Answer:
Interquartile Range = 34
Range = 55
Step-by-step explanation:
Max - Min = Range
75 - 20 = 55
Quartile 3 - Quartile 1 = IQR
68 - 34 = 34
Answer:
Mean = 24
Variance = 107.78
Standard deviation = 10.38
Hope this helps! :)
We know, cos A + cos B = 2cos(C+D)/2 × cos(C - D)/2
So,
cos 130 + cos 110 + cos 10
cos 130 + 2cos (110+10)/2 × cos( 110-10)/2
cos 130 + 2cos 60 × cos 50
cos ( 180 - 50 ) + 2cos60 cos 50
We know, cos ( 180 - A ) = -cos A
2cos 60 cos 50 - cos 50
Also, cos 60 = 0.5
2×0.5 cos 50 - cos50
cos 50 - cos 50
0 = RHS.
Hence proved
Answer:
7/8 is larger than 5/6
Step-by-step explanation:
If you divide the numerator by the denominator of each given fraction:
7/8 = 0.875
5/6 = 0.833
We can easily see that 0.875 > 0.833.
Therefore, 7/8 is larger than 5/6.
The answer is 253/3 ...........
