Answer:
Step-by-step explanation:
Let's solve the inequality step-by-step:
Step 1. Add 12 to both sides of the inequality
Step 2. Multiply both sides by -4 and reverse the inequality (since you are multiplying by a negative quantity)
We can conclude that the correct answer is the third option.
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
Answer:
Step-by-step explanation:
5 < √x < 6
25 < x < 36
Alan = 30m² olan karenin kenar uzunlukları 5m ile 6m arasındadır.
1. 20x + 5x = 75
25x = 75
To find the answer, divide 75 by 25. The answer is 3.
2. 10x - 4x = 28
6x = 28
That's actually 4.6 repeating. Is that the problem we were supposed to do, or did you make a mistake? In any case, do tell me in the comments whether it was correct, or whether that is indeed the problem for #2.
