The average of scores is 160.5
Step-by-step explanation:
Mean is the sum of all values divided by the number of values.
Given scores are:
138,151,198,147,156, and 173
The formula for average score is given by:
Putting values
The average of scores is 160.5

Quick answer: 68oF <<<<
A quick way to figure this out is to double the C temperature and add 30, just so you get an estimate.
F ~ 2*20 + 30 ~ 70oF
Now let's use the actual formula
F = 9/5 * C + 32
F = 9/5 * 20 + 32
F = 180/5 + 32
F = 36 + 32
F = 68o
68oC <<<<< answer.
△DEF is rotated about point N to △D′E′F′.
A rotation is a transformation that turns a figure about a fixed point called the center of rotation. In your case the center of rotation is point N. A rotation is an isometric transformation: the original figure and the image are congruent. Main properties of rotation:
1) A rotation preserves lengths of segments.
2) A rotation preserves degrees of angles.
3) A rotation maps a line to a line, a ray to a ray, a segment to a segment, and an angle to an angle.
Therefore, option C is true (because the original figure and the image are congruent) and option D is false (because the original figure and the image must be congruent).
All corresponding points on the image and pre-image are equidistant to point N. This option is true (because rotation preserves lengths of segments), thus, DN≅D'N'.
