The length of a petal on a certain flower varies from 2.89 cm to 7.29 cm and has a probability density function defined by f(x) = 1/2 squareroot x. find the probabilities that the length of a randomly selected petal will be as follows. a. greater than or equal to 4.7 cm b. less than or equal to 3.8 cm c. between 3.8 cm and 4.7 cm a. the probability that the length of a randomly selected petal is greater than or equal to 4.7 cm is. (round to four decimal places as needed.)

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

If the value of x increases by 5, how does the value of m(x + 3) change? a) it increases by 5m. b) it increases by 8m. c) it decreases by 5m. d) it decreases by 8m.
