HELP ASAP!! K12 / KEYSTONE QUESTION! I WILL GIVE BRAINLIEST!! HELP!

1. Find the balance point for the points 0.4, 1.4, and 1.8.

2. Which measure of center is indicated by the center of balance, the median, the mean, or the mode?

3. Define what is meant by “measure of center.”

If you don't know the answer then please don't answer, this is appreciated!

A) mean = 1.2

B) median

C) The measures of center use data points to approximate a middle value or average of a given data set

Step-by-step explanation:

The “balance” process was developed to provide another way in which the mean characterizes the “center” of a distribution. 

The mean is the balance point of the data set when the data are shown as dots on a dot plot (or pennies on a ruler). 

A) The balance point for the points 0.4, 1.4, and 1.8. Will be

(0.4 + 1.4 + 1.8)/3 = 3.6/3 = 1.2

B) The median is the measure of center that is indicated by the center of balance

The median is the value in the center of the data. Half of the values are less than the median and half of the values are more than the median. It is probably the best measure of center to use in a skewed distribution.

C) A measure of central (measure of center tendency) is a value that describe a set of data by identifying the central position of the data set. The three measures of central tendency are the mean, median and mode.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
