An island has 12 fur seal rookeries (breeding places). to estimate the fur seal pup population in rookery a, 6334 fur seal pups were tagged in early august. in late august, a sample of 1200 pups was observed, and 205 of these were found to have been previously tagged. use a proportion to estimate the total number of fur seal pups in rookery a.

37080

Step-by-step explanation:

To solve this problem we need to use proportions:

We don't know the total population in Rookery A but we know that 6334 of the total were tagged. Later, from a sample of 1200 pups, 205 were previously tagged.

The proportions we get are:

where p is the total population.

Now we will solve the proportion for p:

Therefore the total number of fur seal pups is 37077 ≈ 37080

25.2

step-by-step explanation:

2+4x6-8/10= 25.2

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
