To find area, you use L + W + H.
Add up all the numbers given and you’ll be able to find surface area.

4 + 7 + 10 + 11 + 10 = 42 m^2

The impact on sampling of increasing the sample size is: There is no specific relationship between sample size and sampling erro
m_a_m_a [10]

Using margin of error, it is found that increasing the sample size results in a smaller sampling error.

The equation for the <em>margin of error</em> is given by:

M = c\frac{s}{\sqrt{n}}

In which:

  • c is the critical value according to the distribution used.
  • s is the standard deviation, either of the sample or of the population.
  • n is the sample size.

From the equation, it can be noted that the margin of error is inversely proportional to the square root of the sample size, hence, increasing the sample size results in a smaller sampling error.

The perimeter of the rectangle is 76 units. Find the length of side pq
larisa [96]

Answer:   PQ=16\ units

Step-by-step explanation:

The missing figure is attached.

The perimeter of a rectangle is:

P=2l+2w

Where "l" is the lenght and "w" is the width.

You can identify in the figure that:

w=SR=PQ=2z+2\\\\l=QR=PS=3z+1

Then, knowing the perimeter of the rectangle, you can make the subsitution into the formula:

 76=2(3z+1)+2(2z+2)

Now you must simplify and solve for "z"

76=6z+2+4z+4\\\\76-6=10z\\\\70=10z\\\\\frac{70}{10}=z\\\\z=7

Finally, substituting the value of "z" into  PQ=2z+2, you get:

 PQ=2(7)+2=16\ units
