- State the number of significant digits and the implied precision of the given number. The number 1.928×10^4 has........ significant digits (type a whole number) B. What is the implied precision of the number 1.928×10^4 s? A. The number is precise to the nearest hundred seconds B. The number is precise to the nearest second. C. The number is precise to the nearest ten secondsExplain the difference between a rate of change that is positive and one that is negative. Give an example of each. O Consider the ordered pair (x, y) where x is the independent variable and y is the dependent variable. If y increases with the increase in x, then the rate of change of y is positive. Whereas, if y decreases as x increases, then the rate of change is negative. For example, if you consider the speed of a car (y) over time (x), as the car accelerates, the speed increases with increasing time, and the rate of change of its speed is positive. When the car brakes, the rate of change of its speed is negative, because the speed decreases over time. Consider the ordered pair (x, y) where x is the independent variable and y is the dependent variable. If y increases with a decrease in x, then the rate of change of y is positive. Whereas, if y decreases as x decreases, then the rate of change is negative. For example, if you consider the speed of a car (y) over time (x), as the car…Question 2: Complete the following Error Analysis The lengths of the sides of a rectangular box are measured using a ruler marked with a millimeter scale.

- The minimum number of lighting fixtures in an Auditorium library was calculated to be 250 luminaires (in accordance with the BZ method). The lighting fixtures used are 1x22-Watt LED (The lumens output of each LED lamp is 3000 lumens). The Utilization factor was found to be 0.55. What is the area of the Auditorium library? Assume a reduction factor of 1 and a depreciation factor of 1.5. Select one: 1100 m² O O 275 m² 40900 m² 550 m²Find the uncertainty in a calculated average speed from the measurements of distance and time. Average speed depends on distance and time according to this function v(t,x) = x/t. Your measured distance and time have the following values and uncertainties x 3 meters, x =0,1 meters and t 1.8 seconds and 5t = 1.5 seconds. What is the uncertainty in the average speed, bV ? Units are not needed in your answer.Let µ be the average of the random variable x. Then the quantities (xi − µ) are the deviations of x from its average. Show that the average of these deviations is zero. Hint: Remember that the sum of all the pi must equal 1.
