Which of the following describe a set of data whose histogram approximates
a normal curve?
check all that apply.
o
a. most of the observations are near the mean of the data set.
b. the observations trail off at values far from the mean.
o
c. the histogram of the data is exactly the same as the normal
curve
o
d. the sum of the data values must be 1
e. all of the data values have to be positive.

the correct answer is 1: 2

step-by-step explanation:

hope this your welcome : )

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
