Answer:
AB = 3.3 cm
Step-by-step explanation:
The formula to find out area of a regular octagon is given by
where a is the length of each side of the regular octagon.
Plugin A=54 into the formula
Divide both sides by 2
Plugin √2 as 1.41
Divide both sides by 2.41
Taking square root on both sides
a = 3.346
a = 3.3 cm (rounded to nearest tenth)
so, length of side AB = 3.3 cm

Answer:
This system of equations was solved the Reduction Method:
Step 1: Multiply the equations by the appropriate numbers (The first equation was multiplied by 5 and the other one bye 7), so that one of the variables disappears by subtracting both equations.
Step 2: The equations were algebraically added and one of the variables disappeared (Resulting in 31a= 217).
Step 3: The variable "a" was cleared to know its value (a= 217/31= 7).
Step 4: The value "a" obtained is substituted in one of the previous equations.
Step 5: Multiply the 2 (coefficient of "a" in the first equation) by the value "a" obtained (2x7= 14).
Step 6: The independent term "14" is passed to the right member and his sign changes to negative (-14)
The final step is to clear variable "b" to know its value (b= -17/4= -2).

Hello from MrBillDoesMath!
Answer:
B = 67.4 degrees (approximately)
Discussion:
From plane trigonometry
sin(B) = side opposite angle B \ hypotenuse
= 12/13
Use a calculator (take the inverse sine of 12/13) gives
B = 67.4
Thank you,
MrB
Answer:
The correct answers are:
1. No, because it does not lead the respondent to any particular answer (D)
2. The original question is not biased (D)
Step-by-step explanation:
In developing survey questions, response biases are tendencies for respondents to respond inaccurately or falsely to a particular question and this largely has to do with the way the questions are framed. Biased questions build preconceived thoughts in the mind of the respondent, increasing the tendency for them to lean towards a particular answer.
In this example, the question "How often do you eat fruit during an average week?" is not biased because it does not suggest to the respondent whether eating fruits is good or bad, it just directs the respondent to a particular number, hence the question is not biased.
