Three coins are tossed. Let the event H = all Heads and the event K = at least one Heads. (match like 1-a, etc) 1. 7/8
2. 1/7
3. 1/8
a. The probability that the outcome is all heads if at least one coin shows a heads
b. P(K) =
c. P(H∩K) =

Imogene invested $8,000 in a bank account that pays 8 percent simple interest at the end of each year. her friend invested the same amount in stocks where the growth of the investment is represented as 2,000 times the square root of 2 less than the time lapsed in years. if y1 and y2 represent the amount earned in dollars and t is the time lapsed in years, which system of equations correctly represents the situation?

Could somebody me with this radical simplification?

Match each whole number with a rational, exponential expression 3 square root 27^2find the domain and range of the exponential function h(x)=125^x. explain your findings. as x decreases does h increase or decrease? explain. as x increases does h increase or decrease? explain.
