Answer:

There are 924 possible combinations

Step-by-step explanation:

Total Number of marbles = 12

Number of marbles to be selected = 6

We are supposed to find the number of possible combinations .

So, we will use combination .

Formula: $^nC_r =\frac{n!}{r!(n-r)!}$

n = 12

r = 6

Substitute the values in the formula :

$^{12}C_6 =\frac{12!}{6!(12-6)!}\\^{12}C_6 =\frac{12!}{6!6!}\\^{12}C_6 =924$

Hence there are 924 possible combinations

You decide to put $5000 in a savings account to save $6000 down payment on a new car. If the account has an interest rate of 7%

$\bf ~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\dotfill&\$6000\\ P=\textit{original amount deposited}\dotfill &\$5000\\ r=rate\to 7\%\to \frac{7}{100}\dotfill &0.07\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{monthly, thus twelve} \end{array}\dotfill &12\\ t=years \end{cases}$

$\bf 6000=5000\left(1+\frac{0.07}{12}\right)^{12\cdot t}\implies \cfrac{6000}{5000}\approx (1.0058)^{12t}\implies \cfrac{6}{5}\approx(1.0058)^{12t} \\\\\\ \log\left( \cfrac{6}{5} \right)\approx \log[(1.0058)^{12t}]\implies \log\left( \cfrac{6}{5} \right)\approx 12t\log(1.0058) \\\\\\ \cfrac{\log\left( \frac{6}{5} \right)}{12\log(1.0058)}\approx t\implies 2.63\approx t\impliedby \textit{about 2 years, 7 months and 16 days}$
