Answer:
Yes. There is sufficient eveidence to support the claim that Wilmington resident's earn more than the national average
Step-by-step explanation:
Given the following;
#We set our hypothesis as:
The rejection region of either hypothesis:
, we determine the critical values for this probability in the T distribution table;
=>We reject for all values greater than 1.833, t>1.833.
#We now determine the value of the test statistic as:
We find that:
Hence, there is sufficient eveidence to support the claim that Wilmington resident's earn more than the national average.
The relationship between segment AC and segment A double prime C double prime is AC = A''C'' /2.
<h3>What is a Scale Factor ?</h3>The ratio by which the new image is bigger or smaller than the original image is the scale factor.
It is given that
Triangle A″B″C″ is formed using the translation (x + 0, y + 2)
and the dilation by a scale factor of 2 from the origin.
coordinate plane with triangle ABC at A (- 3, 3), B (1, - 3), and C (- 3, -3).
segment AC is equal to A''C'' over 2
Scale factor = 2
The coordinates are
A (- 3, 3), B (1, - 3), and c (- 3, -3) is translated using (x + 2, y + 0),
new coordinates
A'(- 1, 3), B'(3, - 3), and C'(- 1, -3).
The dilation by a scale factor of from the origin
A″ (-2, 6), B″ (6, -6) and C″(-2, -6)
By the distance formula
AB =
A''B'' = = 2
Therefore
AB = A''B'' /2
Similarly AC = A''C'' /2
The relationship between segment AC and segment A double prime C double prime is AC = A''C'' /2.
