Answer:
a) An experiment is conducted based on random observations not on certain selected observations.
b) age, blood type etc
Step-by-step explanation:
a) We call the National Halothane Study an observational study rather than an experiment, because the anesthetics were not randomly chosen. They were prescribed by the doctors.
An experiment is conducted based on random observations not on certain selected observations.
b) There are factors such as age, sex, intensity , limit, tolerance and reactivity of the patient with the particular anesthetics chosen. If these are not carefully studied the results may not be as rewarding as desired.
If an anesthetics is chosen wihtou knowing the age or blood type for tolerance it may result in dangerous situations.
Some patients are highly tolerant with certain medications but others may die.
Answer:
Surface area of box = 94cm²
Step-by-step explanation:
Given that:
Width of box = 3 cm
Length of box = 5 cm
Height of box = 4 cm
Surface Area = 2lw + 2lh + 2hw
Surface area = 2( lw + lh + hw )
Surface area = 2(5*3 + 5*4 + 4*3) = 2(15+20+12)
Surface area = 2(47) = 94 cm²
Hence,
Surface area of box = 94cm²
Answer:
Part a) The scale of the new blueprint is 
Part b) The width of the living room in the new blueprint is 
Step-by-step explanation:
we know that
The scale of the original blueprint is
and
the width of the living room on the original blueprint is 6 inches
so
<em>Find the actual width of the living room, using proportion</em>
<em>Find the actual length of the living room, using proportion</em>
<em>Find the scale of the new blueprint</em>, divide the length of the living room on the new blueprint by the actual length of the living room
simplify
<em>Find the width of the living room in the new blueprint, using proportion</em>
r = 1/15
a branliest from the answer will be appreciated
