She asked her friends, which does not represent a random sample.
She tried to show cause and effect without doing an experiment (which includes simple random sample, control group, treatment, etc).
So the answer is she did not use a random sample, and tried to show cause and effect with an observational study.
(x+2)(x+1) = x^2 + x + 2x + 2
simplify it
x^2 + 3x + 2

Answer:
The range of the graph is all real numbers greater than or equal to 0.
Step-by-step explanation:
we have

using a graphing tool
The graph in the attached figure
step 1
Find the domain
we know that the radicand of the function must be greater than or equal to zero
so
The domain is the interval ------> [0,∞)

All real numbers greater than or equal to zero
step 2
Find the range
The range is the interval -----> [0,∞)

All real numbers greater than or equal to zero
Answer:
419 ft
Step-by-step explanation:
1063 ft is about 324002.4 mm
324002.4/477 to get the scale ratio. Which is 679.25:1
I am halfway through the problem and notice I should have converted mm to ft and not the other way around. It gives the same answer it just takes an extra step.
188*679.25=127699mm for one side.
Convert that back to ft and you get 418.959 which would just be 419 ft
