Answer:

19/67

Step-by-step explanation:

I think this would be the answer. You add up 17,10,19, and 21, and then use the PROBABILITY of drawing the nickels which would be 19/67, im not sure tho, let me know if it works

An account earns simple interest. Find the interest earned. $1200 at 2.8% for 30 months
sasho [114]

let's bear in mind that a year has 12 months, so 30 months is really 30/12 years.


\bf ~~~~~~ \textit{Simple Interest Earned}
\\\\
I = Prt\qquad
\begin{cases}
I=\textit{interest earned}\\
P=\textit{original amount deposited}\dotfill & \$1200\\
r=rate\to 2.8\%\to \frac{2.8}{100}\dotfill &0.028\\
t=years\to \frac{30}{12}\dotfill &\frac{5}{2}
\end{cases}
\\\\\\
I=(1200)(0.028)\left( \frac{5}{2} \right)\implies I=84

An after school music program has 15 out of 50 students participating. Write 1550 as a decimal and as a percent. Decimal- Percen
yarga [219]

Answer:

0.3

30%

Step-by-step explanation:

To write 15/50 as a percent, you have to multiply the fraction by 100

\frac{15}{50} x 100

dividing 100 by 50 gives 2

15 x 2 = 30%

to convert 15/50 to a decimal, first simply the fraction.

Both the numerator and denominator can be divided by 5

3/10

the next step is to divide the numerator by the denominator

3/10 = 0.3
