I need help with Q6. I don’t know how to find theta

  (a) 45°

  (b) 60°

Step-by-step explanation:

1. Read your scientific or graphing calculator's manual.

2. Put the calculator into "degrees" mode.

3. (a) Use the inverse sine function:

  sin⁻¹(.707107) = 45.000°

  (b) Use the inverse cosine function:

  cos⁻¹(0.5) = 60.000°

___

Often, these functions are available as "2nd" functions on the same keys as the sin or cos functions.

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
