124
Step-by-step explanation:
A triangle is BH/2
6.2 is the height and 5 is the base
one triangle is 15.5 so multiply it by 8 since its an octagon
925 ÷ 8
9 ÷ 8 = 1 r1
put 1 before the 2 = 12
12 ÷ 8 = 1 r 4
4 before 5 = 45
45 ÷ 8 = 5 r 5
So it's 115 r 5
115 and 5/8 refered
Answer: 453
Step-by-step explanation:
To solve the question, we have to calculate the margin of error which will be:
= (61.7% - 52.3%) / 2
= 9.4% / 2
= 4.7%
4.7% = 1 / ✓n
0.047 = 1 / ✓n
✓n = 1 / 0.047
✓n = 21.28
Square both sides to.gwt the value of n
n = 21.28²
n = 452.69
n = 453
