To compare the average amount of time that canadians and americans spend commuting, a researcher collects a sample of canadians and americans. The canadians spend an average of hours a week commuting, with a standard deviation hours. The mean and standard deviation for the sample of americans is hours and hours, respectively. The standard error of the difference of sample means is:.
The standard error of the difference of sample means is 0.444
From the complete question, we have the following parameters
Canadians
Sample size = 50Mean = 4.6Standard deviation = 2.9Americans
Sample size = 60Mean = 5.2Standard deviation = 1.3The standard error of a sample is the quotient of the standard deviation and the square root of the sample size.
This is represented as:
[tex]SE = \frac{\sigma}{\sqrt n}[/tex]
The standard error of the Canadian sample is:
[tex]SE_1 = \frac{2.9}{\sqrt{50}}[/tex]
So, we have:
[tex]SE_1 = 0.41[/tex]
The standard error of the American sample is:
[tex]SE_2 = \frac{1.3}{\sqrt{60}}[/tex]
So, we have:
[tex]SE_2 = 0.17[/tex]
The standard error of the difference of sample means is then calculated as:
[tex]SE= \sqrt{SE_1^2 + SE_2^2}[/tex]
This gives
[tex]SE= \sqrt{0.41^2 + 0.17^2}[/tex]
[tex]SE= \sqrt{0.197}[/tex]
Take square roots
[tex]SE= 0.444[/tex]
Hence, the standard error of the difference of sample means is 0.444

The passage is missing and it is;
This thinning would materially change the sound of the drum, evidence that although it might continue to be used for its original purpose of music-making or calling people to arms, it would now do so with a different voice. A musical instrument had become a trophy, and the new carvings were in fact branding, a statement of the north’s political dominance over Central Africa and of allegiance to Islam.

Figure p12. 4 shows three uniform objects: a rod, a right triangle, and a square. Their masses and their coordinates in meters are given. Determine the center of gravity for the three-object system.
The center of gravity for the three-objects system is approximately located
at their center of mass.
The center of gravity of the three-object system is approximately (2.58, 4.75)Reasons:
The coordinates of the vertices of the objects and their masses are;
The rod:
Vertices, (2, 7), and (9, 7)
Mass, m₁ = 6.00 kg.

Mass, m₃ = 5.00 kg
Required;
The center of gravity for the three-object system.
Solution:
The center of gravity is given by the formula;
[tex]\displaystyle X_c =\mathbf{ \frac{X_{c1} \times m_1 +X_{c2} \times m_2 +X_{c3} \times m_3 }{m_1 + m_2 + m_3}}[/tex]
[tex]\displaystyle Y_c =\mathbf{ \frac{Y_{c1} \times m_1 +Y_{c2} \times m_2 +Y_{c3} \times m_3 }{m_1 + m_2 + m_3}}[/tex]
Where;
[tex]X_{c1}[/tex] = The x-coordinates of the center of the rod = 5.5
[tex]X_{c2}[/tex] = The x-coordinate of the centroid of the triangle [tex]\displaystyle = \frac{4 + 8 + 8}{3} = \frac{20}{3}[/tex]
[tex]X_{c3}[/tex] = The x-coordinate of the centroid of the square = (-5 - (-2)) ÷ 2 - 2 = -3.5
[tex]Y_{c1}[/tex] = The y-coordinate of the center of the rod = 7
[tex]\mathbf{ Y_{c2}}[/tex] = The y-coordinate of the centroid of the triangle [tex]\displaystyle = \frac{7}{3}[/tex]
[tex]Y_{c3}[/tex] = The y-coordinate of the centroid of the square = 3.5
Therefore;
[tex]\displaystyle X_c = \mathbf{ \frac{5.5 \times 6 +\frac{20}{3} \times 3 +(-3.5) \times 5 }{6+ 3 + 5}} \approx 2.58[/tex]
[tex]\displaystyle Y_c = \mathbf{ \frac{7 \times 6 +\frac{7}{3} \times 3 +3.5 \times 5 }{6+ 3 + 5}} = 4.75[/tex]
