James is trying to shoot three balls of different sizes consecutively through a hoop with a diameter of 18 inches. The balls have volumes of $850 \pi, 900 \pi$, and $950 \pi$ cubic inches. How many of the balls will fit through the hoop?

What two factors are most responsible for limiting life in a particular area?

A. sunlight and temperature

B. precipitation and temperature

C. precipitation and sunlight

D. soil conditions and precipitation

Bicycling World, a magazine devoted to cycling, reviews hundreds of bicycles throughout the year. Its Road-Race category contains reviews of bicycles used by riders primarily interested in racing. One of the most important factors in selecting a bicycle for racing is its weight. The following data show the weight (pounds) and price ($) for ten racing bicycles reviewed by the magazine:$

$$\begin{array}{lcc} \text { Model } & \text { Weight (lbs) } & \text{ Price (\$) } \\ \text { Fierro 7B } & 17.9 & 2200 \\ \text { HX 5000 } & 16.2 & 6350 \\ \text { Durbin Ultralight } & 15.0 & 8470 \\ \text { Schmidt } & 16.0 & 6300 \\ \text { WSilton Advanced } & 17.3 & 4100 \\ \text { bicyclette vélo } & 13.2 & 8700 \\ \text { Supremo Team } & 16.3 & 6100 \\ \text { XTC Racer } & 17.2 & 2680 \\ \text { D'Onofrio Pro } & 17.7 & 3500 \\ \text { Americana \#6 } & 14.2 & 8100 \end{array}$$

$Test whether each of the regression parameters$\beta_0$and$\beta_1$is equal to zero at a$0.05$ level of significance. What are the correct interpretations of the estimated regression

In a cold environment, a person can lose heat by conduction and radiation at a rate of about $200 \mathrm{~W}$. Estimate how long it would take for the body temperature to drop from $36.6^{\circ} \mathrm{C}$ to $35.6^{\circ} \mathrm{C}$ if metabolism were nearly to stop. Assume a mass of $70 \mathrm{~kg}$. (See Table 19-1.)

Consider an air-standard jet engine cycle operating in a 280-K, 100-kPa environment. The compressor requires a shaft power input of 4000 kW. Air enters the turbine state 3 at 1600 K and 2 MPa, at the rate of 9 kg/s, and the isentropic efficiency of the turbine is 85%. Determine the pressure and temperature entering the nozzle.

Which directive marks the end of a conditional block of statements?

James McDonnell purchases $800$ pounds of potatoes at a cost of $\$0.18$ per pound. If he anticipates a spoilage rate of $20\%$ of the potatoes and wishes to make a profit of $140\%$ of the cost, for how much must he sell the potatoes per pound?

Prove the formula C(k-1,k-1)+C(k,k-1)+...+C(n+k-2,k-1)=C(k+n-1,k)

Perform the indicated operations. $(x-1)(x+2)(x-3)$

1. Write a C++ statement that declares secretList to be a vector object to store integers. (Do not specify the size of secretList.)

2. Write C++ statements to store the following values, in the order given, into secretList:

56, 28, 32, 96, 75

3. Write a for loop that outputs the contents of secretList. (Use the expression secretList.size() to determine the size of secretList.)

An aluminum rod $2.0 \mathrm{~cm}$ in diameter and $12 \mathrm{~cm}$ long protrudes from a wall that is maintained at $250^{\circ} \mathrm{C}$. The rod is exposed to an environment at $15^{\circ} \mathrm{C}$. The convection heat-transfer coefficient is $12 \mathrm{~W} / \mathrm{m}^2 \cdot{ }^{\circ} \mathrm{C}$. Calculate the heat lost by the rod.

A balloon having an initial temperature of $20^{\circ} \mathrm{C}$ is heated so that the volume doubles while the pressure is kept fixed. What is the new value of the temperature?

which of the following statements is true concerning feedback mechanisms?

The formula $C=\frac{5}{9}(F-32)$, where $F \geq-459.7$, represents the Celsius temperature $C$ as a function of the Fahrenheit temperature $F$.

Find the inverse function of $C$.
