A back-to-back stemplot for life expectancies of males and females in the nations of South America (Round to nearest year and use split stems.)

An interstellar space probe is launched from Earth. After a brief period of acceleration, it moves with a constant velocity, 70.0% of the speed of light. Its nuclear-powered batteries supply the energy to keep its data transmitter active continuously. The batteries have a lifetime of 15.0 years as measured in a rest frame. How far is the probe from Earth as measured by its built-in trip odometer when its batteries fail?

The average distance between Mars and Earth is about $1.3 \times 10^8$ miles. How long would it take TV pictures transmitted from the Viking space vehicle on Mars' surface to reach Earth? ( $1$ $\mathrm{mile}=1.61 \mathrm{~km}$.

Look at the drawings below of environmental problems and their solutions. Describe how each one affects the environment. Write two complete sentences for each. Follow the model. Modelo: Hay mucho humo que causa la contaminación del aire. Es un problema grave para el pueblo. _____

The midterm exam in a nursing course consists of 75 true/false questions. Imagine that an unprepared student makes random guesses for the answers.

b. Would it be unusual for a student to pass this exam by guessing and getting at least 45 correct answers? Why or why not?

The hormone prolactin, which stimulates milk production in a nursing mother, is produced by the ______. A. adrenal gland, B. ovaries, C. pituitary gland, D. thyroid gland.

Environmental scientists measure the intensity of light at various depths in a lake to find the "transparency" of the water. Certain levels of transparency are required for the biodiversity of the submerged macrophyte population. In a certain lake the intensity of light at a depth of $x$ feet is given by

$$I=10 e^{-0.008 x}$$

where $I$ is measured in lumens. At what depth has the light intensity dropped to 5 lumens?

What role might H. ergaster have played in the evolution of modern humans according to the replacement model?

Distance to the earth From an exterior point $P$ that is $h$ units from a circle of radius $r$, a tangent line is drawn to the circle. Let $y$ denote the distance from the point $P$ to the point of tangency $T$. If $r$ is the radius of the earth and $h$ is the altitude of a space shuttle, then $y$ is the maximum distance to the earth that an astronaut can see from the shuttle. In particular, if $h=200 \mathrm{mi}$ and $r \approx 4000 \mathrm{mi}$, approximate $y$.

Nursing supervisors are selected using random numbers to determine annual salaries. Classify each sample as a random, systematic, stratified, cluster, or other.

In March $2004$, the European Space Agency launched the Rosetta spacecraft, whose mission was to deliver the Philae lander to explore comet $67$P/Churyumov-Gerasimenko. The lander finally arrived on the comet in late $2014$. This comet is currently more than $320,000,000$ miles from Earth. Write $320,000,000$ in scientific notation.

How does the nursing department at University Hospital represent how businesses frequently respond to deliberate organisational change? Are there any ways that the nature of the change—or the manner in which University Hospital is implementing it—differ from customary practises?
