The nests built by the mallee fowl of australia can have masses as large as 3.4 × 105 kg. suppose a nest with this mass is being lifted by a crane. the boom of the crane makes an angle of 45.0° with the ground. if the axis of rotation is the lower end of the boom, the torque produced by the nest has a magnitude of 3.75 × 107 n•m. treat the boom’s mass as negligible, and calculate the length of the boom.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
