Step-by-step explanation:
-8 - -4= -8+4=-4
16- -4=20
8- -4=12
-9--4=-5
Part a)
Identify the variable and categoriesBy reading the above statement, we can find that there are two variables and each variable has 2 categories. The variables and their categories are:
1) Class Number
This variable is further divided into 2 categories i.e. Class 9th and Class 10th.
2) Participation in Extracurricular activities
This variable is further divided into 2 categories based on if students participated or not.
Part b)Set up and fill 2 way table.Since, we have 2 variables and each variable has 2 categories the number of data cells will be 2 x 2 = 4 cells
There are total 100 students. 40 students are in class 10th. This means 60 students are in class 9th.Out of 40 students in class 10th, 18 students participate in at least one extracurricular activity. So remaining 22 students do not participate. 32 students from class 9th participate in extracurricular activities, this means the remaining 28 students do not participate. Based on this data, we can fill up the table as shown below
The greatest common factor of this can be solved by looking at the individual parts and splitting it up.
First, we have 28 and 7. Well, thats an easy one. 7 goes into 28 4 times so we are now left with 4 and 1.
We can also write the rest of this like this 4(x*x*y) - 1(x*y*y*y*y*y)
Now, what values are in both equations. We have one x and one y that can be taken out of both.
We end up with 7xy(4x-7y^4)
