Answer:
area of Jonah's backyard is, 196 meter square
Step-by-step explanation:
Perimeter(P) of square is given by:
where a is the side of thew square
As per the statement:
The perimeter of Jonah's square backyard is 56 meters
⇒
Using the perimeter formula to solve for a:
Divide both sides by 4 we have;
or
a = 14 m
Area of a square(A) is given by:
Substitute the given value of a = 14 m to get area;
Therefore, the the area of Jonah's backyard is, 196 meter square

Answer:
95% confidence interval for the mean
(6.61251, 7.38749)
Step-by-step explanation:
Step:-1
Given that a random sample 'n' = 60
Given that mean of the sample x⁻ = 7.0
Given that the standard deviation of the sample (S) = 1.5
Level of significance = 0.05
Degrees of freedom = n-1 = 60-1 = 59
t₍₀.₀₅ , ₙ₋₁₎ = 2.0010
Step(ii):-
95% confidence interval for the mean is determined by
(7.0 - 0.38749 , 7.0 + 0.38749)
(6.61251 , 7.38749)
Final answer:-
95% confidence interval for the mean
(6.61251 , 7.38749)

Answer:
(x -4)^2 = 13
Step-by-step explanation:
To solve this equation using the completing the square method;
x^2 - 8x + 3 = 0
The first step is to take +3 to the right-hand side of the equation, 3 becomes negative when it crosses over the equality sign.
The equation becomes;
x^2 - 8x = -3
The next step is to add square of half of the coefficient of x to both-side of the equation. That is; you will add (-4)^2 to both-side of the equation.
x^2 - 8x + (-4)^2= -3 + (-4)^2
Then, we factorize the left hand side of the equation and our equation
(x - 4)^2 = -3 + (-4)^2
The we simplify the right-hand side of the equation
(x - 4)^2 = -3 + 16
(x - 4)^2 = 13
