Answer:
c = 3√5 ≈ 6.708
Step-by-step explanation:
Use the Pythagorean Theorem because this is a right triangle.
a^2 + b^2 = c^2
3^2 + 6^2 = c^2
9 + 36 = c^2
45 = c^2
√45 = c
<u>c = 3√5 ≈ 6.708</u>

There are 10+14+6=30 total coins in the bag including 10 pennies,14 buckles and 6 dimes
Then,
P(removing a penny after first pick):
10/30 or 1/3
Now, there are only 9 pennies, and total amount of coins decrease by one count which is 29
P(remove a nickel after second pick):
14/29
Now, there are only 28 coins in total left in the box, so
P(removing a dime):
6/28 or 3/14
Lastly, to find the probability or compound event, take:
1/3×14/29×3/14=42/1638
Simplify 42/1638
21/819. As a result, the probability you remove a penny and nickel and a dime in that order is 21/819. Hope it help!
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.
