Answer:
independent, 1/4
Step-by-step explanation:
The events are independent because what occurs on the first flip does not affect the second flip
P(heads) = 1/2
P(heads, heads) = 1/2*1/2 = 1/4
There are as many fractions equal to 4/5 as there are numbers, but here are a couple that fit:
20/25
8/10
12/15
<span>100/125
...etc. Hope that answered your question :)

The formula for arc length which is measured in units not degrees is
, where 2 pi r is the circumference. We were given the circumference as 12 pi, so we can fill in the rest of the formula and the find the length of the arc that is intercepted by that 330° angle.
gives us, after multiplying in the pi, an arc length of 34.56 units.

<h2>Solving the Question</h2>
In this case, we're given the following information:
- Mother = $9
- Grandmother = $1 per mile
- Isabelle walks <em>x</em> miles, mother pledge = grandmother pledge
The mother's donation of $9 will not change <em>no matter how many miles Isabelle has walked</em>, so if both the mother's and grandmother's donations are equal, they must each owe 9$.
<h2>Answer</h2>
Each donor owes $9.
