Answer:
286.87m (not sure)
Step-by-step explanation:
since we are looking for the hypotenuse we are to use SIN
sin 20.4=100/x
sin 20.4= 0.3486
so 0.3486x =100
divide both sides by 0.3486
so 100/0.3486
= 286.87m approximately
3 1/4 can turn into 13/4 as an improper fraction. 2 2/3 can turn into 8/3 as a improper fraction. To multiply fractions, just multiply the top by the top and the bottom by the bottom. This yields 104/12. Divide top and bottom by 4 yields 26/3 or 8 2/3
Answer:
Answer for the question :
A resercher is wondering whehter the drinking habits of adults in a certain region of the country are in the same proportion as the general population of adults. Suppose a recent study stated that the proportion of adults who reported drinking once a week or less in the last month was 0.26. The researcher's null hypothesis for this test is H0: P=0.26 and the alternative hypothesis is Ha; P> 0.26. The researcher collected datat from a random sample of 75 adults in the region of interest.
1- Verify that the normality assumption is satisfied. Describe each separately.
2- To cotinue the study into the drinking habits of adults, the researcher decides to collect datat from adults working in "blue collar" jobs to see whether their drinking habits are in the same proportion as the general public. The null hypothesis for this test is H0: P=0.26 and the alternative hypothesis is Ha: P>0.26. The researcher computer the test statistic to be 1.59. Draw a graph of z distribution, label the test statistic and shade the p-value associated with this test statistic."
