To measure the population density of monarch butterflies occupying a particular park, 100 butterflies are captured, marked with
Sav [38]

Answer:

Given merely 40 butterflies were marked, assumed that there were multiple captures of both marked and unmarked butterflies, that the butterflies caught in traps were on the loose to be caught again. There are two mathematical solutions for this, both yielding the same answer which is 100. 

• First, to each marked butterfly was taken twice (40 marked X2 = 80 captured) then of the unmarked butterflies the 120 captured must relate to 60 actual butterflies. In which 40 + 60 = 100. 

• Secondly, by means of ratios in which 80/200 = 40/X. In this case X also = 100 that will result to the estimated size of the population of wilson park is 100.

4. A wave traveling at 200 m/sec has a wavelength of 2 meters. What is the
dalvyx [7]

Given that,

The speed of a wave, v = 200 m/s

Wavelength, \lambda=2\ m

We need to find the frequency of this wave. The relation between wavelength, frequency and the speed is given by :

v=f\lambda\\\\f=\dfrac{v}{\lambda}\\\\f=\dfrac{200\ m/s}{2\ m}\\\\f=100\ Hz

So, the frequency of this wave is 100 Hz.
