Answer:
B. web-only financial institution is the correct answer.
Explanation:
The standard error of the difference of sample means is 0.444
From the complete question, we have the following parameters
<u>Canadians</u>
- Sample size = 50
- Mean = 4.6
- Standard deviation = 2.9
<u>Americans</u>
- Sample size = 60
- Mean = 5.2
- Standard deviation = 1.3
The standard error of a sample is the quotient of the standard deviation and the square root of the sample size.
This is represented as:
The standard error of the Canadian sample is:
So, we have:
The standard error of the American sample is:
So, we have:
The standard error of the difference of sample means is then calculated as:
This gives
Take square roots
Hence, the standard error of the difference of sample means is 0.444

Answer:
26
Explanation:
Ok, so every rectangle has a triangle in it. If you draw a diagonal line across it, you'll see it. As you can tell, this is a question asking to do that, and since you have to visualize a lot, it's best to sketch out problems like this.
1. The length and height stay the same for the triangle. The diagonal length doesn't correlate to rectangle height or length.
2. So, we just have the missing side of a triangle since we already know length and height. The diagonal is the hypotenuse.
3. Use the Pythagorean Theorem: . A and B are any leg you choose that's NOT the hypotenuse. We already know both those sides, so let's solve the equation:
26 is the answer. Remember, the opposite of squaring is taking the square root.
Hope this helped!
Answer:
a_s=4.8\times 10^{-2}~m^2
Explanation:
Given:
cross-sectional area of the bone, a=4.8 \times 10^{-4} ~m^2
the factor of up-scaling the dimensions, s=10
Since we need to find the upscaled area having two degrees of the dimension therefore the scaling factor gets squared for the area being it in 2-dimensions.
The scaled-up area is:
a_s=a\times s^2
a_s=[4.8 \times 10^{-4}]\times 10^2
a_s=4.8\times 10^{-2}~m^2
Answer:
a=63
