Answer:
1/3
Step-by-step explanation:
The scale factor is the ratio of image lengths to original lengths.
B'C' = 1 unit
BC = 3 units
The scale factor is B'C'/BC = 1/3.
_____
<em>Additional comment</em>
The center of dilation in this figure is 3 units below D' on the same vertical line. (It is 1 unit off the bottom of the grid shown.)
Answer:
The answer is c
Step-by-step explanation:

<h2><u>
Answer with explanation:</u></h2>
Let be the population mean strain in a way that conveys information about precision and reliability.
The sample mean is the best point estimate of the true population mean .
As per given , we have
Sample size : n= 12
degree of freedom :
Sample mean :
The true average strain in a way that conveys information about precision and reliability= 25.0
sample standard deviation : s= 3.3
Significance level :
Since sample population standard deviation is unknown , so we use t-test.
Critical t-value for t :
95% Confidence interval for true average strain in a way that conveys information about precision and reliability:
The 95% Confidence interval for true average strain in a way that conveys information about precision and reliability:
We 95% confident that the true population average strain in a way that conveys information about precision and reliability lies between 22.9 and 27.1 .
