Step-by-step explanation:

The expected utility of Marlee with the ticket from Fony is 28.

The utility function of Marlee is given by u(x) = x+k. Here, k equals 100 if Marlee gets to go to the concert and equals 0 otherwise.

Marlee has $100 to buy tickets to the Fleet Foxes concert in Atlanta. She found two different websites selling tickets, Fony Front Seats and Best Tickets. If she buys a $20 ticket from Fony, there is a 60% chance that the ticket is fake, but she won't know until she gets to the concert.

If she buys a $60 ticket from Best Tickets, the ticket is certainly real. The seat placements for both tickets are identical and it costs $10 in gas to get to the concert.

Marlee's utility function is given as u(x) = x+k, where k equals 100 if Marlee gets to go to the concert and equals 0 otherwise. Her goal is to maximize her utility function.

Marlee is facing a trade-off between the cost of the ticket and the probability of getting a real ticket.

If she buys a $20 ticket from Fony, there is a 60% chance that the ticket is fake, but she won't know until she gets to the concert. Thus, there is a 40% chance that the ticket is real.

So, the expected utility of Marlee with the ticket from Fony is given by,

0.6u(0)+0.4u(100-20-10)=0.6(0)+(0.4)(70)=28

Therefore, the expected utility of Marlee with the ticket from Fony is 28. This indicates that Marlee will not be able to go to the concert if she buys the ticket from Fony Front Seats.

If she buys a $60 ticket from Best Tickets, the ticket is certainly real. Therefore, the expected utility of Marlee with the ticket from Best Tickets is,

u(100-60-10)=u(30)=30+100=130

Therefore, the expected utility of Marlee with the ticket from Best Tickets is 130.

This indicates that Marlee should buy the ticket from Best Tickets to get the maximum utility.

Therefore, Marlee should buy her ticket from Best Tickets because she will receive the maximum utility if she buys the ticket from Best Tickets.

About 11.90% of students scored 59.99 or lower on the exam and failed the course (since this is a proportion, we can multiply it by 100 to get the percentage).

To determine the percentage of students who failed the course, we need to find the proportion of students who scored 59.99 or lower on the exam, and then convert this proportion to a percentage.
First, we need to standardize the cutoff score of 59.99 using the formula:
z = (x - μ) / σ
where x is the cutoff score, μ is the mean, and σ is the standard deviation.
Plugging in the values given in the question, we get:
z = (59.99 - 73) / 11 = -1.18
Next, we look up the proportion of scores below a z-score of -1.18 in a standard normal distribution table (or use a calculator or software). This proportion is approximately 0.1190.
Therefore, about 11.90% of students scored 59.99 or lower on the exam and failed the course (since this is a proportion, we can multiply it by 100 to get the percentage).
In other words, roughly 12% of the students failed the course based on the given criteria.

This assessment focuses on using a line plot to represent a data set related to snowfall amounts. It requires determining the largest and smallest amounts of snow, counting occurrences of a specific value.

The new values of the data can vary depending on the original data set and the desired difference between the largest and smallest amounts of snow. Let's consider an example: If the original largest amount of snow was 10 inches and the smallest amount was 5 inches, and the new difference should be 3 inches, one possible combination could be increasing the largest amount to 12 inches and decreasing the smallest amount to 9 inches.

Alternatively, the largest amount could be decreased to 7 inches, while the smallest amount is decreased to 4 inches. These are just two examples, but there can be multiple valid combinations of new values that satisfy the given conditions. #

The function is 130/2.

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input. A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X.

According to question,

\(\int\limits^9_0 {f(x)} \, dx \\ \int\limits^7_0 {f(x)} \, dx+\int\limits^9_7 {f(x)} \, dx\\ \int\limits^7_0 {7} \, dx + \int\limits^9_7 {x} \, dx\\ (7x)^{7} _{0} + (\frac{x^{2} }{2})^{9} _{7}\)

The question is not properly structured. Here is the complete question.

For cones with radius 6 units, the equation V=12\pi h relates the height h of the cone, in units, and the volume V of the cone, in cubic units. Sketch a graph of this equation on the axes.

The formula for calculating the volume of a cone is expressed as shown;

\(V = \frac{1}{3} \pi r^{2} h\) where r is the radius and h is the height.

Given radius r = 6units, on substituting;

\(V = \frac{1}{3}*\pi *6^{2}*h\\ V = \frac{36\pi h}{3}\\V = 12\pi h... (1)\)

It can be seen from the derived volume of the cone that it is linear in nature. The volume of the cone has a linear relationship with its height. As the volume increases, the height also increases and vice versa.

Generally for a direct variation

Many researchers do not explicitly refer to significance levels. Instead, they simply obtain the P value and use it (or let the reader use it) to assess the strength of the evidence against the null hypothesis.

In statistical hypothesis testing, the null hypothesis is the default or initial assumption that there is no relationship or difference between two or more groups being compared.

The goal of hypothesis testing is to determine whether the evidence in the sample provides enough evidence to reject the null hypothesis and support the alternative hypothesis.

This decision is made based on the significance level, which is the probability of rejecting the null hypothesis when it is actually true.

The significance level is typically set at 0.05 (or 5%), which means that there is a 5% chance of rejecting the null hypothesis even if it is true.

Instead of reporting a significance level, some researchers report the P value, which is the probability of obtaining a test statistic as extreme or more extreme than the one observed, assuming that the null hypothesis is true.

If the P value is less than the significance level, then the null hypothesis is rejected, and the results are considered statistically significant. If the P value is greater than the significance level, then the null hypothesis is not rejected, and the results are considered not statistically significant.

Therefore, the P value can be used to assess the strength of the evidence against the null hypothesis, without explicitly referring to a significance level.

The smaller the P value, the stronger the evidence against the null hypothesis, and the more likely it is that the alternative hypothesis is true.

The larger the P value, the weaker the evidence against the null hypothesis, and the less likely it is that the alternative hypothesis is true.

Many researchers do no longer explicitly refer to importance levels. Instead, they virtually achieve the P fee and use it (or let the reader use it) to determine the power of the proof in opposition to the null hypothesis.

In statistical speculation testing, the null speculation is the default or preliminary assumption that there is no relationship or distinction between two or extra businesses being compared.

The purpose of speculation checking out is to decide whether or not the proof in the pattern gives ample proof to reject the null hypothesis and help the choice hypothesis.

This choice is made primarily based on the magnitude level, which is the chance of rejecting the null speculation when it is in reality true.

The importance degree is normally set at 0.05 (or 5%), which capability that there is a 5% risk of rejecting the null speculation even if it is true.

Instead of reporting a magnitude level, some researchers file the P value, which is the chance of acquiring a check statistic as severe or greater severe than the one observed, assuming that the null speculation is true.

If the P fee is much less than the magnitude level, then the null speculation is rejected, and the consequences are viewed statistically significant.

If the P cost is larger than the importance level, then the null speculation is now not rejected, and the consequences are regarded no longer statistically significant.

Therefore, the P price can be used to verify the electricity of the proof towards the null hypothesis, besides explicitly referring to a magnitude level.

The smaller the P value, the better the proof towards the null hypothesis, and the extra possibly it is that the choice speculation is true.

The large the P value, the weaker the proof in opposition to the null hypothesis, and the much less in all likelihood it is that the choice speculation is true.

The center of the ellipse is the midpoint between the two foci, which is ((7+1)/2, -1) = (4,-1). The distance from the center to each focus is 3, which is half the length of the major axis.

Therefore, the distance from the center to each vertex is sqrt(5), and the length of the minor axis is 2sqrt(5). Using the standard form of the equation of an ellipse with center at (h,k), major axis of length 2a, and minor axis of length 2b, we have:

(x - h)^2 / a^2 + (y - k)^2 / b^2 = 1

Plugging in the given information, we get:

(x - 4)^2 / 3^2 + (y + 1)^2 / (sqrt(5))^2 = 1

Simplifying, we get:

(x - 4)^2 / 9 + (y + 1)^2 / 5 = 1

Therefore, the equation of the ellipse is (x - 4)^2 / 9 + (y + 1)^2 / 5 = 1.

Answer:

d = 1 + 3p  

Step-by-step explanation:

Leon already ran 1 miles on his own and he is expected to cover a distance d of 3 miles during each practice. The number of practices is expressed as p and the distance covered is expressed as d.

For every track practice he is expected to cover a distance of 3 miles. Recall he has already cover 1 mile on his own.

Therefore, the relationship between the practices p and the distance d can be expressed as follows.

number of track practice = p

distance covered = d

The distance covered  d in miles is 1 miles plus the number of track practice p multiply by 3

d = 1 + 3p

It is true, as The term "ecological correlation" refers to correlations based on rates or averages that frequently appear in political science or sociology and tend to exaggerate the significance of a link.

Correlations describe the connections between different variables. Strong, weak, positive, or negative expressions are all possible. 1 = Causation need not always follow from correlation. A statistical measure of the linear relationship between two variables is called correlation (that is, do they change at a constant rate). Without defining cause and effect, this is a common method for illustrating straightforward connections. To illustrate the connection between two quantitative variables, statistical language employs correlation. Additionally, we consider that this connection is linear. In other words, when one variable changes by a given amount, the other variable also changes by a fixed amount, but only by one unit.

The paper airplane will not hit the ground within the given time frame.

To find the equation for h( t), we need to find the rate of change or the  pitch of the function. We can do this by chancing  the difference in height and time for any two points on the line. Let's choose the first two points,( 0,200) and( 1,208).  

pitch = ( change in height)/( change in time)  

pitch = ( 208- 200)/( 1- 0) =  8  

So, the equation for h( t) can be written in  pitch- intercept form as   h( t) =  8t b  

To find the value of b, we can use any of the given points.

Let's use( 0,200)   200 =  8( 0) b  b =  200  

So, the equation for h( t) is   h( t) =  8t 200  

To find how long it'll take the aeroplane to hit the ground, we need to find when h( t) =  0,

since that would mean the height is 0  bases or the ground  position.   0 =  8t 200   working for t,

we get   t = -25

Since time cannot be negative the paper airplane will not hit the ground within the given time frame.

The difference between groups and the sample size makes the results of a study statistically significant.

Statistical significance is a measure of the likelihood that the results of a study are not due to chance. In order for a result to be statistically significant, it must meet two criteria:

The difference between groups must be large enough to be unlikely to occur by chance. This is typically assessed using a statistical test such as a t-test or an ANOVA.

The result of the test is expressed as a p-value, which represents the probability of obtaining the observed results if there were no true difference between groups. A p-value of less than 0.05 (or 5%) is generally considered to be statistically significant.

The sample size must be large enough to reduce the possibility of sampling error. A larger sample size generally increases the power of a study, making it more likely to detect a true effect.
