The position of a point A is defined from a point of observa-tion O by distance OA = D, and the angular deviation from a reference lineOB.The mean error in estimating the distance is 100k per cent of the distance;the mean error in estimating the angular deviation is & radians. The error madein representing the point A on a chart obeys a normal tircular distribution withmean deviation r; the error in the position of the point O also obeys a normalcircular distribution law with mean deviation R. Find the compound distribu-tion characterizing the error in position resulting from the representation ofpoint A on the chart. How will the probability that point A lies in a rectangleof size 100 x 100 sq. m. change if D decreases from 20 to 10 km. (r = 20 m.,R 40 m., & = 0.003, k 0.005) ?=

Find the indicated IQ score. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15. x 0.2525 A symmetric bell-shaped curve is plotted over a horizontal scale. A vertical line runs from the scale to the curve at labeled coordinate x, which is to the right of the curve’s center and peak. The area under the curve to the right of the vertical line is shaded and labeled 0.2525. Question content area bottom Part 1 The indicated IQ score is enter your response here.

David and Patrick are playing baseball for the Cafe Tropical team. Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 250 feet and a standard deviation of 50 feet. If X = distance in feet for a fly ball, then X ~ N ( , ) If one fly ball is randomly chosen from this distribution, what is the probability that this ball traveled less than 220 feet? Sketch the graph. Scale the horizontal axis X. Shade the region corresponding to the probability. Find the probability. P = Find the 80th percentile of the distribution of fly balls. 80th Percentile: feet
