Answer:

Hi it's down below! Hope it helps

Step-by-step explanation:

1) The angles are Supplementary

This is because both angles form 180°. The angle below angle "7x+9" is the same as 5x+3.  The angle above angle"5x+3" is the same as 7x+9.

2) They are both supplementary

They form 180°

3)180° = 12x+12°

4) Solving that:

180° - 12° = 12x

168° = 12x

x = 168°/12

x = 14°

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!

Answer: Company A mean = 14.65 million Company B mean = 14.32 million.

Step-by-step explanation:

The mean, or average, is calculated by adding up the scores and dividing the total by the number of scores.

Company A mean = 12.8 + 15.0 + 31.0 + 13.0 + 14.0 + 12.9 + 12.7 + 11.9 + 11.7 + 11.5 = 146.5/ 10 = 14.65 million

Company B mean = 13.8 + 14.0 + 14.5 + 14.3 + 14.6 + 14.5 + 14.2 + 14.7 + 14.4 + 14.2 = 143.2/ 10 = 14.32 million

The median is the middle score of a distribution. To calculate the median

Arrange your numbers in numerical order.

Count how many numbers you have.

If you have an odd number, divide by 2 and round up to get the position of the median number.

If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

Currently i'm providing you the mean solution im working on the median I haven't learned it.
