A supervisor finds the mean number of miles that the employees in a department live from work. He finds x Overbar = 29 and s = 3.6. Which mileage is within a z-score of -1.5?
Answers
The mean number of miles that the employees in a department live from work is 24.
What is a z-score?
The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
The z-score is given as
x = 29
s = 3.6
z = -1.5
Then the mean will be

Type the correct answer in the box. Rewrite the quadratic function in the form that best reveals the zeros of the function.
Answers
Answer:
f(x) = (2x + 3)(2x + 1)
Explanation:
The form that best reveals the zeros of the function is:
f(x) = (x - a)(x - b)
Where a and b are the zeros of the function.
So, we need to apply the distributive property as:
[tex]\begin{gathered} f(x)=2(2x^2+4x)+3 \\ f(x)=2\cdot2x^2+2\cdot4x+3 \\ f(x)=4x^2+8x+3 \end{gathered}[/tex]Then, we can factorize the quadratic function as:
[tex]f(x)=(2x+3)(2x+1)[/tex]So, now we can identify the zeros of the function if we solve the following equation:
[tex]\begin{gathered} f(x)=(2x+3)(2x+1)=0 \\ 2x+3=0\rightarrow x=-\frac{3}{2} \\ or \\ 2x+1=0\rightarrow x=-\frac{1}{2} \end{gathered}[/tex]Therefore, the form that best reveals the zeros in the function is:
f(x) = (2x + 3)(2x + 1)

Perimeter of rectangular dog run is 32.34 units.
Given,
Vertices of rectangular dog run are [tex](2\frac{1}{3},7\frac{1}{2} ), (12,7\frac{1}{2}), (12,1), (2\frac{1}{3},1 )[/tex]
Let

A, B,C and D be the vertices of the rectangular dog run as shown in figure.
In rectangle opposite sides are equal. thus, AB=CD and BC=AD
In this rectangle, AB is length and BC is width.
To find distance of AB and BC use formula,
[tex]Distance=\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]
[tex]AB=\sqrt{(12-\frac{7}{3} )^2+(\frac{15}{2}-\frac{15}{2} )^2} = \sqrt{(\frac{36-7}{3} )^2} =\frac{29}{3}= 9.67[/tex][tex]Bc=\sqrt{(12-12 )^2+(1-\frac{15}{2} )^2} = \sqrt{(\frac{2-15}{2} )^2} =\sqrt{(\frac{-13}{2})^2} = 6.5[/tex]
To find perimeter of rectangular dog run use formula,
[tex]Perimeter =2(Length + Width)\\\\Perimeter =2(AB+BC)\\\\Perimeter =2(9.67+6.5)\\\\Perimeter=2(16.17)\\\\Perimeter=32.34[/tex]

What is the Percentage?
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
What is Percentage change?
The percentage increase is calculated by subtracting the original number from the new number, dividing that result by the original number, and multiplying that result by 100.
where growth in number equals new number minus initial number.
Similar to how a percentage increase is calculated, a percentage reduction is calculated by subtracting a new number from the original number, dividing that new number by the original number, and multiplying that result by 100.
decreasing number where original number - new number
In other words, there is a percentage decline if the response is negative.
