Circle the BEST answer.
A person's $SpO_{2}$ is 98%. Which is true?
a The person's pulse oximeter is wrong.
b The pulse is 98 beats per minute.
c The measurement is within normal range.
d The person has respiratory depression.

Vital Signs
Blood pressure (BP) 152/84mm Hg
Pulse rate 124 beats/min
Respiratory rate 42 breaths/min
Temperature 100.4 F (38.4 C)
Are B.T.'s vital signs acceptable? State your rationale.

Decide whether each of the following statement is true or false. Explain your reasoning. I graphed a function showing how my heart rate depends on my running speed. The domain was heart rates from $60$ to $180$ beats per minute.

Vital Signs
Blood pressure (BP) 152/84mm Hg
Pulse rate 124 beats/min
Respiratory rate 42 breaths/min
Temperature 100.4 F (38.4 C)
What is the rationale for immediately starting B.T. on 02 ?

Bob beats Judy by $10$ m in a $100$-m dash. Bob, claiming to give Judy an equal chance, agrees to race her again but to start from $10$ m behind the starting line. Does this really give Judy an equal chance?

The hummingbird has an average wing speed of $70$ beats per second. The expression $70 t$ gives the number of wingbeats in $t$ seconds.

Calculate the number of wingbeats in $1$ minute. (Hint: How many seconds are in $1$ minute?)

A shrew, the world's smallest mammal, has a heart rate of 790 beats per minute. About how many times does a shrew's heart beat in 5 minutes?

$$F. \ 3,500 \\ G. \ 4,000 \\ H. \ 4,500 \\ J. \ 4,790$$

Two strings are adjusted to vibrate at exactly 200 Hz. Then the tension in one string is increased slightly. Afterward, three beats per second are heard when the strings vibrate at the same time. What is the new frequency of the string that was tightened?

Nontransitive dice. In this problem we consider three dice with unusual numbering. Call the three dice 1, 2, and 3. The spots on the three dice are given in the following chart. Die 1: 5, 6, 7, 8, 9, 18 Die 2: 2, 3, 4, 15, 16, 17 Die 3: 1, 10, 11, 12, 13, 14 A game is played with these dice. Each player gets one of the dice (and the two players have different dice). They each roll their die, and whoever has the higher number of wins. a. If dice 1 and 2 are rolled, what is the probability that die 1 beats die 2? b. If dice 2 and 3 are rolled, what is the probability that die 2 beats die 3? c. If dice 3 and 1 are rolled, what is the probability that die 3 beats die 1? d. Which die is best?

Two loudspeakers emit 400 Hz notes. One speaker sits on the ground. The other speaker is in the back of a pickup truck. You hear eight beats per second as the truck drives away from you. What is the truck’s speed?

It is not uncommon after a round of golf to find a foursome in the clubhouse shaking the bar dice to see who buys the refreshments. In the first two rounds, each person gets to shake the five dice once. The person with the most dice with the highest number is eliminated from the competition to see who pays. So, for instance, four 3s beats three 5s, but four 6s beats four 3s. The 1s on the dice are wild, that is, they can be used as any number. a. What is the probability of getting five 6s? (Remember 1s are wild.) b. What is the probability of getting no 6s and no 1s?

Two identical mandolin strings under $200 \mathrm{~N}$ of tension are sounding tones with frequencies of $523 \mathrm{~Hz}$. The peg of one string slips slightly, and the tension in it drops to 196 N. How many beats per second are heard?

Find mean, median, mode, and range. Which measure of central tendency best describes each group of data? Explain. resting heart rate in beats per minute: 79 72 80 81 40 72

Suppose that the target heart rate, $H$, in beats per minute, for your exercise goal is given by

$$H=\frac{4}{5}(220-a),$$

where $a$ is your age. If you are $30$ years old, what is your target heart rate?
