Vertical line is a way to determine whether a functin is a function or not.
Answer: 4%
Step-by-step explanation: 50 x 2 = 100
2x2=4 4/100 or 4%
Theoretical probablity=desiredoutcomes/totalpossibleoutcomes
desired=number of white marbles=20
total possible=red+blue+white=30+50+20=100
so theoretical probablity=20/100=2/10=0.2=20%
Answer: D
Step-by-step explanation:
The perimeter is all the sides added up
2.5x + 2.5x + 10 + 2 + 10 =>
5x + 22
It is also given that the perimeter is 10.5x
meaning that both these values are equal
5x + 22 = 10.5x
