The sides of a triangle field are 55m,300m and 300m. It's area is equal to (7/15)th area of a circular park. What is the perimeter (in m) of the circular park ( correct to one decimal place)? (Take π=22/7)

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

If tan2a=cot(a+60), find the value of a, where 2a is an acute angle

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.
