Each pair of polygons is similar. Write a similarity statement for the polygons. Then, find the measure of x, the measures of the indicated sides, and the scale factor. CB and AB

a
; x = 0.2; CB = 2.8; AB = 2.2; 1
b
; x = 0.2; CB = 2.2; AB = 2.8; 1
c
; x = 0.02; CB = 2.8; AB = 2.2; 1
d
; x = 2; CB = 0.2; AB = 0.8; 1

Susie wants to take her friend out for lunch.she wants to spend $9.75 each person. how much will she spend in all.

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.

Someone which statements are true? check all that apply.
