Cual es el resultado de la siguiente operación. \( 9 / 5+7 / 8 \) \( 1 / 10 \)

Find the distance between the pair of points \( (2,2) \) and \( (9,9) \). If necessary, express the answer in simpl The distance between the given points is \( 7 \sqrt{2} \) units. (Simplify your answer. Type an exact answer, using radicals as needed.) Express the distance rounded to two decimal places if the exact simplified answer contains radicals. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The distance between the given points is approximately units. (Type an integer or decimal rounded to two decimal places as needed.) B. The exact simplified form does not contain radicals.

c) \( \sqrt[3]{x}=-4 \)

The weights, in pounds, of packages on a delivery truck are shown in the stem-and-leaf plot. Find the mean, the median, and the mode of the data, if possible. If any measure cannot be found or does not represent the center of the data, explain why. Find the mean. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The mean is (Round to one decimal place as needed.) B. The mean cannot be calculated because there is an even number of data entries. C. The mean cannot be calculated because the data are at the nominal level of measurement. D. The mean cannot be calculated because the sample size is too small. Does the mean represent the center of the data? Choose the correct answer below. A. The mean represents the center of the data set. B. The mean does not represent the center because it is the least data entry. Find the median. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. C. The mean does not represent the center because it is not a data entry. D. The mean does not represent the center because it is the greatest data entry. F. The data set does not have a mean.
