If an octahedral die is weighted in such a way that 2 is twice as likely to come up as 1, 3 is three times as likely to come up as 1, and 4 is four times as likely to come up as 1, and so on up to 8, which is 8 times as likely to come up as 1, what is the probability distribution for the number that comes up

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
