1. A polar bear walk 2 miles North, then 4 mi East, then 4 mi West, then 3 mi South. The bear completes his trip in 4 hours. a) Sketch the motion of the bear. Clearly label positions (number and units) and directions throughout the bear’s trip. Also, label displacement vectors with magnitudes during the bear’s trip. b) What is the bear’s total distance traveled? c) What is the bear’s total displacement? (Include magnitude and direction.) d) Draw the displacement vector for the entire trip below. Label magnitude and show direction. e) What is the bear’s average speed during the trip? f) What is the bear’s average velocity during the trip? (Include magnitude and direction.)

If the measure of xyz is 81 what is the measure of yz

It appears that people who are mildly obese are less active than leaner people. one study looked at the average number of minutes per day that people spend standing or walking. among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately normally distributed with mean 376 minutes and standard deviation 64 minutes. the mean number of minutes of daily activity for lean people is approximately normally distributed with mean 528 minutes and standard deviation 107 minutes. a researcher records the minutes of activity for an srs of 7 mildly obese people and an srs of 7 lean people. use z-scores rounded to two decimal places to answer the following: what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes? what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes?

Suppose that the function f is defined. , for all real numbers, as follows. _ \ 1/4x² -4 if x≠ -2 f(x)=< /_-1 if x=-2 find f(-5), f(-2), and f(4)
