Answer:
0.33
Step-by-step explanation:
We would like to find the probability that both beads are aqua.
There are 6 aqua beads. Let's calculate the number of ways we can select 2 aqua beads from these 6. We use combinations, which is , where the n! means n * (n - 1) * (n - 2) * ... * 2 * 1.
The value of the expression is:
So there are 15 ways to choose 2 aqua beads.
Now let's calculate the number of ways we can select any 2 beads. There are 6 + 4 = 10 beads in total, so we do the same thing as before using combinations:
Our fraction is thus:
15 / 45 = 1/3 ≈ 0.33
The answer is thus 0.33.

Answer:
y=5/17x+17 3/17
Step-by-step explanation:
put the points on slope to get 5/17. then use point slope form (y-y1)=m(x-x1) and plug in 41 for x1, 81 for y1, and 5/17x for m
Answer:
c = -13a
Step-by-step explanation:
5a + c = -8a
-5a -5a
c = -13a

15, 26, 48, 92, 180
26 - 15 = 13
48 - 26 = 22
92 - 48 = 44
180 - 92 = 88
26 ÷ 15 = 1.73
48 ÷ 26 = 1.84
92 ÷ 48 = 1.9167
180 ÷ 92 = 1.95
