Answer:
Mean= 13.38
Median= 15
Step-by-step explanation:
The mean can be calculated by getting the sun of the 8 scores and then dividing it by the number of students
Mean= 7 + 18 + 18 + 15 + 17 + 10 + 15 + 7/8
= 107/8
= 13.38
The median can be calculated by first rearranging the numbers from the lowest to the highest and then calculating the average of the two middle numbers
7 , 7, 10, 15, 15, 17, 18, 18
Median = 15+15/2
= 30/2
= 15
Hence the mean is 13.38 and the median is 15
Answer:
Step-by-step explanation:
<em>Hey there!</em>
Well angles like 142 and 2x + 22 equal each other because they are across from each other.
So we can set up the following,
142 = 3x + 22
Single out x
-22 to both sides
120 = 3x
Divide both sides by 3
x = 40
