Answer:

AC = 10

Step-by-step explanation:

We can apply the properties of two secants intersecting outside a circle

(see attached for reference).

in our case, our formula will be

BC (BC + AB)   = CD  (CD + DE), which can be written as:

BC · AC = CD · CE

We are given:

BC = 6, DC = CD = 5, CE = 12

simply substitute the known values into the equation above

6 · AC = 5 · 12

AC = (5)(12) / 6

AC = 10

Maria tests the effectiveness of an anti-depression drug by recruiting 500 participants and randomly assigning half e participan
Nady [450]

Answer:

D. The small p value and the small effect size suggest that the observed difference between the drug placebo groups are likely to be due to sampling error. This study should be replicated with a larger sample size.

Step-by-step explanation:

The p value is determined for any test before making a conclusion. If the p-value is smaller than critical value then we reject the null hypothesis which means that drug is not effective for the reducing depression. A very small p-value usually lesser than 0.05 indicates strong evidence against the null hypothesis.
