((MATHS FORM2 CHAPTER 5 CIRCLE)). HELP I WILL MARK AS BRAINLIEST PLEASE SHOW YOUR WORKING :-) Kevin wants to build a dartboard. The dartboard consists of two
circles centred at O and three shaded regions as in the diagram.
The diameters BOD and AOC are perpendicular to each other.
Given OE= ED = 10 cm. Calculate the area of the shaded regions
22
in cm². ((Use π= 22/7))​

(co 3) the soup produced by a company has a salt level that is normally distributed with a mean of 5.4 grams and a standard deviation of 0.3 grams. the company takes readings of every 10th bar off the production line. the reading points are 5.8, 5.9, 4.9, 6.5, 5.0, 4.9, 6.2, 5.1, 5.7, 6.1. is the process in control or out of control and why? it is out of control as two of these data points are more than 2 standard deviations from the mean it is in control as the data points more than 2 standard deviations from the mean are far apart it is out of control as one of these data points is more than 3 standard deviations from the mean it is in control as the values jump above and below the mean
