Answer:
$1,577.74
Step-by-step explanation:
You are going to want to use the continuous compound interest formula, which is shown below.

<em>A = total
</em>
<em>P = principal amount
</em>
<em>r = interest rate (decimal)
</em>
<em>t = time (years)
</em>
<em />
First change 3% to its decimal form:
3% ->
-> 0.03
Next, we can plug in the values into the equation:


The last step is to subtract 8,000 from 9,577.74:

The total interest earned is $1,577.74
Answer:
1 and idk the second

Hello from MrBillDoesMath!
Answer:
tan ^(-1) (6/7), the last expression in the list
Discussion:
In a right triangle,
tan(@) = side opposite angle\side adjacent to angle.
In our triangle, this becomes
tan(@) = LM \ MN = 6/7 =>
@ is the inverse tangent of (6/7)

Step-by-step explanation:
To figure out the variance, subtract 82.5 from the mean, which is 5.5 and then divide by N, which is the value of numbers, (in this case 10) minus 1. The result is a variance of about 9.17. Standard deviation is the square root of the variance so that the standard deviation would be about 3.03.Calculate the mean.
Subtract the mean from each observation.
Square each of the resulting observations.
Add these squared results together.
Divide this total by the number of observations (variance, S2).
Use the positive square root (standard deviation, S).
