I think it should be (13,12) but I am not sure but it’s rise over run so that should be correct
It is 99.5% because 99.5% is in the middle of 99% and 100%
hope I helped!!!
Answer:
85.7
Step-by-step explanation:
Given that two sections of a class took the same quiz. Section A had 15 students who had a mean score of 80, and Section B had 20 students who had a mean score of 90.
Section A total score = 15*80=1200
Section B total score 20*90 = 1800
Overall total score=3000
Overall total students = 15+20 =35
Hence overall mean = 
rounding off to one decimal place
overall mean = 85.7
Y=-6(10)+15
y=-60+15
y=-45
y=-120+15
y=-105
range equals -105 to 45
