Answer:
5
Step-by-step explanation:
To find the mean add up all the numbers
4+ 3+ 4+ 5+ 6+ 6+ 8+ 4=40
Then divide by the number of terms
There are 8 terms
40/8 = 5
The mean is 5
Answer:
For part 6: 39
Step-by-step explanation:
You have your starting number and then it gets added to a product of two numbers. 8 + (2x2) = 12. 12 + (2x3) = 18. 18 + (3x3) = 27. 27 + (3x4) = 39. That is the most logical answer I was able to find.
The Federal Insurance Contributions Act (FICA) is made up of
two items, Social Security and Medicare taxes. For 2016, the Social Security
tax rate is 6.2% on the first $118,500 wages paid. The Medicare tax rate is
1.45% on the first $200,000 and 2.35% above $200,000. Since the total earnings is
only $110,700 which is not yet taxable. So there is no taxable earnings yet.
Answer:
3/4x-6=42
x=64
Step-by-step explanation:
Let the number of students be x hence 3/4 of this number will be 3/4x
Since the number was 42 if they were 3/4x less six, it means minus six hence
3/4x-6=42
Therefore, the equation will be
3/4x-6=42
Solving the equation
3/4 x=42+6=48
3/4x=48
X=62
Answer:
=209.09 mg
Step-by-step explanation:
given: material= radium
half life= 1590 years
initial mass 
=500mg
we know that to calculate the amount left we use
= 
therefore
= 
=209.09058407921 mg
=209.09 mg amount left after 2000 years
