Levi and Rachel performed an experiment in which they measured the heart rate of an average adult. On one day, Levi measured the resting heart rate of an adult. Then, the adult walked on a treadmill at a rate of four miles per hour. After thirty minutes, he measured the adult's heart rate again and recorded the data. Levi allowed the adult's heart rate to return to its original resting rate and then repeated his experiment two more times.

Two days later, Rachel performed the same experiment with the same adult. She, too, measured the resting heart rate and the heart rate after exercising. Their data appears below.

LEVI'S DATA RACHEL'S DATA

Resting Heart Rate = 62 bpm* Resting Heart Rate = 60 bpm*

Trial Heart Rate after Exercise

1 120 bpm

2 122 bpm

3 118 bpm

Trial Heart Rate after Exercise

1 118 bpm

2 119 bpm

3 120 bpm

* bpm = beats per minute

How do Levi and Rachel's results compare? pls help

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
