Answer:
A self esteem can be defined as how you value yourself or how much do you value yourself. Some may feel that they are inferior to others, which shows that they do not value themselves. To improve one's self esteem, he/she must have self-respect. If you respect yourself, it makes others want to respect you, which persuades you to value yourself. Being confident of one self and the belief that '' I can do it'' makes a person value himself more. Having self esteem not only upgrades you, but also improves you by giving various chances and giving you a feeling to create various choices you have never made before. Believing that, even if you have your own demerits, you also have merits making others want to applaud for you also help you to favor yourself more.

Answer:
Mary's target heart rate is 103 beats per minute (bpm).
Explanation:
The maximum heart rate (MHR) is the rate at which the human heart of a given person reaches the highest demands. At rest, the heart rate is about 60 to 80 beats per minute.
MHR = 220 - age
So, for Mary: MHR = 220 - 14 = 206 beats per minute (bpm)
Now we can calculate Mary's target heart rate:
Target heart rate = MHR * 50% = 206 * 0.5 = 103 beats per minute (bpm)
Hope this helped!
