Answer: C) 0.161</h3>
===========================================================
Explanation:
Add up the number of rings of each color:
11+15+0+5 = 31
We have 31 rings total. Of this total, we have 5 yellow.
This means the theoretical probability of getting yellow is approximately 5/31 = 0.161
This is roughly a 16.1% chance.
The first fraction is saying that 12 cups over 3 dollars is equal to 9 dollars over however many cups. To make it correct it would be 12/3 = C/9.
Angle a is directly opposite from a 40 degree angle, so a=40. Then we can find b since the sum of the angles of all triangles is 180 and there is a right angle in there along with angle a:
Last, to find c we just notice that it is supplementary with an angle of measure 65, so:
So our angles are a=40, b=50, c=115.
Answer:
14,181
Step-by-step explanation:
Let the total population of seal pups =p
Ratio of Tagged to Total seal pups observed is given as:
200:600
Population of Tagged to Total Population therefore is:
4727: p
Equating both ratios
200:600=4727:p
200/600=4727/p
200 X p= 4727 X 600
p = (4727 X 600)/200
p=14,181
The total population of fur seals pups is 14,181
