Determine the additional number of students needed for the teacher not to cancel the class
First, we need to calculate the number of students for the teacher to cancel the class.
Represent this with x.
So, we have:
Make x the subject
Substitute values for Total and S1
This means that if less than 7 additional students come to the class, the teacher will cancel the class.
So, for the teacher not to cancel the class, the students must be 7 or greater (i.e. 7, 8, 9, 10....)
Add total rolls:
The number of rolls is the height of each bar:
14 + 12 + 16 + 15 + 13 = 70
70 total rolls
The numbers greater than 3 are 4 and 5
4 was rolled 15 times and 5 was rolled 13 times
15 + 14 =28 Total times
The prInability of that happening would be 28/70 which reduces to 2/5
The answer as a fraction is 2/5 which is 40% as a percentage.
Answer: X=31
Step-by-step explanation:
The angles are supplementary because they add up to 180 degrees. Therefore, we will make the angles equal 180 degrees using
3x+25+2x = 180
combine like terms
5x+25=180
subtract the 25 from both sides
5x=155
divide each side by 5
answer x=31
3/5 = ?/300
We multiply 5 by 60 to get 300
So you do the same to 3
3x60= 180
180
It’s a strong relationship. I had statistics last year. The closer it is to 1, the stronger the relationship is, the closer to zero it is, the weaker the relationship is.
