Answer:
85.6%
Step-by-step explanation:
To get two overall performance of Harry, we need to calculate his average score.
Average is also known mean score.
Mean = sum of the score/Total math subjects offered
Mean = 95+ 90+85+40+100+100+85+90/8
Mean = 685/8
Mean = 85.6
Hence her overall performance is 85.6%
The measure of central tendency used is 85.6%
4
2-(-2)=2+2=4
x=16
(4x+2)+(x+8)=90
5x+10=90
5x=80
this is not a answer but look up dezmos and it will graph it for you
Is there an answer key?
