Okay so the answer would be D
I don't know if you know any of this but I'm gonna do my best to explain it to you
So when you have coordinates, lets say ( 3,2) Your three is going to be on your x- axis and the 2 on the y-axis. (the x goes straight across, the y is up and down) When graphing you would count over right 3 on the x and the once you hit that you would go up 2, that is where your point goes. Same with negative if you had (-3,2) you would go left ( since it is negative) 3 and up 2. The way I figured your question out was I just put in all the coordinates and if one of them wasn't on the line, it isn't it. D has all its coordinates on the line. It takes a little to understand where the negatives and positives are on the graph and which way to go but just practice, it becomes fun after a while
I'm sorry if that didn't make much sense, if you were right here i could show you easier but I hope it helps somehow :)
Answer:
Well it depends on many things, How high u toss the coin, what angle u catch it at, the many times that it spun while it was in the air, and if she decides the timing, as in if she's going to catch the coin, or let it fall in her hand. I'd say the coin will land on heads, thing is I kinda can't explain it without it sounding like a crazy or dumb explanation lol. if u want me to explain it with my theory, let me know
Solution: We are given that the grade point average of undergraduate students at one university have a normal distribution, with mean, standard deviation,
We have to find the percentage of the students whose grade point averages are no more than 3.36, i.e., P(x<3.36).
We need to first find the z-score.
Now we have to find . Using the empirical rule, we know that 97.5% data lies below 2 standard deviations above mean.
Therefore, using the empirical rule, 97.5% of the students have grade point averages that are no more than 3.36.
