The members of Ms. Wilson’s quiz bowl team earned the scores listed below in the past 6 competitions they attended. 82, 76, 94, 71, 68, 89 Which measure BEST summarizes all of the team’s scores? mean mode range variance

Variance is the measure best summarizes all of the team’s scores

Step-by-step explanation:

The members of Ms. Wilson’s quiz bowl team earned the scores listed below in the past 6 competitions they attended:

82, 76, 94, 71, 68, 89

Mean = The mean is the average of the numbers

Mode=The number which appears most often in a set of numbers.

Range : Range is the difference between the lowest and highest values.

Variance :A measure of how spread out numbers are

So, By definitions we can say that Variance is the measure best summarizes all of the team’s scores

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
