Question

step 10: determine the sizes of the flocks in the second generation

• divide each flocks total pieces of food by 300, the total number of pieces of food eaten.

** multiply the food percentage for each flock by the total number of birds (30).

Explanation:

Step1: Calculate food percentage

For Flock X: $\frac{57}{300}\times100 = 19\%$
For Flock Y: $\frac{153}{300}\times100 = 51\%$
For Flock Z: $\frac{90}{300}\times100 = 30\%$

Step2: Calculate simulated number of birds

For Flock X: $0.19\times30 = 5.7\approx6$
For Flock Y: $0.51\times30 = 15.3\approx15$
For Flock Z: $0.30\times30 = 9$

Answer:

Food Percentage: Flock X - $19\%$, Flock Y - $51\%$, Flock Z - $30\%$; Simulated Number of Birds: Flock X - $6$, Flock Y - $15$, Flock Z - $9$
