A jar has 9 pennies, 3 nickles, 8 dimes and 5 quarters. A coin is chosen at random, NOT REPLACED (not replaced is key), then another is chosen. Find the probability that a quarter was chosen followed by a penny. Write your answer as a fraction.​

The number of fish in a lake can be modeled by the exponential regression equation y=14.08 x 2.08^x where x represents the year

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.

Which equation can be simplified to find the inverse of y = 2x2^2
