Answer: x = 25
Step-by-step explanation: im pretty sure you would square 5 and get 25 then 15 and get 225, then you would divide those two numbers 225 and 25 and get 25
Answer:
(x - y)(j - s).
Step-by-step explanation:
jx + sy - sx - jy
= jx - sx + sy - jy
= x(j - s) - y(j - s)
= (x - y)(j - s).
Answer:
The answer is b because if you move it to the right you don't go to the other side
Answer:
The probability is 52/83
Step-by-step explanation:
In this question, we are tasked with calculating the probability of having a student who is a sophomore or a student that wears glasses.
To do this, what we do is to first calculate the probability of having a student that is a sophomore, then calculate the probability of having a student wearing glasses. Now, considering the linking word or between the two cases, wherever we have or in probability, we are to add.
Firstly , let’s calculate the number of students we have = 6 + 13 + 5 + 27 + 9 + 23 = 83 students
The total number of sophomores we have is 5 + 27 = 32
Thus, the probability of having a sophomore is 32/83
The second case is that if a student that wears glasses. The total number of student wearing glasses is 6 + 5 + 9 = 20 students
The probability of finding a student wearing glasses is thus 20/83
Now, the probability of finding a student who wears glass or is a sophomore is 20/83 + 32/83 = 52/83
2190/8760 simplifies to 1/4, or 25/100. This is 25 percent.
