First you multiply 12 by 27
The answer is your answer (324)
Answer:
The expected frequency is 90
Step-by-step explanation:
If the given probabilities are taken as observed
pXL=0.10, 450*0.1= 45
pL=0.20, 450*0.2= 90
pM=0.40, 450*0.4= 180
pS=0.20, 450*0.2= 90
pXS=0.10 450*0.1= 45
We can assign the expected frequencies to be 450/5= 90 each
The chi square goodness fit test can be calculated as
Observed Expected (o-e) (o-e)² (o-e)² /e
45 90 -45 2025 22.5
90 90 0 0 0
180 90 90 8100 90
90 90 0 0 0
<u> 45 90 -45 2025 22.5 </u>
<u>∑ 135 </u>
<u />
χ²= 135
The χ² value at 0.05 is 9.49
The result is significant.
Answer:
7.065
Step-by-step explanation:
Area of a circle: Pi*r^2
r= 1.5
pi* 1.5^2
2.25pi
Around 7.065
Given:
The figure of a trapezoid.
The figure is translated down 5 units and then rotated 180 degrees clockwise.
To find:
The coordinates of the image of point W after these transformation.
Solution:
From the given figure it is clear that the coordinates of point W are (-6,3).
The figure is translated down 5 units. So,
After that the figure is rotated 180 degrees clockwise.
Therefore, the coordinates of point W after the given transformations are (6,2).
