9. If the amount of K-12 education expenses in Indiana were proportional to those in Ohio, what would have been the
expected value of K-12 expenditures in Indiana? (give the answer in billions rounded to the nearest hundredth)
10. Use the value of K-12 education expenditures in Michigan as a proportion of the population in Michigan to estimate
what the value of K-12 education expenses would be in Illinois.
a) Find the expected value of K-12 expenditures in Illinois if Illinois were proportional to Michigan. (give the answer
in billons rounded to the nearest hundredth)
b) How does this compare to the actual value for K-12 expenditures in Illinois ? (lower, higher, same?)
11. The U. S. population was 309 million in 2010. If the U. S. had had the same firearm death rate as Australia in 2010,
how many firearm deaths would the U. S. have expected to have that year? Australia's population was 22.3 million
people in 2010. Australia had 236 firearm deaths in 2010. (round to the nearest person)

Find the missing factor in exponential form 48^2=3^2 • ?

Airplane speeds are measured in three different ways: (1) indicated speed, (2) true speed, and (3) ground speed. the indicated airspeed is the airspeed given by an instrument called an airspeed indicator. a plane’s indicated airspeed is different from its true airspeed because the indicator is affected by temperature changes and different altitudes of air pressure. the true airspeed is the speed of the airplane relative to the wind. ground speed is the speed of the airplane relative to the ground. for example, a plane flying at a true airspeed of 150 knots into a headwind of 25 knots will have a ground speed of 125 knots. the problems below refer to static and dynamic pressure. static pressure is used when a body is in motion or at rest at a constant speed and direction. dynamic pressure is used when a body in motion changes speed or direction or both. a gauge compares these pressures, giving pilots an indicated airspeed. in problem #s 1 and 2, use the following information. the indicated airspeed s (in knots) of an airplane is given by an airspeed indicator that measures the difference p (in inches of mercury) between the static and dynamic pressures. the relationship between s and p can be modeled by s=136.4p√+4.5. 1. find the differential pressure when the indicated airspeed is 157 knots. 2. find the change in the differential pressure of an airplane that was traveling at 218 knots and slowed down to195 knots. in problem #s 3 and 4, use the following information. the true airspeed t (in knots) of an airplane can be modeled by t=(1+a50,000) ⋅ s, where a is the altitude (in feet) and s is the indicated airspeed (in knots). 3. write the equation for true airspeed t in terms of altitude and differential pressure p. 4. a plane is flying with a true airspeed of 280 knots at an altitude of 20,000 feet. estimate the differential pressure. explain why you think your estimate is correct.

Kendra had twice as much money as kareem. kendra later spent $8 and kareem earned $6. by then,the two had the same amount of money. how much money did each have originally?
