The test scores of students in a math class are 46, 40, 50, 43, 35, 41, 50, 42, 38, and 48. What is the mean of this set of data? A. 35.6 B. 40 C. 43.3 D. 50

C. 43.3

Step-by-step explanation:

The mean or average of a data set can be found by adding up all the values and dividing by the number of values.

1. Add up all the values

The values:  46, 40, 50, 43, 35, 41, 50, 42, 38, 48

Add them together:  46 +40+50+ 43+35+41+50+ 42+38+48

433

2. Divide by the number of values

Count how many numbers are in the set of data.

Data Set: 46, 40, 50, 43, 35, 41, 50, 42, 38, 48

10 values

Divide 433 by 10

433/10

43.3

The mean of the set of data is 43.3 and the correct answer is C.

43.3

Step-by-step explanation:

I added up all the numbers and divided by the number of numbers.

answer: an 8-foot rope is tied from the top of a pole to a

stake in the ground, as shown in the diagram

below

step-by-step explanation:

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.
