Frame an expression for the given statements :(i) The sum of 6 and x.(ii) 3 more than a number y.(iii) One-third of a number x.(iv) One-half of the sum of number x and y.(v) Number y less than a number 7.(vi) 7 taken away from x.(vii) 2 less than the quotient of x and y.(viii) 4 times x taken away from one-third of y.(ix) Quotient of x by 3 is multiplied by y.

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.
