Theorem: The measure of an angle formed by two lines that intersect outside a circle is half the difference of the measures of the intercepted ares. 1. In the diagram below of cirele 0, PAC and PBD are secants. If mCD- 70 and mAB - 20, what is the degree measure of ZP? 2. In the accompanying diagram of circle 0, PC is a tangent, PBA is a secant, mAB = 132, and mCB = 46. Find mLP 3. In the diagram below, tangent DA and secant DBC are drawn to cirele O from external point D, such that ACa BC If mBC - 152°, determine and state mZD.

Fifty-four wild bears were anesthetized, and then their weights and chest sizes were measured and listed in a data set. Correlation Results Results are shown in the accompanying display. Is there sufficient evidence to support the claim that there is a linear correlation between the weights of bears and their chest sizes? When measuring an anesthetized bear, is it easier to measure chest size than weight? If so, does it appear that a measured chest size can be used to predict the weight? Use a significance level of a =0.05. Correlation coeff, r: 0.966175 Critical r: ±0.2680855 P-value (two tailed): 0.000 Determine the null and alternative hypotheses. H1: p (Type integers or decimals. Do not round.) Identify the correlation coefficient, r. (Round to three decimal places as needed.) Identify the critical value(s). (Round to three decimal places as needed.) A. There is one critical value at r= O B. There are two critical values at r= + Is there sufficient evidence to support the claim…
