A Because two points determine a line, you can draw altitude BD perpendicular to AC,
which has height h. By the definition of a sine ratio,
which can be
rearranged intoa sin C = h. The formula for the area of a triangle is Area = bh. Use the
substitution property of equality to get
which rearranges into
by the commutative property of multiplication
sin C = i
sin C=
Area = b (a sin C)
Area =
b(a sin C)
his
Area =
= }(sin C)6
Area =
ab (sin C)
Area =
jab (sin C)
Area
1b (sin C)

Which of the following answers is 5/25 simplified? 1/5 5/5 2/5 1/25

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.
