The average
The data whose average is to be calculated are not given.
However, the formula to calculate the average is:
Assume the data is:
This means that the number of schools is 4
So:
<em>The average of the assumed data is 1238</em>
The answer is x=2. You add 6x to both sides to get 7x-9=5 then add 9 to both sides to get 7x=14. From there, you divide by 7 on both sides to get x=2.

Greetings !
simplify for variable y first
apply exponent rule
Add/subtract the numbers -8+3=5
Apply exponent rule
Thus,
secondly, simplify for the variable x
Apply exponent rule as we made on y
multiply bot the values we get
Hope it helps!

Answer:
13.86
Step-by-step explanation:
formula for cont. compounding interest is
Amount = Principal * e^rt
in this case the principal is 5000, and the amount is 10000 (double). the rate is 5% or 0.05. and t is what we are solving for.
sub in to get:
10000 = 5000e^0.05t
2 = e^0.05t
now convert to log form.
ln 2 = 0.05t
ln 2 / 0.05 = t
punch that into your calculator and you get 13.86 years
