Suppose you have to work 360 minutes at your job tomorrow. What number of minutes corresponds to 1% of the total number of minutes you have to work tomorrow? minutes To find the number in part (a), we can multiply 360 by what number? If you have worked 1% of the total 360 minutes, what percent of the 360 minutes do you have left to work? % If you have worked 1% of the total 360 minutes, how many minutes do you have left to work? minutes To find the answer in part (d), we can multiply 360 by what number?

An insured has $5,000 of medical coverage on a personal auto policy at the time of a covered accident. The insured and two passengers are injured. Medical treatment costs $7,000 for the insured, $4,000 for the first passenger, and $8,000 for the second passenger. How much will the policy pay under medical payments coverage?

Biologists have found that the number of chirps some crickets make per minute is related to temperature. The relationship is very close to being linear. When crickets chirp 124 times a minute, it is about 68°F. When they chirp 172 times a minute, it is about 80°F. (a) Find an equation for the line that models this situation; (b) How warm is it when the crickets are chirping 160 times a minute?

Suppose you take a 15 question True or False quiz and you guess on every problem. You only get 3 correct. (a) What is the probability of getting 3 or fewer correct guesses? Round your answer to 3 decimal places. (b) Would 3 be an unusually low number of correct guesses? Use the criteria that a number (x) is unusually low if P(x or fewer) ≤ 0.05. Yes, that is an unusually low number of correct guesses. No, that is not an unusually low number of correct guesses.

Which technique for gathering data (observational study or experiment) do you think was used in the following studies? Explain your answer. (a) The U.S. Census Bureau tracks population age. In 1900, the percentage of the population that was 19 years old or younger was 44.4%. In 1930, the percentage was 38.8%; in 1970, the percentage was 37.9%; and in 2000, the percentage in the age group was down to 28.5% (The First Measured Century, T. Caplow, L. Hicks, B. J. Wattenberg).

The probability that a customer's order is not shipped on time is 0.10. A particular customer places three orders, and the orders are placed far enough apart in time that they can be considered to be independent events. Round your answers to four decimal places (e.g. 98.7654). (a) What is the probability that all are shipped on time? Entry field with incorrect answer now contains modified data .001

One thousand tonnes (1000 t, one t equals 10 cubed kg) of sand contains about a trillion (10 super 12) grains of sand. How many tonnes of sand are needed to provide 1 mol of grains of sand? (b) Assuming the volume of a grain of sand is 1.0 mm3 and the land area of the continental United States is 3.6 multiplication 10 super six square miles, how deep would the sand pile over the United States be if this area were evenly covered with 1.0 mol of grains of sand?

Sometimes a change of variable can be used to convert a differential equation y′=f(t,y) into a separable equation. One common change of variable technique is as follows. Consider a differential equation of the form y′=f(αt+βy+γ), where α,β, and γ are constants. Use the change of variable z=αt+βy+γ to rewrite the differential equation as a separable equation of the form z′=g(z). Solve the initial value problem y′=(t+y)2−1, y(3)=4.

A piecewise function g(x) is represented by the graph. On a coordinate plane, a piecewise function has 3 lines. The first line has an open circle at (negative 2, negative 2) and it continues horizontally to (negative 5, negative 2). The second line has a closed circle at (negative 2, 0) and then continues up to an open circle at (1, 1.5). The third line has a closed circle at (1, 4) and continues down to (5, negative 4). Which functions represent a piece of the function? Select three options. g(x) = −2x, −2 < x < 0 g(x) = −2, x < −2 g(x) = x − 2, −2 < x < 1 g(x) = −2x + 6, x ≥ 1 g(x) = + 1, –2 ≤ x < 1
