Answer: The Z-value is a test statistic for Z-tests that measures the difference between an observed statistic and its hypothesized population parameter in units of the standard deviation. ... A mold with a depth of 12 cm has a Z-value of 2, because its depth is two standard deviations greater than the mean
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
We have that
<span>Consider the graph of the line y = x – 4 and the point (−4, 2).
part 1)</span><span>The slope of a line parallel to the given line is
the slope m of the given line
y=x-4-----> y=(1)*x-4
is m=1
the answer Part 1) ism=1Part 2) </span><span>A point on the line parallel to the given line, passing through (−4, 2)
the slope m=1
y-y1=m*(x-x1)------> y-2=(1)*(x+4)-----> y=x+4+2------> y=x+6
the answer Part 2) isy=x+6part 3) </span><span>The slope of a line perpendicular to the given line is .
we know that
when two lines are </span>perpendicular
m1*m2=-1
m1=1
m2=-1
the answer part 3) ism=-1Part 4) <span>A point on the line perpendicular to the given line, passing through (−4, 2), is
</span>the slope m=-1
y-y1=m*(x-x1)------> y-2=(-1)*(x+4)-----> y=-x-4+2------> y=-x-2
<span>
the answer Part 4) isy=-x-2see the attached figure</span>
