Answer:
17160
Step-by-step explanation:
Total number = n = 13
Number required = r= 4
If the number required does not have a specific order then combinations is chosen.
If a specific arrangement is required then permutations is used.
Here a specific arrangement is mentioned therefore
13P4= 17160

119.99 - 71.99 = 48.00 is 40%
53.3
34^2=1156

1156+1681=2837
Square root of 2837 is 53.26 which rounded to the nearest tenth is 53.3
