Answer:
n = -1
Step-by-step explanation:
n - 2 = 1/2 (10n+4) // We have the equation.
n - 2 = 5n + 2 // Solve the righ side.
n - 5n = 2 + 2 // Group common terms.
-4n = 4 // Solve.
n = -4/4
n = -1
The answer for the function F(4) = 5/81
<u>Step-by-step explanation</u>:
The given function is F(x) = 5 * (1/3) ^ x
<u>step 1</u> :
The x value is given as the input to get the output from F(x)
<u>step 2</u> :
Here, F(4) means that the x value is x=4
<u>step 3</u> :
Now, substitute x=4 in the given function F(x)
F(4) = 5 (1/3)^4
=5 (1/81)
F(4) = 5/81
30 candles=100%
30% of 100%= 9 candles out of 100 candles
after blowing out 30% of the candles, 9 should be left lit.
Answer:
the mean is 8 and the absolute deviation is 1.5
Step-by-step explanation:
to find the mean you add up all the numbers, then you just divide by how many numbers there are. in this case, you would do 64/8 which would then equal 8. then you see how much the numbers differ from the mean. like for your numbers, for 8 it would be 0, for 9 it would be 1, for 7 it would be 1, for 6 it would be 2. you see it? its just how far away it is from the mean. so once you do that, you should have a 6. then you do 6/4 which is 1.5. hope this helps!
He earned $820 but is left with $683.20.
820.00 - 683.20 = $136.80 is taken away
From this $136.80 taken away, $95.60 was federal income tax. Subtract $95.60 from $136.80.
136.80 - 95.60 = $41.20
Your answer is D.
