Find how long it takes a $ 900.00 investment to earn $ 120.00 in interest if it is invested at 6% compounded annually.

atroni [7]

So, we know the earned interest is 120, and we know the original deposited amount is 900 bucks, so, the accumulated amount will then be 900 + 120 or 1020 bucks.

$\bf \qquad \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\to &\$1020\\
P=\textit{original amount deposited}\to &\$900\\
r=rate\to 6\%\to \frac{6}{100}\to &0.06\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{annually, thus once}
\end{array}\to &1\\
t=years
\end{cases}$

$\bf 1020=900\left(1+\frac{0.06}{1}\right)^{1\cdot t}\implies \cfrac{1020}{900}=(1.06)^t\implies \cfrac{102}{90}=(1.06)^t
\\\\\\
log\left(\frac{102}{90} \right)=log(1.06^t)\implies log\left(\frac{102}{90} \right)=t\cdot log(1.06)
\\\\\\
\cfrac{log\left(\frac{102}{90} \right)}{log(1.06)}=t\implies 20.92 \approx t$

The manager of a warehouse would like to know how many errors are made when a product’s serial number is read by a bar-code read

goblinko [34]

Answer:

Mean=20.5

standard deviation=13.28

Step-by-step explanation:

We are given six samples i.e.

36, 14, 21, 39, 11, and 2

Mean is the average of all the samples

Mean= sum of all samples/no. of samples

Mean=(36+14+21+39+11+2)/6

Mean=20.5

Standard deviation is the positive square root of variance where

variance= sum of square of samples/number of samples-(mean)²

variance=(36²+14²+21²+39²+11²+2²)/6-(20.5)²

= 596.5-420.25

= 176.25

standard deviation= √(176.25)

standard deviation= 13.28
