im sure it would be 2:4. if it was to be simplified it would be 1:2
Let
cos x=7/18
x=arc cos (7/18)-----> using a calculator-------> x=67.11°-----> x=1.17 radians
the answer is
x=67.11° or x=1.17 radians
Answer:
The number of enrollments increased by 5%.
Step-by-step explanation:
Given that:
Number of students at the beginning of the year = 480
Number of students at the end of the year = 504
Change = 504 - 480 = 24
This indicates increase.
Percent of change = 
Percent of change = 
Percent of change = 5%
Hence,
The number of enrollments increased by 5%.
The mode is what number occurs most often. So in this set, the number that occurs most often is 5.
Mode = 5
The mean is the average of all the numbers in the set. To find the average of numbers, you add them all up then divide by how many numbers there are in the set. 5 + 6 + 8 + 3 + 5 + 7 + 4 + 11 + 5 + 7 = 61. 61 divided by 10 = 6.1 The answer is 6.1
Mean = 6.1
Good luck, my guy!
