Answer:

141 degrees.

Step-by-step explanation:

This is a seven sided polygon so first we work out the total value of the interior angles from the formula:

Total angles = 180(n - 2)

= 180 * (7-2)

= 180 * 5

= 900 degrees.

Therefore x = 900 - (122+125+148+107+126+131)

= 900 -  759

= 141 degrees.

Rainbow [258]

Answer: The value of the center increases and the distribution has a smaller spread.

Step-by-step explanation:

Re - arranging the first value in ascending order , we have :

12 ,14, 16 , 19, 21 , 22 , 28 , 32

Median = 19 + 21 / 2

            = 40/2

            = 20

Also calculating the standard variation in order to know the spread , we need to first of all calculate the mean

Mean = 12 + 14 + 16 + 19 + 21 + 22 + 28 + 32  / 8

Mean = 164/8

Mean = 20.5

Therefore to calculate the standard deviation, we need to calculate the variance, which  is

(12-20.5)^{2} +(14-20.5)^{2} + (16-20.5)^{2} + (19-20.5)^{2} + (21-20.5)^{2} + (22-20.5)^{2} + (28-20.5)^{2} + (32-20.5)^{2}  / 8

Variance = 328/8

Variance = 41

Standard deviation = \sqrt{variance}

S.D = \sqrt{41}

S.D = 6.4

Also re arranging the second values , we have :

20 , 24 , 25 , 31

Median = 24 + 25 / 2

Median = 49/2

Median = 24.5

Calculating the S.D using the same format , the S.D = 3.9

Comparing the two we can conclude that the value at the center increases and the distribution has a smaller spread

What is the measure of the missing angle
Dmitrij [34]

Answer:

115 degrees

Step-by-step explanation:

first find the missing angle in the triangle

75+40+x=180

x+115=180

x=65

That angle plus the ? angle form a straight line, meaning they add up to 180 degrees.

so 65+x=180

x=115
