Answer:
The sales tax is $19.80
The total cost is $349.80
Step-by-step explanation:
To find the sales tax, multiply 330 by 0.06 (6%)
To find the total cost add the sales tax, 19.80 with 330
3+2+8
3+2=5
5+8=13
so,13 is the correct answer
Just work this problem out backwards. First write out an equation.
(x+4)•3=30
Now solve :
(x+4)•3=30
3x+12=30
-12 -12
3x=18
/3 /3
x=6
Your answer is 6!

Answer: So the number of outcomes with exactly 4 tails is 720/2/24 = 15. Finally we can now calculate the probability of getting exactly 4 tails in 6 coin tosses as 15/64 = 0.234 to 3 decimal places.
