For her exercise today, amy plans to both run and swim. let r be the number of laps she runs and let s be the number of laps she swims. each lap she runs takes her 4 minutes, and each lap she swims takes her 2 minutes. she wants to exercise for at least 40 minutes today. using the values and variables given, write an inequality describing this.

1.  Let r be the number of laps she runs. If each lap she runs takes her 4 minutes, then r laps take her 4r minutes.

2. Let s be the number of laps she swims. If each lap she swims takes her 2 minutes, then s laps take her 2s minutes.

3. In total she will exercise 4r+2s minutes.  You know that Amy wants to exercise for at least 40 minutes today, therefore,

4r+2s≥40.

4r+2s≥40.

boxplot e is the answer

homozygous. one is homozygous, while two is heterozygous.
