Mr. Rodriguez included his age into the data set. The new data set is listed below.
12, 11, 13, 13, 12, 13, 12, 13, 13, 12, 35

After including his age to the data the mean absolute value changed to 3.8

a. Explain how a mean absolute value of 3.8 differs from the mean absolute value found in question 2.

b. Explain the meaning of the mean absolute deviation as it relates to the age of all the people in the class.

20+ ! come and answer quick! triangle mno is reflected over the x-axis and then translated up 4 and right 3. how can the transformation be amended such that the translation can occur before the reflection and have the image remain in the same position? a translate the pre-image down 4 and right 3 and then reflect the figure over the x-axis. b translate the pre-image up 3 and right 4 and then reflect the figure over the x-axis. c translate the pre-image up 4 and left 3 and then reflect the figure over the y-axis. d translate the pre-image down 3 and right 4 and then reflect the figure over the x-axis.

The longer leg of a 30° 60° 90° triangle is 16 times square root of three how long is a shorter leg

The standard deviation for a set of data is 5.5. the mean is 265. what is the margin of error?
