A survey was conducted of students at a highschool and at a college to determine students favorite subjects. The results are shown in the table. What percentage of the students are college students that prefer history? Highschool-
history(80)
math (50)
science (70)
total(200)

College-
history (70)
math(60)
science (70)
total (200)

History total (150)
Math total (110)
science total (140)

35%

Step-by-step explanation:

So I’m not sure this is high school math because i’m still in grade school but...

So what you have to do is make a ratio

so if 70 students out of 200 in college prefer history the ratio should be 70 to 200 or 70:200

Then you want to do 70 * 200 which then you get a answer of .35

then to make .35 into a percent you move the decimal two spaces to the left for a answer of 35%

Hope this helps!

no i do not : ( what is it?

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
