Answer:
394/679
Step-by-step explanation:
Probability is the measure of likelihood or chance that an event will occur.
Probability = Possible outcome of event/Total outcome
Total number of people asked if they had run a red light = number of people that responded 'yes' + number of people that responded 'no'
Total outcome = 394+285
Total outcome = 679
Possible outcome = number of people that responded yes = 394
Probability that if a person is chosen at chosen at random, they have run a red light in the last year will be 394/679
Step-by-step explanation:
For the point (5,8) to be a solution to the equations, when you insert x=5 and y=8 , they have to equal to the given values
substituting (5,8) into 4x+y
4(5)+8
=20+8
=28
substituting(5,8) into x-y=3
5-8
= -3
This is a convenience sample, since they are interviewing people that are already out in the park.
Answer:
31.4
Step-by-step explanation:
first you take your radius of 5 and times it by 2.
