The results of the experiment are shown in the frequency side
a) 14
b) 3600 Best guess 300*12
Answer: its b ;p
Step-by-step explanation:
34.5=4h+7c
(34.5-7c)/4=h
Put h= (34.5-7c)/4 into another equation
30.5=8h+3c
30.5=2(34.5-7c)+3c
30.5=69-14c+3c
11c=38.5
c=38.5/11
Put c=38.5/11 into one of the equations
to calculate the h.
X=10 and y=5 so it's the first option
