At one point in an artery the velocity of blood is 5 cm/s and the diameter is 0.33 cm. If the velocity of blood at a different section, of the same artery, is 10 cm/s, what is the diamete of the artery in this section? Give numerical answer in cm and include at least 3 decimal places.

In a study of high school students at least 16 years of age, researchers obtained survey results summarized in the accompanying table. Use a 0.05 significance level to test the claim of independence between texting while driving and driving when drinking alcohol. Are those two risky behaviors independent of each other? Click the icon to view the table of survey results. Determine the null and alternative hypotheses. Ho: H₁: Determine the test statistic. x² = (Round to two decimal places as needed.) Determine the P-value of the test statistic. P-value = (Round to three decimal places as needed.) Do the results suggest that texting while driving and driving while drinking are related? O A. Reject the null hypothesis. There is sufficient evidence at a 0.05 significance level to warrant rejection of the claim of independence between texting while driving and driving while drinking alcohol. Those two risky behaviors appear to be somehow related. B. Reject the null hypothesis. There is…
