According to the given question if one of the angle of the triangle is 75 degree and the other two sides are of length 2 and 3 units respectively then option C is correct. Only One triangle can be formed where Angle B will be 40 degree. You can figure it out from the steps mentioned below first of all draw an Arc with the length either 3cm or 2 cm that will be the base of a triangle and then from the ending point again cut an arc then after from the starting point that is the point draw an angle of 75 degree with the help of protactor and extend it to meet the Arc finally you can get the 40 degree.
This is a normal distribution with the mean of 14 g/dL and a standard deviation of 1 g/dL. For less than 13 ( 13 = mean - 1 standard deviation and less ): 16 %<span> of 200, 0.16 * 200 = </span>32 people. For greater than 14 ( mean and greater ): 50 %<span> of 200 = </span>100 people.<span> </span>
The percentage of data explained by regression line is assessed using R-square. Here, in the given scenario correlation coefficient r is given. We simply take square of correlation coefficient to get r-square. r-square=(-0.72)^2=0.5184=51.84%
