This is a right triangle problem. Angle A is 90 degrees. Draw the triangle and label it as we did in lecture. If angle B is 64 degrees 15 minutes and side c is 332.98 feet, what is the distance in feet of side b? Give your answer to two decimal places. Do not provide units. Those are in feet – right? 1 points QUESTION 5 1. This is a right triangle problem with angle A being the 90 degree angle. It should look like the one from lecture. If angle B is 31 degrees 10 minutes and side c is 312.86 feet, what is the distance to two decimal places of side a? Give your answer to two decimal places. Do not provide units – those are in feet. 1 points QUESTION 6 Ad by Browse Safe | Close 1. It is desired to determine the height of a flagpole. Assuming that the ground is level, an instrument is set up 216.46 feet from the flagpole with its telescope centered 4.92 feet above the ground. The telescope is sighted horizontally to a point 4.92 feet from the bottom of the flagpole and then the angle at the instrument looking to the top of the pole is measured. That angle is 25 degrees 34 minutes. How tall is the flagpole from its base? Give your answer to two decimal places with NO units. 1 points QUESTION 7 1. You are hiking in the mountains. For every 100.00 feet you would be walking horizontally, you have increased your elevation by 4.6 feet. At what grade are you climbing? Give your answer to three decimal places. Hint: Your units will be in ft/ft. 1 points QUESTION 8 1. A grade of 0.4 percent is being considered for a mountain roadway. The elevation at the initial point is 2,054.23 feet and a horizontal distance of 5,758.79 needs to be covered. What is the elevation at the end of the grade? 1 points QUESTION 9 1. A slope distance was measured between two points (A and T) and determined to be 3,307.97 feet. At point A the elevation is 872.17 feet and at point T the elevation is 884.21 feet. What is the horizontal distance between A and T? 1 points

Question 2 (1 point) Which of the following is correct about interpreting the results of statistical tests? Question 2 options: 1) Obtaining a probability value of .05 tells us the difference between groups is definitely not caused by chance fluctuation. 2) If a probability value falls above .05, then the results will have to be replicated before we can have confidence in them. 3) Obtaining a probability value of .05 gives us confidence that the findings are not the result of chance, but does not eliminate this possibility. 4) A .05 probability value means there is a 5 percent chance the finding reflects a real difference. Question 3 (1 point) Which of the following statements is true about theories of personality? Question 3 options: 1) They provide only a part of the picture of human personality. 2) They support the expert’s viewpoint. 3) Theories are predicted from one hypothesis or another. 4) They are directly tested using empirical methods. Question 4 (1 point) Which of the following statements is correct about hypothetical constructs? Question 4 options: 1) They are useful inventions by researchers that have no physical reality. 2) They are easier to measure than personality variables. 3) They cannot be measured with personality tests. 4) They have poor reliability and validity. Question 5 (1 point) According to the “law of parsimony,” Question 5 options: 1) a good theory generates a large number of hypotheses. 2) the best theory is the one that explains a phenomenon with the fewest constructs. 3) hypotheses are generated from theories. 4) theories should require as few studies as possible to support them. ________________________________________ Question 6 (1 point) Which of the following does a correlation coefficient not tell us? Question 6 options: 1) If the difference between two means reflects a real difference or can be attributed tochancefluctuation. 2) The strength of a relationship between two measures. 3) The direction of a relationship between two measures. 4) How well a score on one measure can be predicted by a score on another measure. Question 7 (1 point) A researcher finds that males make fewer errors than females when working in a competitive situation. However, women make fewer errors than men when working in acooperative situation. This is an example of Question 7 options: 1) a confound. 2) two manipulated independent variables. 3) an interaction. 4) a failure to replicate.
