Smartphones are advanced mobile phones with Internet, photo, music, and video capability. The survey results showing smartphone ownership by age are contained below. Use a spreadsheet to answer the following questions. Age Category Smartphone(%) Other cell phone (%) No cell phone(%)
18-24 49 46 5
25-34 58 35 7
35-44 44 45 11
45-54 28 58 14
55-64 22 59 19
65+ 11 45 44

Required:
a. Construct a stacked bar chart to display the above survey data on type of mobile phone ownership. Use age category as the variable on the horizontal axis.
b. Comment on the relationship between age and smartphone ownership.
c. How would you expect the results of this survey to be different if conducted in 2021?

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
