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

What is the rate of change for 2y+3=3x
Elenna [48]
The rate of change in z at (4,9) as we change x but hold y fixed is = 3/[2sqrt(3x+2y)] put x = 4 , y = 9 = 3/[2sqrt(12+18) = 3/[2sqrt(30)] The rate of change in z at (4,9) as we change y but hold x fixed is = 1/sqrt(3x+2y) put x = 4, y =9 = 1/sqrt(30)

the ratio of the length of an airplane wing to its width is 7 to 1. find the length of wing is 26.7 meters, how wide must it be?
maw [93]
If the ratio is 7 to 1, the width of the wing must be 1/7 of the length. So, we just divide 26.7 by 7 to get 3.81 meters.
