Answer:
step 1
Step-by-step explanation:
step 1 he made the mistake
should have been:
h - 2 = 20
The answer to this question would be
5= rotating 90° clockwise
6= mirrored diagonally (\)
In this case, the picture in number 5 is moved 1 quadrant to the clockwise direction. In this problem, it is either the picture rotated 90° clockwise or mirrored to the Y lines. If it mirrored, the effect would be X point become minus. But seeing the point B and C, the effect is
1. X and Y switched
2. X become minus
This effect is gained when you rotating 90° clockwise
In number 6, the picture moved 2 quadrants. It will be either rotated 180° or mirrored diagonally. The effect on the image is:
1. X and Y switched
2. Both X and Y become minus
This effect is gained if the shape was mirrored.

Answer:
57.926%
Step-by-step explanation:
Calculation for the probability that it is less than
16.4 inches long
Using this formula
z = (X - μ) / σ
Where,
X represent Date=16.4
μ represent Mean=16.2
σ represent Standard deviation=0.9 inches
Let plug in the formula
z = (16.4 - 16.2) /0.9 inches
z=0.2/0.9 inches
z = 0.2
Using Z-score table to find the area of 0.2
z=0.57926*100
z=57.926%
Therefore the probability that it is less than
16.4 inches long is 57.926%
