Answer:
The product mass function is calculated taking different values of x=1,2,3,4.....
Step-by-step explanation:
using trig, tangent is equal to opposite over adjacent.
in this case, the angle is 45, opposite is 7, and adjacent is a.
thus tan 45° = 7/a
solve for a to get a = 7/tan 45° = 4.32
Line up the decimal point to each number in order from left to right and subtract to get the difference which should be -0.248
The answer to the question is
5r= 28
r= 28/5
