Nevaeh rolled a die 50 times and 9 of the 50 rolls came up as a six. She wanted to see how likely a result of 9 sixes in 50 rolls would be with a fair die, so Nevaeh used a
computer simulation to see the proportion of sixes in 50 rolls, repeated 200 times.
Create a 95% confidence interval based on the data from the simulation, to the
nearest hundredth, and state whether the observed proportion is within the margin
of error of the simulation results.

Acable company wants to provide cell phone service for residents on an island. the function for the cost of laying the cable from the island to the mainland is c(x)= 6.500 square root x2+4, where x represents the length of the cable in feet. what are the domain and range of the function? a) domain: all real numbers range: all real numbers greater than or equal to 17,000 b) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 17,000 c) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 13,000 d) domain: all real numbers greater than or equal to 13,000 range: all real numbers greater than or equal to 0
