Step 1
Since each LED bulb costs $6.95 and you have 100 lamps, multiply the cost per bulb by the number of lamps to find the total cost for the bulbs. \[ \text{Total cost for bulbs} = 6.95 \times 100 = 695 \] Show more…

The physical plant at the main campus of a large state university recieves daily requests to replace florecent lightbulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 45 and a standard deviation of 4. Using the 68-95-99.7 rule, what is the approximate percentage of lightbulb replacement requests numbering between 41 and 45?

10 (Venn Diagram) study has studied three Symptoms of COVID-19 patients: Symptom A - Having fever, Symptom B - Having dry cough, Symptom C - Having sore throat. Suppose all three symptoms are independent and the probability of Symptoms A and B are 0.6 and 0.4 respectively. Draw the corresponding Venn diagram. Determine the following probabilities: - Patient with high fever but no dry cough nor sore throat. - Patient with none of these three symptoms. - Patient has high fever given that she has no dry cough. - Patient has no dry cough given that she has no high fever.

Suppose that the lifetimes of light bulbs are approximately normally distributed, with a mean of 57 hours and a standard deviation of 3.5 hours. With this information, answer the following questions. (a) What proportion of light bulbs will last more than 60 hours? (b) What proportion of light bulbs will last 52 hours or less? (c) What proportion of light bulbs will last between 59 and 62 hours? (d) What is the probability that a randomly selected light bulb lasts less than 46 hours? (a) The proportion of light bulbs that last more than 60 hours is [ ]. (Round to four decimal places as needed.)
