Answer:
$3027.80
Explanation:
The compound interest formula is the following.

where
A = final amount
P = principle amount
r = interest rate / 100
n = number of compounds per interval
t = time interval
Now in our case,
A = unknown
P = $1900
r = 10.4/100
n = 12 months / year ( because the interest is compounded monthly)
t = 4.5 yrs
Therefore, the compound interest formula gives

Using a calculator, we evaluate the above to get

which is our answer!
Answer:
k = 3.5
Step-by-step explanation:
You need to divide all the numbers.
21/6 = 3.5
24.5/7 = 3.5
28/8 = 3.5
31.5/9 = 3.5
So, the answer is 3.5.
Answer: what is wrong with it
Step-by-step explanation:
The correct answer is 2– it is NOT a possible value for correlation coefficient (r) because the value of “r” must always be between +1 and –1.
