The critically endangered Maui’s dolphin is currently restricted to a relatively small stretch of coastline along the west coast of New Zealand’s North Island. The dolphins are “captured” by just collecting samples of DNA and “tagged” by identifying their DNA fingerprint. A 2010-2011 capture-recapture study “captured” and “tagged” 26 Maui’s dolphins in 2010. In 2011, 27 Maui’s dolphins were “recaptured” and through their DNA, 12 were identified as having been “tagged” in 2010. Based on these figures, estimate the population of Maui’s dolphins in 2011.

The garden and a walkway around its perimeter have an area of 690 square feet. Find the width of the walkway (x) if the garden measures 14 feet wide by 18 feet long. Write answer to 2 decimal places. (Write the number without units). Hint: add 2x to each of the garden dimensions of 14 x 18 feet to get the total area for the length multiplied by width.arrow_forward
