A uniform horizontal strut weighs 430 N. One end of the strut is attached to a hinged support at the wall, and the other end of the strut is attached to a sign that weighs 175 N. The strut is also supported by a cable attached between the end of the strut and the wall. The width of the sign is half the length of the strut and its mass is uniformly distributed. Find the tension in the cable and the force at the hinge of the strut. 30° Restaurant Image Description Figure is a schematic drawing of a sign which hangs from the end of a uniform strut. The strut forms a 30 degree angle with the cable tied to the wall above the left end of the strut. Hint 1 If an object is in static equilibrium, what can be said about the net torque and the net force? Hint 2 Review Section 12.2 Examples of Static Equilibrium. T = N Fhinge N

In a survey of 3377 adults aged 57 through 85 years, it was found that 81.3% of them used at least one prescription medication. Complete parts (a) through (c) below a. How many of the 3377 subjects used at least one prescription medication? (Round to the nearest integer as needed.) b. Suppose you have already conducted a one-tailed hypothesis test at a significance level of 0.05. Use a suitable confidence interval to construct a corresponding confidence interval estimate of the percentage of adults aged 57 through 85 years who use at least one prescription medication. %<p<% (Round to one decimal place as needed.) c. Does it seem reasonable to conclude that the true percentage is greater than 75%? A. Yes, because the interval estimate does not contain 75% B. No, because the interval estimate is entirely above 75% C. Yes, because the interval estimate is entirely above 75% D. No, because the interval estimate does not contain 75%
