Answer:
angle G
Step-by-step explanation:
the quadrilateral did not change position or ration, it only shrank, so all the angles are in the same place and angle C = angle G
The slope of line A is m= 1/3
Answer:
The 95% confidence interval for the mean score is:
∈ 
Step-by-step explanation:
We want to estimate the population mean, that is, the average score of all the subjects.
An estimator for the population mean μ is 
Since the sample size is 
then we use the statistic 
with 
degrees of freedom
The confidence interval for the mean is:
Where
is the average score of the sample
is the standard deviation of the sample
is the sample size
for a confidence level of 95% and 26 degrees of freedom
Then confidence interval is
∈
Answer:
√2
Step-by-step explanation:
Angle ratio = 45 : 45 : 90
Ratio of side = 1 : 1 : √2
