3/5 times. in reality it should have landed 250 times as in an ideal world you get 50/50 odds of getting one side or the other

john invested $2000 that earn interest at 4% per annum compounded monthly. two year later the interest rate is 4.50% compounded

Ksju [112]

Answer:

$\$2,369.11$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

Part 1)

$t=2\ years\\ P=\$2,000\\ r=0.04\\n=12$

substitute in the formula above

$A=2,000(1+\frac{0.04}{12})^{12*2}$

$A=2,000(1.0033)^{24}$

$A=\$2,166.29$

Part 2)

$t=2\ years\\ P=\$2,166.29\\ r=0.045\\n=4$

substitute in the formula above

$A=2,166.29(1+\frac{0.045}{4})^{4*2}$

$A=2,166.29(1.01125)^{8}$

$A=\$2,369.11$

Can someone please help me !?!??!

The perimeter is just the sum of all the side lengths, so you have

$P=2.8+3.4+10.8+7.1+4.5+8.2=36.8$
