From the 8 digits; the first must be nonzero (i.e. any of 1 - 9).
There are 9 ways of selecting this:
The other 7 digits could be any of the 10 digits and there may be repetition.
Each of the digits can be selected in 10 ways. So, the number of ways of selecting the 7 digits is: 
<u>For the alphabets:</u>
The first can be selected from the

Answer: option d= 130 - 150.
Explanation:
From the question, we are given that the man's age= 50, the man weighs= 193 lb (87.5 kg) and the 50 years old man's resting heart rate= 70 beats · min-1. Then, I am asked to calculate the man's target heart rate (THR) zone for 60% to 80%.
Using the Karvonen (HRR) method to calculate the fifty(50) years old man's target heart rate (THR) zone for 60% to 80%, we will need the man's age for this Calculation and the man's resting heart rate (HR).
Important information to note that is not given from the question is that the 50 years old man's estimated maximum heart rate is (220 - 50) = 170.
Step one: Using the formula; maximum heart rate - man's age × zone Percent. --------------------------(1).
Step two: equation (1) + resting heart rate (HR). -------------------------(2).
For the 60 percent = 0.6.
==>( 170 - 70) × .6 = 60.
Then, 60 + 70 = 130.
For the 80 percent= 0.8;
==> (170 - 70) × .8 = 80.
Then, 80 + 70 = 150.
