PLEASE HELP I NEED TO PASS THIS CLASSS Consider these two triangles. Triangle A'B'C' is the
dilated figure with a scale factor of 3.

What can be concluded about the two triangles? Check
all that apply

The triangles are similar.
The corresponding sides are proportional.
The length of A'B' is 15.
The length of B'C' is 9.
The dilation is a reduction.

Arandom sample of 45 observations results in a sample mean of 68. the population standard deviation is known to be 23 a. compute the margin of error at a 959% confidence interval. b. compute the 95% confidence interval for the population mean c. compute the 90% confidence interval for the population mean. d. compute the 75% confidence interval for the population mean
