Sales tax is an additional amount of money you pay based on a percentage of the selling price of goods and services that are purchased. For example, if you purchase a new television for $400 and live in an area where the sales tax is 7%, you would pay $28 in sales tax. Your total bill would be $428.88
F(g(7))= f(2×7+2)= f(16)= 4×16+21=85
Therefore: the answer is 85
Hope that helps!!
To get the required value of the missing probability to
make the series complete is to deduct all the probability given to 1 because we
know that the discrete probability distribution must be equal to 1. So doing
what I have said, this will be:
P(4) = 1 - P(3) - P(5) - P(6)
= 1 – 0.3 – 0.18 – 0.21
<span>= 0.31 is the answer.</span>
