Suppose that X is a vertical segment that lies on the y-axis with its beginning at origin and ending at the point (0,4). Then the length of this segment is 4 units.
If you vertically compress this segment by factor of 1/4 with the centre of compression at the origin, you recieve a segment that also lies on the y-axis with its beginning at origin and ending at the point (0,1) (the length of this image segment is 1 unit).
So, the question is: if a segment that lies on the y-axis with its beginning at origin and ending at the point (0,4) is vertically compressed <span>by factor of 1/4 with the centre of compression at the origin, what is the image of this transformation?

Answer:
im gonna guess d?
Step-by-step explanation:
cuz it goes up
Answer:
The right option is:
b. There is enough evidence to conclude the mean difference in pulse rates before and after the 5 minute waiting period is different from 0.
Step-by-step explanation:
The null hypothesis is the opposite to the claim that the researchers are trying to prove. In this case, it will state that there is no difference in the mean pulse rates or, in other words, that the mean difference in pulse rates before and after the 5 minute waiting period is 0 (μ=0).
The claim of the researchers, that will be expressed in the alternative hypothesis, is that the mean difference in pulse rates before and after the 5 minute waiting period differs from 0 (μ≠0).
If the null hypothesis is rejected, is because the test shows that there is enough evidence to support the claim that the mean difference in pulse rates before and after the 5 minute waiting period differs from 0 (true alternative hypothesis).
Note: If the null hypothesis wasn't rejected, the conclusion would have been that there is no evidence o support the claim that the mean difference in pulse rates before and after the 5 minute waiting period differs from 0.
The right option is:
b. There is enough evidence to conclude the mean difference in pulse rates before and after the 5 minute waiting period is different from 0.
Answer:
<em>6 miles</em>
Step-by-step explanation:
From the question, we are told that 12 miles represents 2 inches on the map.
We are to calculate the amount of miles 1 inch will represent. To do this you will say:
12 miles = 2 inches
x miles = 1 in
Cross multiply;
2 * x = 12 * 1
2x = 12
x = 12/2
x = 6
<em>Hence 1 inch will represents 6 miles on the map</em>
