Answer:
7.3 in
Step-by-step explanation:
Area of triangle = (1/2) *b*h
27 = (1/2) * x^2
54 = x^2
square root (54) = x
x=> 7.3484....
Rounding off to 1 decimal place, you get 7.3 in.
2,320,502 <=== Two million, three-hundred and twenty thousand five hundred and two
The conclusion is valid
it is a systematic random sample
and the second one is a line graph (I think)
i just took the quiz and its 32 :)
