Answer:
cos Θ = 
Step-by-step explanation:
Given the angle passes through (4, 5 ) then the right triangle with sides 4 and 5 has hypotenuse h given by
h² = 4² + 5² = 16 + 25 = 41 ( take the square root of both sides )
h = 
In relation to Θ, 4 is adjacent and 5 is opposite, thus
cos Θ = 
=
Answer:D
Step-by-step explanation:
This is combination.
If 4 books selected out of eight book in the shelf:
(4 combination 8)= 70
For hardback selection:
Then selection of 4 books out of the hardback, it means there is no paperbach will be:
(4 combination 6)= 15
So , if at least one paperback selected will be : 70-15
That is 55
Mean: Add all the numbers and divide by the amount of numbers.
20 + 0 + 7 + 10 + 11 + 0 + 25 + 15 + 1 = 89
89/9 = 9.889 (rounded)
Mean = 9.889 (rounded)
Median: Reorder from least to greatest, and the middle number is the median.
0, 0, 1, 7, 10, 11, 15, 20, 25
The middle number is 7
Median = 7
Mode: The number that shows up the most.
Mode = 0, which shows up one time more than all the other numbers
Range: Subtract the greatest number with least number
25 - 0 = 25
Range = 25
