The mode is the number that appears the most often.
1 appears twice
3 appears three times
4 appears once
6 appears once
8 appears once
9 appears four times
Answer:
c. x = 0
Step-by-step explanation:
2(x-3)+9=3(x+1)+x
⇔
2x - 6 + 9 = 3x + 3 + x
⇔
2x + 3 = 4x + 3
⇔
2x = 4x
⇔
4x - 2x = 0
⇔
2x = 0
⇔
x = 0
Answer:
900°
Step-by-step explanation:
What is the sum of the measures of the interior angles of a 7-gon?
The formula to measure the interior angles of a polygon
= (n- 2) × 180 °
Where,
n = number of sides
We are given 7 - gon
This means it has 7 sides = Heptagon
Hence,
The measure of the interior angle is given as:
(7 - 2) × 180°
= 5 × 180°
= 900°
The sum of the interior angles of a 7-gon is 900°
Whole numbers is the correct answer
