6. Determine whether the triangles are similar. If so, write a similarity statement and name the postulate or theorem you used. If not, explain.
W
V
D
+
Choose the correct answer below:
A. Yes, ASCW - AVCD because ZS. V and WC = $c. Thus, the triangles are similar
by the SAS similarity theorem.
B. Yes, ASCW - AVDC because HC = $C = WS. Thus, the triangles are similar by the SSS
similarity theorem.
C. Yes ASCW - AVCD because ZS = V and ZSCW - ZVCD. Thus, the triangles are
similar by the AA postulate.
D. No, the triangles are not similar because no
theorem or postulate can be satisfied.

Arandomized controlled trial is designed to evaluate the effect of metoprolol in patients with heart failure. while preparing for statistical analysis, the researcher reviews some common types of statistical errors. which of the following statements is true regarding a type i error in a clinical study? a. the study is not significantly powered to detect a true difference between study groups. bthe null hypothesis is true but is rejected in error. c. the null hypothesis is false but is accepted in error. d. type i error is also known as beta and is usually 0.1 or 0.2. e. type i error depends on the study's confidence interval.
