Assuming number cube has 6 sides
probablity is (desiredoutcomes)/(total possible ouctomes)
since it is 450 times
total possible outcomes=450
experimiental probablity is the one actaully obtained by doing it
theoretical is the predicted amount
so theoretical probablity of rolling a 3 is 1 number out of 6 or 1/6 or 75 times out o 450 times
experimiental is the actaull one so67 out of 450 or 67/450
theoretical is 1/6 or 75/450
experimental is 67/450
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
Hello there, and thank you for posting your question here on brainly.
Since we know what both of the exponents are, we can rewrite the equation for it.
3 * 2 - (-4)
We can evaluate from here.
I can see we have a positive number subtracting a negative number.
Use the rule where x - (-y) = x + y
2 * 3 + 4
Now we can get solving.
2 * 3 ==> 6
6 + 4 ==> 10
10 is the final answer.
Hope this helps! ☺♥
Answer:
The answer is 4
Step-by-step explanation:
