Answer:
Step-by-step explanation:
This could be an observational study because an experiment was not carried out by the research to further verify this hypothesis. Individuals are observed and data is collected from such observation. No effort is made by the researcher to affect the outcome of such results.
This study alone is not enough to conclude about a cause and effect relationship between steroids and the increase in home runs as thus study is not randomized and cant control other factors or links bringing about this result.
I believe 8.30%..........

the va's are where x is undefined, or where the denomenator is zero
first simplify if applicable
cannot simplify
set denom to zero
2x-5=0
2x=5
x=2.5
the vertical assemtote is vertical so it is x=2.5 or 5/2
the VA is x=5/2
Answer:
Step-by-step explanation:
if it is linear then it will be a straight line(gradient is the same)
if quadratic then curve(gradeint isnt the same)
y=mx+c
m=[y(2)-y(1)]/[x(2)-x(1)]
you can choose any 2 points from the table
m=2-0.4/0-1
m=-1.6
repeat but 2 different coordinates
m=0.4-0.08/-1--2==>-2.24
m=-2.24
different coordinate therefore quadratic
cant be exponential, because nothing is being raised to some power
