Answer: D) 43.1

<u>Step-by-step explanation:</u>

$\dfrac{\text{Volume of box }}{ \text{ number of apples}}\\\\\\\dfrac{20\ in\times 13\ in\times 12\ in}{72\ apples}=43.3\ in^3\ per\ apple\\\\\\\dfrac{12\ in\times 12\ in\times 12\ in}{40\ apples}=43.2\ in^3\ per\ apple\\\\\\\\\dfrac{20\ in\times 10\ in\times 6\ in}{28\ apples}=42.9\ in^3\ per\ apple$

Now find the average:

$\dfrac{43.3+43.2+42.9}{3}\quad =43.1$

Answer: Our required probability is 0.1695.

Step-by-step explanation:

Since we have given that

Number of male applicants = 4200

Number of female applicants = 3800

So, total number of applicants = 4200+3800 = 8000

Probability of male entered and subsequently enrolled is given by

$0.4\times 0.4=0.16$

Probability of female entered and subsequently enrolled is given by

$0.4\times 0.45\\\\=0.18$

Number of male entered and subsequently enrolled is given by

$0.16\times 4200\\\\=672$

Number of female entered and subsequently enrolled is given by

$0.18\times 3800\\\\=684$

So, Probability that a student who applied for admission will be accepted by the university and subsequently will enroll is given by

$\dfrac{672+684}{8000}\\\\=\dfrac{1356}{8000}\\\\=0.1695$

Hence, our required probability is 0.1695.

Nicole deposited $2,000 at 6% simple interest. How long will it be before she has $2,600 in her account?

coldgirl [10]

$\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\to &2,600\\
P=\textit{original amount deposited}\to& \$2,000\\
r=rate\to 6\%\to \frac{6}{100}\to &0.06\\
t=years
\end{cases}$

solve for "t"
