There are 24 students in the class.
3/4 = 0.75
18/3 = 6
18+6 = 24
5 out of 13 is roughly 1/7 but the chance of it being defective or not you have 5/13 of a chance of being defective or not
Answer: 3/4
Step-by-step explanation: Doing order of operations we first do 7x1=7, then 7-4=3, then finally do 4x1/4=3/4.
Hope this helps! :)
X+1 / x-1 = 14/20
20(x + 1) = 14(x - 1)
20x + 20 = 14x - 14
20x - 14x = -14 - 20
6x = -34
x = -34/6
x = -17/3
In short,Your Answer would be Option D
Hope this helps!
