A researcher uses a within-group design to test whether a cognitive training app improves working memory performance. Participants complete the same working memory task at three time points: once before using the app, once after two days of training, and once after one week of training. The researcher finds steady improvement across all three testing sessions. Which interpretation best reflects a limitation of this design?

A dental office requires radiographers to follow written protocols including proper patient identification, reviewing medical history, verifying exposure settings, and documenting radiographic findings. These protocols are examples of:

Knowledge & Application      The position, in metres, of an object moving along a straight line from left to right, is given by the function  . The object’s motion is recorded starting at t = 0, where t is measured in seconds. a) Determine the object’s position at t = 3 (1 mark) b) When is the object moving in a positive direction? (6 marks)

A clinician reviews a CBCT scan and observes streaking artifacts and areas of high attenuation that obscure adjacent anatomy. The artifact originates from a highly radiopaque restoration.  Which restoration is most likely responsible for this artifact? 

Cumulative 121 g Ni is reacted with 47 g HF to produce NiF2 via the reaction

Application    You would like to construct a box that has a base length that is twice the width of the base.  You know that the material to build the top and bottom costs $9/m2 and it costs $6/m2 for the sides.  You would like the box to have a total volume of 70 m3. Determine the length, width, and height of the box (in metres) that will minimize the cost of production.  What is the minimum cost?
