Listed below are pulse rates​ (beats per​ minute) from samples of adult males and females. Does there appear to be a difference find the coefficient and variation for each of the two samples then compare the variation male: 87 68 61. 68 69 53 62 54 84 72 61 60 100 58 66 females: 65 81 82 70 74 86 87 84 88 89 94 71 86 80 78 The cofficient of variation for the males pulse rate ?

Astuntman jumping off a 20-m-high building is modeled by the equation h=20-5t^2, where t is the same in seconds. a high-speed camera is ready to film him between 15m and 10m above the ground. for which interval of time should the camera film him?

Someone answer asap for ! the boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a. e = 2b - 212 b. b = 2e - 212 c. e = -2b + 212 d. b = -2e + 212
