Answer:
I = $ 480.00
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year,
then, solving our equation
I = 4000 × 0.06 × 2 = 480
I = $ 480.00
The simple interest accumulated
on a principal of $ 4,000.00
at a rate of 6% per year
for 2 years is $ 480.00.
Answer:
3.74
Step-by-step explanation:
The standard deviation for this question is 3.74. I found this by going to an online graphing calculator, I use GeoGebra Graphing Calculator and insert the numbers. Before you type them though, you have to put SD (this stands for standard deviation, and yes it MUST be capitalized.) Then insert the points into a set of parentheses and press enter. Like so:
SD(42, 54, 50, 42, 46, 46, 48, 48) = 3.74165
Usually, your instructor will only want you to round two decimal places so the rest of the deviation is not needed or important unless you have to round up.
I hope this helped. :)
27/35 is the greatest factor
Answer:
d) $8,100
Step-by-step explanation:
Given information:
- Money triples every 10 years
- Initial deposit = $100
- Number of years invested = 40 years
If the money triples (multiplies by 3) every 10 years,
then in 40 years time it will triple <u>4 times</u>, as 40 ÷ 10 = 4
⇒ Account balance after 40 years = $100 × 3 × 3 × 3 × 3
= $100 × 3⁴
= $8,100
<u>Proof</u>
In 10 years time the balance of the account will be:
$100 x 3 = $300
In another 10 years time, the balance of the account will be:
$300 x 3 = $900
In another 10 years time, the balance of the account will be:
$900 x 3 = $2700
In another 10 years time, the balance of the account will be:
$2700 x 3 = $8100
