We assume that females have pulse rates that are normally distributed.
Then , the formula to calculate the z-score is given by :-

For x =69

For x= 77

The p-value =

Hence, the probability that her pulse rate is between 69 beats per minute and 77 beats per minute =0.2510
You need to represent it as 2x + 10 = 50
