5ft
Step-by-step explanation:
all sides of a square are equal and there are 4 sides so divide 20 by 4 and you get 5 ft
Answer:
AE = 4
Step-by-step explanation:
Use the formula
AE*EC = DE*EB
Since we don't know AE or EC, let AE = x and then EC will = 16 - x. The formula then becomes
x(16 - x) = 8(6)
Getting everything on one side and setting it equal to 0 will allow us to factor for x:
Factoring that gives you that
x = 4 and x = 12. That means that one of those sements has a length of 4 and the other has a length of 12. AE is shorter so it's 4 and EC = 12

it can go up and down like weight
Answer:
The margin of error is<em> 0.22</em>
Step-by-step explanation:
Mathematically, the margin of error at the given confidence interval can be calculated using the formula below;
Margin of error = × s/√n
where is the t-value at the given confidence interval, s is the standard deviation and n is the sample size
= 1.96 (From t-distribution table)
s = 2.5 inches
n = 500
MOE = 1.96 × 2.5/
MOE = 1.96 × 2.5/22.36
MOE = 0.22
