Answer #1

28.5cm2     = 28.5(10-5km)2                                         1cm = 10-5 km

                 = 28.5*10-10Km2

                 = 2.85*10-9 km2   >>>>> answer

Scientists measured the annual forest loss (in square kilometers) in Indonesia from 2000–2012. They found the regression line forest loss=7500+(1021×years since 2000) for predicting forest loss in square kilometers from years since 2000. 1. What is the slope of this line? Round to the whole number. slope= 2. Select the statement that describes in words what the numerical value of the slope tells you. For each year since 2000, forest loss averages about 7500/12km^2 For each year since 2000, forest...

he number of lightening strikes on a square kilometer of open ground in a year has mean 5 and standard deviation 2.1. The National Lightening Detection Network used automatic sensors to watch for lightening in a sample of 16 randomly chosen square kilometers. What is the probability that the average number of lightening strikes per kilometer per year for 16 randomly chosen square kilometers is 4.8 or more?

To find the square root of x, make a guess g. If g**2 is close enough to x, then report g as the square root. Otherwise, make a new guess which is the average of g and x/g. Check the new guess and keep repeating until the square of the guess is close enough to x. Suppose x is 99 and the first guess is 5. Using this algorithm, how many guesses will it take until the guess squared is...
