Davis pose la question :
i don't know how to answer this question. please help!
a survey about student government shows the following results
110 like the program
120 think the program is unnecessary
210 plan on running for student government next year
if this information is put in a circle graph,what is the central angle for the students who like the program?

A parent pose la question :
Refer to the graph given below and identify the graph that represents the corresponding function. Justify your answer.
y = 2x
y = log2x
I can figure out what line on the graph is which equation but unsure what is meant by justify your answer.

George pose la question :
1. What is the main difference between a broken-line graph and a histogram? Both represent continuous variables.
2. What is the correct way to read a multiplication array: x-axis first and then y-axis, other way around or it doesn't matter?

JJ pose la question :
Is there a way to find the intersections of these graphs algebraically?
x^2 + y = 4 & 2x - y = 1
I got (1.45, 1.9) and (-3.45, -7.9) with a graphing calculator.
AND THESE...
y = 3.29x & y = 5.5(x^0.5)+ 10000
I got x at 3133 with a graphing calculator.

Benjanim pose la question :
How do I find the points of intersection of the two functions:
1) y = 2 - (e^-x)
2) y = 1 + (x^2)
I know that I have to set them equal to each other, but I can't solve for x. Please help :-)

Double bar graphs |
2001-09-09 |
|
Leslie pose la question :
My daughter has a homework problem in which she is graphing data from two frequency tables onto a double bar graph. The graph shows how many students worked in a program in two different years, grouped by age. In the first age group, one of the years has no students working, while there were students in that age group in the other year.

A student pose la question :
If, for example, 4x2-12x+9=0 and -4x2+12x-9=0, which I'm assuming it does since you can derive that equation from the first, why do those two equations have different graphs?

Broken line graphs |
1999-10-19 |
|
Lori Samara, Kristi Cameron and the 4th grade students pose la question :
Students in Ms. Cameron's grade 4 class were wondering if a broken line can be used anywhere in the range on the y - axis when creating a broken line graph? They understand that the broken line can be used at the 0 on the broken line but what if there is a large gap in the data from 100 - 200? What do we do? The text book and mathematics dictionary do not answer these questions.
