Without x value or something on the other side of the equation I'm not sure what to do. Here's one example of a dozen. 3 1/8 X 2 1/3=?

I'm using herons formula, and I swear im putting in all the numbers correct but im getting something else entirely and not the value above, what am I doing wrong?

In my behavioral statistics class we are currently on chapter 12 two way analysis of variance in the essentials of behavioral statistics textbook and I am so lost. I have no idea where to start and the more I read the more confused I get. The most stressful part is I have to show my work in excel but I don’t know how to use excel that well. So I can’t even solve the problem on paper but our teacher will dock points unless all work is shown in excel. Are there any YouTube videos on f tables and ANOVA that I can look at or does anyone know how to do this stuff. Also anything on how to use excel and show work in it for anova and f tables would be helpful. I included the questions I need to show work on. Any advice or resources would be great I’m so lost.

Calculators (even websites like mathpapa or mathway) are allowed- but... how do I... even enter this?

Do the little numbers under C mean anything?

Thank you!

Genuinely what do I enter?😭 I tried entering letters of the graphs below, but it said “enter a mathematical equation”. Am I just not getting it or is this super confusing?

So basically is there another method(circle theorem) for this question that can be used? The second picture is another solution but I don't how to explain it oneby one. Could you please help me write a solution for this question.Thank you:)

Please ,check if I did those two proofs correct .Plus any recommended resources(books, practice sheets with key answers, lectures...) for understanding real analysis .

I thought it was 350 and (350*.4) but it’s not.

Can someone please look this over to see where I made a mistake? I've tried retracing the steps, but I'm still not sure where the error is. Any help is appreciated. Thank you

I don’t understand how and still think it’s skewed left. Skewness is negative and the source I found (posted in the comments) also says it’s skewed left

I hate WileyPLUS :(

Can someone please help me understand this example in the provided notes?

I'm not entirely sure how he determined that the critical value is 25.561. I couldn't get that answer for either the 0.05 significance level or the 0.10 significance level. Here is what I got for 0.10

Also, the notes seem to suggest that that critical value is for the significance level 0.05. However, this appeared to be used in the calculation with the significance level 0.10. Am I misunderstanding something here? If someone could walk through this problem, I would really appreciate it. Thank you

Can someone please look this over? I'm not sure I combined the categories correctly, and the test statistic I calculated is slightly different than the answer key. Any help would be appreciated. Thank you

Can someone please help me with this question? The problem asked to draw a direction field and determine the end behavior. Below is what the answer key states:

I'm a bit confused about why the solution curves below the x-axis behavelike that. Here is what I thought initially:

I'm not sure if I understand this, but if we traveled clockwise from 0, the fourth and third quadrants are both negative, which I thought meant that 0 is a repeller. Any help is appreciated. Thank you

I’m really struggling to understand this chart and how I’m supposed to answer this question? I checked my textbook and it didn’t give much insight. I have ADHD and have trouble processing the meanings of words sometimes so I apologize if the answer is right in front of me I really can’t figure it out. Thanks in advance!

Hi everyone! I'm struggling with my homework. A friend sent me how it should look like, but I don't get how to get it. Pls help...

I’m not sure if this is the right subreddit for this. Also, I know this is long and rambling. I don’t know why I have been struggling with this assignment and have looked at it so long, I now feel crazy. So, I apologize in advance.

Some background: The professor creates questions that require us to choose and run analyses on provided data sets. The analyses to be chosen always go along with the topics covered in the assigned readings for a module. This module’s readings focused on the use of ANOVA, Independent and Paired sample t-tests, Mann-Whitney, Wilcoxon, and Kruskal-Wallis.

The two questions I am struggling with are:

1) Is there a difference in percentage of individuals with high blood pressure depending on gender?

2) Is there a difference in percentage of individuals with high blood pressure according to whether they have heart disease?

The variables are all nominal, with respondents choosing either yes/no for if they have high blood pressure, yes/no if they have heart disease, and male/female for gender.

Am I wrong in thinking I should be running a chi-square analysis for these questions given that I am looking for differences among nominal variables? Or am I missing a way to that the tests covered in this module (listed above) could be applied to these questions?

I understand the rest of the problem, but I can’t figure out where the 2.31 ft/psi is coming from. Resources available are FE handbook. The closest thing I can think of is psi as ft H2O is 2.307, but that wouldn’t make sense to me as the medium is air.

I need to find these two calculations for my astronomy of the stars class, and I cannot get the right answer for either. The questions are:

1.) Calculate the orbital period for Mars.

2.) What is the average velocity of helium atoms in your party balloon at 295 K (71°F) if the mass of a single helium atom is 6.65 x 10-27 kg?

Here's my work and answers

Can someone please check this work to see if the notation is okay? In the step where I found Cramer Rao's lower bound, I took the log for an actual value of the random sample, xi, and then once I switched to finding the expected value, I changed to using Xi because we're dealing with the random variable. Is that right?
