Question from Intermediate Algebra 10th edition by Pearson (Ch 1.7 hw probolem 57) "IBM estimated that 2.5 exabytes of information was generated everyday in 2012 by the worldwide population of 7.1 billion people. Given that an average double spaced typed page is equivalent to 2 kilobytes of information, each person generated , on average, is equivalent of how many typed pages of information?" I know what im given, and know I have to write to answer in correct scientific notation. Ive read the chapter over and over but I still dont know what equation Im supposed to use to solve this, because the text book isnt really specific on what to do.

#6) You use 2,500 incandescent holiday lights to decorate your apartment in Huntington. When turned on, the combined power of those lights is 1200 Watts. The electricity cost around is 6.40 cents per kilo- Watt-hour. How much is the total cost of electricity for the lights if you operate the 2,500 incandescent holiday lights for 24 hours per days for 50 days? Report your answer with the proper number of sig figs and rounding. Show all conversions. Express answer to 3 sig figs. Report answer in dollars.

A certain city's power company charges their residents for electricity usage on a daily basis. There is a basic charge of 11.57 cents. For each day the first 10 kWh cost 4.81 cents per kWh and any additional kWhs are 9.69 per kWh. (A kWh, or kilowatt-hour, is a unit of energy.) (a) Complete the following table using the information provided above. kWhkWh 0 5 10 15 20 cost (dollars)cost (dollars)           kWhkWh 25 30 35 40 cost (dollars)cost (dollars)         (b) We can define a piecewise function f(x)f(x) where xx is the kWh used in a day and f(x)f(x) is the cost, in dollars. This function would have the form   f(x)={g(x)h(x)ififx∈Ax∈Bf(x)={g(x)ifx∈Ah(x)ifx∈B What functions g(x)g(x) and h(x)h(x) make up the piecewise function f(x)f(x)? g(x)=g(x)= for A = h(x)=h(x)= for B = Hint: A and B are intervals. If an interval uses ±∞±∞ write inf or -inf . (c) Using the above function, what is the cost of 26 kWh? dollars. (d) For 3 dollars, what is the maximum kWh usage for one…

Calculate the age standardized IHD mortality rate using the Standard population.  Show all calculations. (See attached image)   Shouldn't the answer be like this? : Age-specific rate, 0 to 19 years= 11 (number of deaths) ÷ 9043000 (total population) × 40,000=  0.0487 IHD deaths  Age-specific rate, 20 to 39 years = 606 (number of deaths) ÷ 12543000 (total population) × 28, 000= 1.35 IHD deaths  Age-specific rate, 40 to 59 years= 10,071 (number of deaths) ÷ 11060000 (total population) × 21,000= 19.1 IHD deaths Age-specific rate, 60 to 79 years = 44947 (number of deaths) ÷ 6568000 (total population) × 10,000 = 68.4 IHD deaths Age-specific rate, 80+ years = 28940 (number of deaths) ÷ 779000 (total population) × 1000  = 37.2 IHD deaths    MULTIPLYING EACH BY THE STANDARD POPULATION FOR EACH AGE GROUP, NOT MULTIPLYING BY 100,000?? And do we add all the numbers up to get 126 deaths per 100,000 people or do we leave the numbers for each age group as is?   Thank you.

Stuck need help! Problem is attached. please view attachment before answering.  Really struggling with this concept. Please explain so I can better understand ! Thank you so much

Español Weber's law, a concept taught in most Introduction to Psychology courses, states that the ratio of the intensity of a stimulus to the "just noticeable" increment in intensity is constant, that is, the ratio doesn't depend on the intensity of the stimulus. The ratio is called the "Weber fraction," so a concise statement of Weber's law is that "the Weber fraction is constant, regardless of the stimulus intensity." It turns out that Weber's law is not so much a law as it is a rule of thumb, since it is violated in many situations. For instance, for some auditory stimuli, the Weber fraction does depend systematically on the stimulus intensity. The following bivariate data are the experimental data obtained for one listener in an auditory intensity discrimination task. For each of the ten stimulus intensities x (in decibels), the Weber fraction y (in decibels) is shown. Figure 1 is a scatter plot of the data. Also given is the product of the stimulus intensity and the Weber fraction…
