The following sentence maybe contain an appositive phrase. Draw one line under each appositive phrase and two lines under the word or words to which the phrase refers. If the sentence contains no appositive phrase, write None at the end of the sentence

The Museum of Science and Industry, located in Chicago's Hyde Park neighborhood, is near the University of Chicago.

Marie scored 95, 86, and 89 on three science tests. She wants her average score for 6 tests to be at least 90. What inequality can you write to find the average scores that she can get on her next three tests to meet this goal? Use s to represent the lowest average score.

The Latin root -frict- means "to break." A refractory animal is one that "breaks away." The root -fract-*appears in some scientific and mathematical terms, such as fraction. A fraction is a part "broken away" from a larger whole. Explain how the root -fract- contributes to the meaning of below italicized word.
Although her motives were good, she was guilty of an infraction of the law

As part of a science experiment, Greta measured the amount of water flowing from Container A to Container B. Container B had half a gallon of water in it to start the experiment. Greta found that the water was flowing at a rate of two gallons per hour. Which equation represents the amount of water in Container B? (A) y=2x, (B) y=0.5x, (C) y=2x+0.5, (D) y=0.5x+2

As part of a science project, you study traffic patterns in your city at an intersection in the middle of downtown. You set up a device that counts the cars passing through this intersection for a 24-hour period during a weekday. The graph of hourly traffics was discussed earlier.

At what time(s) does the highest number of cars pass through the intersection?

Biologists consider a species of animal or plant to be endangered if it is expected to become extinct within 20 years. If a certain species of wildlife is counted to have 1147 members at the present time, and the population has been steadily declining exponentially at an annual rate averaging 39% over the past 7 years, do you think the species is endangered? Explain your answer.

Jon found an organism in a pond, and he thinks it’s a freshwater sponge. His friend Liz thinks it looks more like an aquatic fungus. How can they decide whether it is an animal or a fungus?

a. See if it can swim.

b. Figure out whether it is autotrophic or heterotrophic.

c. See if it is a eukaryote or a prokaryote.

d. Look for cell walls under a microscope.

In a study of the reaction times of dogs to a specific stimulus, an animal trainer achieved the following data, given in seconds. Construct a histogram, a frequency polygon, and an ogive for the data; analyze the results.

Physiologists who study warm-blooded animals are interested in the basal metabolic rate, which is one measure of the energy needed for survival. It can be measured from the volume and composition of expired air. In the following table weight $W$, in pounds, of an animal and its basal metabolic rate $B$, in kilocalories per day. ${ }^{28}$ a. Find a formula that models $B$ as a power function of $W$. b. Describe the metabolic weight of a warm-blooded animal to be $W^{0.75}$ if $W$ is its weight in pounds. Direct comparison of food among animals of different sizes is not easy. Clearly, large animals will consume more food than small ones, and to compensate for this, we should take account of the energy needed for survival-that is the basal metabolic rate $B$. To compare the maximum daily food intake among animals of different sizes, we divide this food intake by the metabolic weight.

$$\begin{array}{|l|c|c|} \hline \text { Animal } & \text { Weight } W & \begin{array}{c} \text { Basal metabolic } \\ \text { rate } B \end{array} \\ \hline \text { Rat } & 0.38 & 20.2 \\ \hline \text { Pigeon } & 0.66 & 30.8 \\ \hline \text { Hen } & 4.3 & 106 \\ \hline \text { Dog } & 25.6 & 443 \\ \hline \text { Sheep } & 101 & 1220 \\ \hline \text { Cow } & 855 & 6421 \\ \hline \end{array}$$

Mr. Alim's science class launched a toy rocket from ground level with an initial upward velocity of 60 feet per second. The height $h$ of the rocket in feet above the ground after $t$ seconds is modeled by the equation $h=60 t-16 t^2$. How long was the rocket in the air before it returned to the ground?

A science museum has a display called a sewer pipe symphony. It consists of many plastic pipes of various lengths, which are open on both ends. (a) If the pipes have lengths of $3.0 \mathrm{~m}, 2.5 \mathrm{~m}$, $2.0 \mathrm{~m}, 1.5 \mathrm{~m}$ and $1.0 \mathrm{~m}$, what frequencies will be heard by a visitor's ear placed near the ends of the pipes?

The following exercise involves distinguishable permutations.

A group of thirty students is taking a field trip to a science museum. Three vans are available for transporting the students. The first van has room for eight students, and the other two vans each have room for eleven students. In how many different ways can the students be assigned to the vans?

As part of a science project, you study traffic patterns in your city at an intersection in the middle of downtown. You set up a device that counts the cars passing through this intersection for a 24-hour period during a weekday. The graph of hourly traffics was discussed earlier.? c. Briefly describe the trend in the number of cars over the course of the day.

The following formulas give animal populations as functions of time, t, in years. Describe the growth of each population in words.

(a) $P=1500+200 t$

(b) $P=2700-80 t$

(c) $P=1800(1.03)^t$

(d) $\quad \mathrm{P}=800 e^{-0.04 t}$

(e) $P=230 \sin \left(\frac{2 \pi}{7} t\right)+3800$
