Answer:

Step-by-step explanation:
In any square with side length
, the diagonal of the square is equal to
. Since the side length of this square is
, the diagonal is equal to
.
Alternatively, you can form two 45-45-90 triangles with the diagonal of the square. The diagonal acts as the hypotenuse for the both these triangles, and the legs of both triangles are equal to the side length of the square. To find the length of the diagonal, use the Pythagorean Theorem, which states
, where
is the hypotenuse of the triangle, and
and
are the two legs of the triangle.
In this question, both legs are equal to
, and we're solving for the diagonal, which is the hypotenuse in this case:

15.5
to find the volume of an object, you must multiply the 3d figure's dimensions which is depth, width, length. since the length, depth, and volume are found you must find the width using the expression of [L*D]/V=W
Answer:
The margin of error increases as the level of confidence increases because the larger the expected proportion of intervals that will contain the parameter, the larger the margin error.
Step-by-step explanation:
Margin of Error is a statistical measure of random sampling error insurvey results.
Level of confidence reflects percentage range around sample mean, that can be expected to contain population actual parameter.
High level of confidence means larger range band of confidence interval, supposed to contain the population parameter. This further implies high expected variation between sample statistic & actual parameter i.e Margin Error increases.
