UpStudy has been a total lifesaver for me this semester. I was pretty nervous about Calculus I since math wasn't my strongest subject in high school, but UpStudy has basically become my go-to study buddy.
Jason, College, United States
Math is my biggest weakness. The signs and the numbers are just too confusing for me, especially when there's a four-digit number or more. And I also have anxiety when I raise my hand, and I am afraid that if I say a solution that might be wrong, I'll be humiliated in front of the whole class. That's so embarrassing.

Like that time when I was already 2 hours doing my homework and nothing was working for me to understand what was going on.
Sarah, High School, Brazil
Like last week, I was completely lost on implicit differentiation during class, but I went back to my dorm and used UpStudy, scanned my problems, did their practice problems, and it finally clicked. The best part is I can get the most detailed explanation and guidance!!
Jason, College, United States
My "aha!" Clicked in when UpStudy helped me with my Physics Homework even though I'm in newbie and I just got UpStudy I still think that I will use it or at least the next 20 years 🫣😂📚
Abigael, High School, Switzerland
When I was so lost in my math homework, I was trying already 2 hours to be focused but I wasn't getting it at all! And so I tried the app, I wasn't expecting to understand everything at once, but with the AI tutor's help I did it!!
Sarah, High School, Brazil
I'm pretty sure there are a bunch of other freshmen in my class using UpStudy too. It's honestly kind of amazing that such a helpful app. Makes me feel a lot more confident about taking Calc II next semester.
Jason, College, United States
UpStudy is a great app to help you with your studies, especially if you're struggling. I used to practice hours and hours, and I still got a bad grade. But ever since I got UpStudy, I only have to learn 1 hour a day for any test or pop quizzes, and boom! I score well on every test! You should definitely try it out!
Abigael, High School, Switzerland
UpStudy is such a great app, especially If you are a self-taught person the AI tutor can do so much for you and your apprenticeship.

(c) Suppose three different individuals conduct the same statistical study, such as estimating the average commute time of students at a college. It is possible that all itree studies end up with different results. Choose the correct answer below.
A. False. Statistics is a form of mathematics, which means that as long as correct procedures are used, all studies should obtain the same results, even if different studies used different procedures.
B. True. If at least two of the individuals made different errors in their studies, then it is possible that all three studies end up with different results. This is the only way for all three studies to end up with different results.
C. False. Only two results are possible for any statistical study. Therefore, if all three individuals conduct the same statistical study, at least two of the three individuals must obtain matching results.

00. A cook at a restaurant is calculating the amounts of ingredients needed to make
soup for the next 5 days. For each of these days, she will use \( 2 \frac{1}{8} \) pounds of
carrots and \( y \) pounds of celery. She will use a total of \( 19 \frac{3}{8} \) pounds of carrots and
celery to make all the soup.
Which equation shows how to find the number of pounds of celery, \( y \), she will use
to make soup each day?
A. \( y=19 \frac{3}{8}-2 \frac{1}{8} \)
B. \( y=19 \frac{3}{8} \div 5 \)
C. \( y=\left(19 \frac{3}{8}-2 \frac{1}{8}\right) \div 5 \)
D. \( y=\left(19 \frac{3}{8} \div 5\right)-2 \frac{1}{8} \)
