

The center of the given circle is (0,0) and the radius is \(r=\sqrt{38}\), thus the equation of the circle is:

\((x-0)^2+(y-0)^2=(\sqrt{38})^2\)

Simplifying:

\(x^2+y^2=38\)

Each point (x,y) meeting the condition of the equation lies exactly on its circumference. For example, the point \((\sqrt{2},6)\) belongs to the circumference, but the origin (0,0) is inside the circle, and the point (5,5) is outside the circle.

We can tell the difference by evaluating the equation at each point. For the first point \((\sqrt{2},6)\), the equation is:

\((\sqrt{2})^2+6^2=2+36=38\)

The equation is satisfied.

For the origin (0,0):

\(0^2+0^2=0\)

For the point (5,5):

\(5^2+5^2=50\)

We can conclude that if the left side is greater than 38, the point is outside the circle, if it's less than 38, the point is inside the circle.

Let's test the point (6,1):

\(6^2+1^2=37\)

The point (6,1) lies inside the circle.

a) The set of points satisfying the equation |z| = 2 is a circle with radius 2 and center at the origin.

b) The set of points satisfying the inequality |z - 2i| < 3 is an ellipse with center at 2i and semi-major axis 3.

a) The absolute value of a complex number is its distance from the origin. So, |z| = 2 means that all points satisfying this equation are 2 units away from the origin. This forms a circle with radius 2 and center at the origin.

b) The distance between a complex number z and the number 2i is |z - 2i|. So, |z - 2i| < 3 means that all points satisfying this inequality are less than 3 units away from 2i. This forms an ellipse with center at 2i and semi-major axis 3.

A. Manager A wants the decision to be 0.4, so they would recommend a decision of 0.4 to the principal.

B. The recommendations in the Nash equilibrium would be rA = 0.4 and rB = 0.7.

(a) If Manager B always truthfully reports the state of the economy (s = 0.7), Manager A would send a recommendation that minimizes their disutility Ua. In this case, Manager A wants the decision to be 0.4, so they would recommend a decision of 0.4 to the principal.

(b) In a Nash equilibrium, both managers strategically make their recommendations based on their own utility. Manager A wants to minimize their disutility Ua, which increases as the decision deviates from 0.4. Manager B wants to minimize their disutility UB, which increases as the decision deviates from 0.7.

To find the Nash equilibrium, we need to consider the recommendations made by both managers simultaneously. Let's denote the recommendations as rA (from Manager A) and rB (from Manager B). The principal's decision, d, would be the average of the recommendations, so d = (rA + rB) / 2.

Given that both managers strategically choose their recommendations, they will aim to minimize their disutility. In this case, Manager A would recommend a decision of 0.4 (as it minimizes Ua), and Manager B would recommend a decision of 0.7 (as it minimizes UB). Therefore, the recommendations in the Nash equilibrium would be rA = 0.4 and rB = 0.7.

The correct answer is c. Inferential Statistics.

Inferential statistics is the branch of statistics that allows for drawing conclusions about a population based on the information collected from a sample. When conducting research or surveys, it is often impractical or impossible to collect data from an entire population.

Instead, a representative sample is chosen, and inferential statistics are used to make inferences or predictions about the larger population. By analyzing the characteristics and patterns observed within the sample, inferential statistics enable researchers to make generalizations or draw conclusions about the population as a whole.

This process involves applying various statistical techniques, such as hypothesis testing and confidence intervals, to estimate population parameters and assess the reliability of the conclusions. Magnitude statistics, central tendency, and effect size are important concepts in statistics, but they do not specifically address the ability to draw population-level conclusions from sample data.

Magnitude statistics focuses on the size of the effect or relationship between variables, central tendency measures summarize the central values of a dataset, and effect size quantifies the strength of an effect or relationship.

Answer:

200 x .39

Step-by-step explanation:

200 x .39= 78

Answer:

39 percent of 200 is the same as 39 per hundred of 200. We can therefore make the following equation:

39/100 = X/200

To solve the equation above for X, you first switch the sides to get the X on the left side, then you multiply each side by 200, and then finally divide the numerator by the denominator on the right side to get the answer.

39/100 = X/200

X/200 = 39/100

X*200/200 = 39*200/100

X = 7800/100

X = 78

The work above shows the long way to explain how to calculate 39 percent of 200 in order to give you a foundation and better understanding of how to calculate percentage. In the future, you could use this simplified formula:

(Y * P)/100

In our problem "What is 39 percent of 200?", Y is 200 and P is 39:

(200 * 39)/100 = 78

And once again you see that the answer is 78.

You need to deposit $13 into a account to have amount $5000 in 2 years.

Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.

The formula used to find the compound interest = \(A=P(1+\frac{r}{100})^{nt}\).

Given that, Amount =$5000, rate of interest =5.89% and time period = 2 year = 104 weeks.

Now, 5000=P(1+5.89/100)¹⁰⁴

5000=P(1+0.0589)¹⁰⁴

5000=P(1.0589)¹⁰⁴

5000=384.5P

P=5000/384.5

P=$13

Answer:

The midpoint is (4.5,-.5)

Step-by-step explanation:

The x coordinate  of the midpoint is the sum of the x coordinate divided by 2

(1+8)/2 = 9/2 = 4.5

The y coordinate  of the midpoint is the sum of the y coordinate divided by 2

(-6+5)/2 = -1/2 = -.5

The midpoint is (4.5,-.5)

Rounding to the nearest whole value, we get the estimated number of observations above 118 as 2940.

To determine the number of observations expected to be below a certain value using the 68-95-99.7 Rule, we need to find the area under the normal distribution curve up to that value.

For the first scenario:

Mean (μ) = 162

Standard deviation (σ) = 11

Value to evaluate (x) = 195

We want to find the area under the curve to the left of x = 195. This corresponds to the cumulative probability of a value being less than 195 in a normal distribution.

Using a standard normal distribution table or a calculator, we can find that the cumulative probability for x = 195 is approximately 0.961. This means that about 96.1% of the observations are expected to be below 195.

To find the number of observations, we multiply the cumulative probability by the total number of observations:

Number of observations = 0.961 * 2400 = 2306.4

Rounding to the nearest single observation, we get the estimated number of observations below 195 as 2306.

For the second scenario:

Mean (μ) = 137

Standard deviation (σ) = 19

Value to evaluate (x) = 118

We want to find the area under the curve to the right of x = 118. This corresponds to the cumulative probability of a value being greater than 118 in a normal distribution.

Using the same approach, we can find that the cumulative probability for x = 118 is approximately 0.735. This means that about 73.5% of the observations are expected to be above 118.

To find the number of observations, we multiply the cumulative probability by the total number of observations:

Number of observations = 0.735 * 4000 = 2940

Step-by-step explanation:

To find the volume of the solid generated by revolving the plane region about the line x using the shell method, we need more specific information about the given plane region and the boundaries of integration.

The shell method is a technique used to calculate volumes of solids of revolution. It involves integrating cylindrical shells along the axis of rotation. However, in order to apply the shell method, we require additional details regarding the given plane region and the boundaries of integration.

Typically, the plane region is defined by a function or an equation. For example, if the plane region is bounded by the curves y = f(x), y = g(x), and the line x = a, x = b (where f(x) > g(x) for all x in the interval [a,b]), we can proceed with the shell method.

To calculate the volume using the shell method, we integrate the circumference of each cylindrical shell multiplied by its height. The differential height is given by Δh = f(x) - g(x), and the differential circumference is 2πx.

The integral expression for calculating the volume using the shell method is:

V = ∫[a,b] 2πx * (f(x) - g(x)) dx

By evaluating this integral over the appropriate interval [a,b], we obtain the volume of the solid generated by revolving the given plane region about the line x.

However, without specific information about the plane region, the equations or functions defining it, and the boundaries of integration, it is not possible to provide a numerical value for the volume. If you can provide more details or specify the plane region, I would be happy to assist you further in using the shell method to determine the volume.

It is recommended that you have a surface interval of at least one hour when making repetitive dives with enriched air.

The surface interval refers to the time spent on the surface between two consecutive dives. It is an essential aspect of dive planning, especially when using enriched air or nitrox, which contains higher levels of oxygen than regular air. Enriched air diving allows for extended bottom times due to reduced nitrogen absorption, but it also brings additional considerations for safety.

During a dive, nitrogen accumulates in the body tissues. If a diver ascends to the surface and immediately begins another dive without a sufficient surface interval, there is a risk of developing decompression sickness (DCS) or the bends. DCS occurs when dissolved nitrogen forms bubbles in the tissues due to a rapid decrease in pressure. These bubbles can cause various symptoms, ranging from mild joint pain to more severe neurological complications.

To minimize the risk of DCS and allow for the elimination of excess nitrogen, it is recommended to have a surface interval between dives. The standard guideline is to wait for at least one hour on the surface. This interval allows the body to off-gas nitrogen, reducing the likelihood of bubble formation during subsequent dives.

However, it's important to note that the surface interval may vary depending on factors such as the depth and duration of the previous dive, the diver's age and physical condition, and the specific gas mixture used. In some cases, divers may opt for longer surface intervals to ensure a more conservative approach to decompression.

In conclusion, when making repetitive dives with enriched air, it is crucial to adhere to the recommended surface interval of at least one hour. This interval allows the body to off-gas excess nitrogen and reduces the risk of decompression sickness. However, it is always important to consider individual factors and consult diving tables, dive computers, or a qualified dive professional to determine the appropriate surface interval for safe and enjoyable diving experiences.

To find a₂ and a₃ in a geometric sequence, we need to determine the common ratio (r) first.

In a geometric sequence, each term is obtained by multiplying the previous term by a constant ratio, denoted as "r." Given that a₁ = 3 and a₅ = 768, we can use these values to find the common ratio.

We can use the formula for the nth term of a geometric sequence: aₙ = a₁ * r^(n-1).

Substituting a₁ = 3 and a₅ = 768, we have:

a₅ = a₁ * r^(5-1)

768 = 3 * r^4

Now, we can solve for the common ratio, r, by dividing both sides of the equation by 3 and taking the fourth root:

r^4 = 768/3

r^4 = 256

r = ∛(256)

r = 4

Now that we have the common ratio, we can use it to find a₂ and a₃.

To find a₂, we use the formula a₂ = a₁ * r^(2-1):

a₂ = 3 * 4^(2-1)

a₂ = 3 * 4

a₂ = 12

To find a₃, we use the formula a₃ = a₁ * r^(3-1):

a₃ = 3 * 4^(3-1)

a₃ = 3 * 16

a₃ = 48

Therefore, a₂ = 12 and a₃ = 48 are the values for the second and third terms in the geometric sequence, respectively.

Step-by-step explanation:

Let x be the parts of 25% dextrose and

y be the parts of 10% dextrose are mixed so that

20% dextrose mixture is obtained.

amount of dextrose in the mixture will be 20% of (x+y).

We have to find the value of \(\frac{x}y \ OR\ x:y\)

Now, we can apply the concept that sum of amount of dextrose in the two liquids will be equal to the amount of dextrose in the mixture.

\(\Rightarrow x \times 25\% + y \times 10\%=(x+y)\times 20\%\\\Rightarrow x \times\dfrac{25}{100} + y \times \dfrac{10}{100}=(x+y)\times \dfrac{20}{100}\\\Rightarrow x \times25 + y \times 10=(x+y)\times 20\\\Rightarrow 25x + 10y=20x+20y\\\Rightarrow 25x -20x =20y-10y\\\Rightarrow 5x=10y\\\Rightarrow \dfrac{x}{y} = \dfrac{10}{5}\\\Rightarrow \bold{x:y=10:5\ OR\ 2:1}\)
