a spinner used for a game is divided into 4 sections yellow brown red and orange the spinner is spun 50 times and lands on brown
2 answers:
Answer: 0.76
Step-by-step explanation:
Given : Number of sections ( yellow, brown, red and orange) = 4
The spinner is spun 50 times and lands on brown 12 times, then the number of times spinner does not land on brown = 50-12=38
Then, the experimental probability that the spinner does not land on brown :_
Hence, the experimental probability that the spinner does not land on brown = 0.76

1. Take an arbitrary point that lies on the first line y=3x+10. Let x=0, then y=10 and point has coordinates (0,10).
2. Use formula to find the distance from point
to the line Ax+By+C=0.
The second line has equation y=3x-20, that is 3x-y-20=0. By the previous formula the distance from the point (0,10) to the line 3x-y-20=0 is:
.
3. Since lines y=3x+10 and y=3x-20 are parallel, then the distance between these lines are the same as the distance from an arbitrary point from the first line to the second line.
