Answer: 62.

Step-by-step explanation: The mean is the average. In order to find the average, we need to add all of the numbers up, then divide by the number of quizzes. So:

20 + 40 + 40 +40 + 60 + 60 + 60 + 60 + 80 + 80 + 80 + 80 + 100 = 800

800 / 13 = 61.5, appr. 62.

Please help me I’m dying
Alex

Answer:

a° = 58°

b° = 48°

c = 74°

d° = 122°

Step-by-step explanation:

<em>Angles on a straight line add up to 180°</em>

58° + d° = 180°

d° = 180° - 58° = 122°

<em>Alternate angles are equal.</em>

a° = 58°

<em>Angles in a triangle add up to 180°.</em>

48° + 58° + c° = 180°

106° + c° = 180°

c° = 180° - 106° = 74°

<em>Angles on a straight line add up to 180°</em>

74° + 58° + b° = 180°

132° + b° = 180°

b° = 180° - 132° = 48°
