The conclusion is valid
it is a systematic random sample
and the second one is a line graph (I think)
Density = m/v
3.86kg=3860g
d= 3860/200
= 19.3g/cm^3
therefore it is gold.
Step-by-step explanation:
The area of triangle is
=21×height×base=21×3×4=3×2=6 cm2
Yes, they are independent event such that occurring the first event “choosing a sophomore” does not affect the probability of occurring the second event <span>“choosing someone who replied ‘Yes’”</span><span />
