Answer:
The first number (or x value) of an ordered pair.
Step-by-step explanation:
Abscissa is the first number (or x value) of an ordered pair.
A coordinate plane is a way of locating points in a plane that consists of a horizontal and a vertical number line intersecting at the zeros.
Coordinates are an ordered pair, (x, y), that describes the location of a point in the coordinate plane.
Ordinate is the second number (or y value) of an ordered pair.
Origin is the point of intersection, (0, 0), of the axes in the coordinate plane.
A quadrant is a region in the coordinate plane.
X axis is the horizontal axis in the coordinate plane.
Y axis is the vertical axis in the coordinate plane.
Im guessing either 2/3*570 or 1/3*5700
-x = -1. Anything “X” equals to the number One. So do Y = -1 + 1.
Answer:
538 books should be tested.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so 
Now, find the margin of error M as such

In which
is the standard deviation of the population and n is the size of the sample.
How many books should be tested to estimate the average force required to break the binding to within 0.08 lb with 99% confidence?
n books should be tested.
n is found when 
We have that 






Rounding up
538 books should be tested.
