The wind-chill index is modeled by the function W − 13.12 1 0.6215T 2 11.37v 0.16 1 0.3965Tv 0.16 where T is the temperature sin 8Cd and v is the wind speed sin kmyhd. The wind speed is measured as 26 kmyh, with a possible error of 62 kmyh, and the temperature is measured as 2118C, with a possible error of 618C. Use differentials to estimate the maximum error in the calculated value of W due to the measurement errors in T and v.

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.
