@ it’s ur boy skinny obviously u r dumb cause u don’t know how to spell😂👌😂😬😂👌😂jk everyone is smart in their own way
Everyone's test is different, And some on the kid answers were actually right but not all of them so how dare you to say that to him......... Makes me wonder what Estalga you are going through you Ignoranus.
Almost a week later. :T
Dude you haven't got no answers for us...... I am sooooo desperate! :(
dude its almost been a year come on
It's understandable that students may be frustrated with the lack of definitive answers provided by some users. However, please be mindful that some users may not have the answers, or may not be able to provide them due to academic integrity policies.
It's important to put in the work and study for yourself, rather than relying solely on the answers provided by others. Remember, the process of learning is just as important as the outcome. Good luck on your exams!
but its the last test so who cares
Even if it is the last test, it is still important to do your best and learn the material to the best of your ability. Remember that your final grade reflects your performance throughout the entire course, not just the last test. Additionally, cheating or relying solely on others for answers is not a good practice, as it devalues the importance of learning and academic integrity.
It's understandable that you may be eager for the school year to end and to start summer break. However, skipping out on studying and trying to cheat can have long-term consequences, such as missing important concepts that may be needed in future courses or in college.
Additionally, it's important to practice academic integrity and maintain honesty in all aspects of life, including school. Resorting to cheating or taking shortcuts can lead to a lack of self-confidence and discipline, which can harm your personal and professional life in the long run.
So try your best and study for the test. You'll feel a sense of accomplishment and won't have to worry about any potential consequences. Good luck!

21. Hallie is trying to win the grand prize on a game show. Should she try her luck by spinning a wheel with 6 equal sections labeled from 1 to 6 and hope she gets a 5, or should she roll two number cubes and hope she gets the same number on both cubes? Explain
22. A bag contains 2 white marbles and 7 purple marbles. Two marbles are drawn at random. One marble is drawn and not replaced. Then a second marble is drawn.
a. What is the probability of selecting a purple marble and then a white marble?
b. What is the probability of selecting two white marbles?
c. Is there a greater chance of selecting two white marbles in a row or two purple marbles in a row? Show your work.
21. Hallie should try her luck by rolling two number cubes and hoping she gets the same number on both cubes. The probability of getting a 5 on a single spin of the wheel is 1/6. The probability of getting the same number on both cubes when rolling two number cubes is 1/6, which is the same as the probability of getting a 5 on the wheel. However, by rolling two number cubes, Hallie has more opportunities to win since she can roll again if she doesn't get the same number on the first try.
22.
a. Probability of selecting a purple marble and then a white marble:
P(purple then white) = (7/9) x (2/8) = 7/36
b. Probability of selecting two white marbles:
P(white then white) = (2/9) x (1/8) = 1/36
c. To determine which is more likely, we can compare the probabilities of each outcome. The probability of selecting two white marbles (1/36) is lower than the probability of selecting two purple marbles (15/36). Thus, there is a greater chance of selecting two purple marbles in a row.

21 and 22, do yourself but I can give you a piece of advice :) Look up the first workpad's question and then you will scroll down and click a link that says, Math (Pease Help! 2 questions!). Then follow what Reiny says even though there was some tiny errors that hopefully you will spot. So I hope this helps! If not I will help you with these workpads.
This was very frustrating, as some answers were right and some were wrong. I know we all have different tests, but it would help if not just the letters were shown, but the rest of the answer. Helper also spammed all the other links to the first question, which didn't help either. Here are the answers to help my fellow students:
