When two linear equations have only one solution the two lines on a graph would intersect each other ( they would only touch in one spot).
Getting two heads in a row does not change the probability of getting a tail. There is a 50/50 chance for both heads and tails each time you flip a coin, because there are two possibilities each equally possible. The 50% probability of getting a tails is not a guarantee. It's possible to get more heads than tails, or vice versa. What the probability means is that on average the results are about equal, and you have an equal likelihood of getting either result.
Mythbusters has an episode on this, actually. They explain it really well. I recommend you watch it.
Answer:
Her heart beats 75 times per minute.
Step-by-step explanation:
Okay, for this one, I recommend setting up a proportion table. First you will figure out that her heart beats 225 times approximately in 3 minutes (no duh), and literally all you have to do is divide 225 by 3. That's all! Then you'll get 75! I hope this helped you!
Answer:
1: proportional
2: non-proportional
3: non-proportional
4: non-proportional
5: proportional
6: proportional
7: non-proportional
8: proportional
9. proportional.
10. proportional.
11. non-proportional.
12. proportional.
Step-by-step explanation:
I'm unsure how the proportional ones are actually calculated depending if it requires a dot on the exact origin, but depending on what I can graphically view and assume; every graph with the line running through the origin is proportional and every graph where the line does not run through the origin is non-proportional.
513 flowers because if you divided 2,050 by 4 you get 512.5, but if you round you get 513
