A) Show that the equation x3 + 6x - 5 = 0 has a solution between x = 0 and x = 1 b) Show that the equation x3 + 6x – 5 = 0 can be arranged to give x =
5
X2 + 6
by filling in the boxes. x3 + 6x -5 = 0
x3 + 6x =
X =
(x2 + 6) =
5
x2 + 6
c) Starting with x = 0, use the iteration formula xt1 =
5
X,2 + 6
twice,
to find an estimate for the solution of x3 + 6x - 5 = 0

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.
