Find the mean median mode and range. 5, 8, 11, 13, 14, 15

mean-11

mode-none

range-10

median-12

Step-by-step explanation:

Mean= 11

Median= 12  (is between 11 and 13, equally spaced)

Mode= No mode (all numbers appear the same amount of times)

Range= 10

Step-by-step explanation:

Mean= Average- sum of all numbers in the data set divided by total amount of numbers included.

Median= middle number (when in order of value)

Mode= number that occurs the most

Range= space between largest and smallest number

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
