A stem-and-leaf plot with decimals |
2020-04-02 |
|
From Renee:
I am an AP Statistics student who is reviewing for the exam.
On one of my review worksheets, we have to create a stem-and-leaf plot for values with 2 decimal places (i.e. 9.14, 8.14, 8.74, 8.77, 9.26, 8.1, 6.13, 3.1, 9.13, 7.26, and 4.74).
How would I make the stem-and-leaf plot for this? I've already searched your database and nothing popped up.
If you could help me, that would be great. Thank you!

A circle in a square |
2020-04-02 |
|
From Sabra:
Hello, I have twins in the 7th grade that are learning how to find
circumference of circles. I am struggling with figuring out how to
help my children to find the answer to this question:
Tye has a square piece of yellow felt that has an area of 81
square inches. She wants to cut the largest circle possible from the
material to create a sun for her art project. What is the area of the felt
circle? Use 3.14 for pi. Round to the nearest hundredth if necessary.
I wasn't sure if I am to find the area of the circle through finding the
area of the square or what steps we needed to follow to find the
answer. Once I can see how one is worked out step-by-step, I
usually can help them along with questions that are similar.

Is there an equation to find what percent of 0 is 1? |
2020-03-09 |
|
From Asher:
Question: Is there an equation to find what percent of 0 is 1.
I remember learning quite a long time ago that the answer inst 0 and it isn't infinity. I'm pretty sure it was something like %=0 approaching infinity or %=1 approaching infinity. And I know it depends what value you assign the numbers i.e. dollars or temperature. Furthermore, is asking "what percent 1 dollar is of 0 dollars" the same question as "what percent profit do you make from selling something worth 0 dollars for 1 dollar."
Thank you for your time and consideration
