Answer:
Triple the length, height and width
Answer:
15) For a regular polygon of N sides, the measure of one interior angle is:
A = (N - 2)*180°/N
In this case, the figure has 11 sides, then we have N = 11, and the measure of each interior angle will be:
A = (11 - 2)*180°/11
A = 9*180°/11 = 147.27°
Rounding to the first decimal after the decimal point, we get:
A = 147.3°
Then the correct option is B.
16) We know that the length of all the sides of a square is the same.
In the image, we can see that the length of the right side is 4, and the length of the top side is 2x + 4
And those lengths must be the same, then we have the equation:
2x + 4 = 4
subtracting 4 in each side of the equation we get:
2x + 4 - 4 = 4 - 4
2x = 0
The only solution for this equation is x = 0.
Then the correct option is C
Because when you do 3 x 2=6 and then 52-6 it doesn’t equal 20. It equals 46.
Answer:
It can be used the confidence interval to check the idea.
The confidence interval tells us that the real mean is expected to be between 40.2 and 40.4, with a 95% of confidence.
We can conclude that the mean diameter has moved away from the target value.
Step-by-step explanation:
A method to determine wether the mean diameter has moved away from the target is to calculate a confidence interval over the mean.
This would let us know if the real mean diameter could be 40 mm or not.
If the confidence interval does not include the value 40 mm, we can claim that the mean diameter has moved from the target value.
We will calculate a 95% confidence interval (CI), for which the z-value is z=1.96.
The margin of error is:

Then, the upper and lower limits of the CI are:

The confidence interval tells us that the real mean is expected to be between 40.2 and 40.4, with a 95% of confidence.
We can conclude that the mean diameter has moved away from the target value.
