A binomial experiment is given. Determine whether you can use a normal distribution to approximate the binomial distribution. If you can, find the mean and standard deviation. If you cannot, explain why. In a recent year, alcohol-impaired driving was the cause of 31% of motor vehicle fatalities. You randomly select 30 motor vehicle fatalities and determine whether alcohol-impaired driving was the cause.

Optical engineers need to know the cone of acceptance of an optical fiber. This is the maximum angle that an entering light ray can make with the axis of the fiber if it is to be guided down the fiber. What is the cone of acceptance of an optical fiber for which the index of refraction of the core is 1.55 while that of the cladding is 1.45? You can model the fiber as a cylinder with a flat entrance face.

Find the required horizontal and vertical components of the given vectors.
A car is being unloaded from a ship. It is supported by a cable from a crane and guided into position by a horizontal rope. If the tension in the cable is $2790 \mathrm{lb}$ and the cable makes an angle of $3.5^{\circ}$ with the vertical, what are the weight $W$ of the car and the tension $T$ in the rope? (The weight of the cable is negligible to that of the car.)

If for a given vehicle it takes 20 hp to overcome aerodynamic drag while being driven at 65 mph, estimate the horsepower required at 75 mph.

A large vehicle in Fig. is slowed by lowering a $\textrm{2-m}$-wide scoop into a reservoir of water. Estimate the force exerted on the scoop if the vehicle is traveling at $60 \mathrm{~m} / \mathrm{s}$ and it scoops off $5 \mathrm{~cm}$ of water? The scoop diverts the water through $180^{\circ}$. (A) $720~\mathrm{kN}$ (B) $360 ~\mathrm{kN}$ (C) $12 ~\mathrm{kN}$ (D) $7.2 ~\mathrm{kN}$

Data Analysis The table shows the numbers $y$ (in millions) of motor vehicle registrations in the United States for the years $1997$ through $1999.$

$$\begin{array}{|c|c|} \hline \text{Year},t & \text{Registration},y\\ \hline 1997 & 207.8 \\ 1998 & 211.6 \\ 1999 & 216.3 \\ \hline \end{array}$$

Use the result of the previous Exercise to estimate when the number of vehicle registrations will reach $240$ million.

Choose the answer that best describes the action or situation.
___________ Something that tells a driver to proceed
a. parked vehicle
b. crosswalk
c. green light
d. ambulance

The more aerodynamic a vehicle is, the less fuel the vehicle’s engine must use to overcome air resistance. To design vehicles that are as fuel efficient as possible, automotive engineers use the formula R =0.00256 $\times D_C \times F_A \times s^2$ where R is the air resistance (in pounds), $D_C$ is the drag coefficient, $F_A$ is the frontal area of the vehicle (in square feet), and s is the speed of the vehicle (in miles per hour). The formula assumes that there is no wind. Find the drag coefficient of a car when the air resistance is 50 pounds, the frontal area is 25 square feet, and the speed of the car is 45 miles per hour.

For the fleet described in Exercise 2.48,

b. Construct a cross-tabulation describing the fleet, using type of transmission and whether the vehicle has air conditioning as the categorization variables.

If for a given vehicle it takes 20 hp to overcome aerodynamic drag while being driven at 55 mph, estimate the horsepower required at 65 mph.

Draw a schematic picture of a MSN being used as a molecular engineering design selective drug delivery vehicle. Label all key components of the design.

Eliminate repetition by replacing the boldfaced word or words with a synonym from your lesson words.

The speeding vehicle was clocked at a speed of 90 miles an hour
