A researcher decides to take a random sample of the population and determine the ALT levels of the population, which fall on a c

Answer:

False

Step-by-step explanation:

The given statement is false. The histograms or bar charts are used when one is given discrete data for a certain value or the interval of a certain range but for the continuous data plotting, we need continuous frequency curves line graphs. Since the ALT levels fall on a continuum, representing them on a bar chart will not make any sense. they should be plotted on some continuous curve distribution lines like smoot line graphs (curves).

What is the domain and derivative of f(x)=ln(2xsqrt(2+x))?
harkovskaia [24]
Domain is the numbers yo can use
we has a sqrt and a ln
we cant have any neagtive ln's or sqrts
x cannot be negative
it cannot be 0 either
domain is all numbers bigger than 0


deritivive
apply chain rule
dy/dx(f(g(x))=f'(g(x))g'(x)
and also
dy/dx (lnx)=1/x
and
dy/dx(f(x)g(x))=f'(x)g(x)+g'(x)f(x)
and from experience
dy/dx(sqrtx)=1/(2√x)


so

dy/dx(ln(2xsqrt(2+x)))=
(1/(2xsqrt(2+x))(2)(sqrt(2+x)+(x/(2sqrt(2+x))=
(3x+4)/(2x(x+2))



domain is all real numbers greater than 0
derivitive is \frac{3x+4}{2x(x+2)}
