Answer:

  1.  (B)  73

  2. r = 15

Step-by-step explanation:

1. The sum of angles in a triangle is 180°.

  62° +45° +k° = 180

  k = 180 -107

  k = 73

__

2. The sum of exterior angles of any polygon is 360°.

  4r° +7r° +5r° +8r° = 360°

  24r = 360 . . . . . . . . . . . . . collect terms, divide by °

  r = 360/24 . . . . . divide by 24

  r = 15

The number of social media post of Noami has a greater spread when compared to that of Amir.

<h3 /><h3>What is the range and intequartile range of the social media posts?</h3>

Range is the difference between the highest and lowest values of a set of observations

Range = highest value - lowest value

  • The range of Amir's social media posts = 19 - 15 = 4
  • The range of Noami's social media posts = 10 - 0 = 10

The inter quartile range is the difference between the third quartile and the first quartile of a data set.

IQR = Q3 - Q1

The IQR of Amir's social media posts: 7

The IQR of  Naomi's social media posts = 10

Answer:

1.) -t (r - s)

   -3 (-6 - 3)

   16 + 6

   <u>22</u>

2.) B

   A linear equation consists of y = slope + y-intercept (y = mx +b). In this case, the slope will rise by 1 and run (right) by 1.

3.) I`m sorry I`m not too sure about this one

I hope the first couple helped, I`m sorry I don`t know the last one.
