Answer:
Estimate of population 0.61
(b) Margin of error = 0.07 The real population interval estimation is ± 7%.
c). Margin of error = 0.15
d) The real population's interval estimation is ± 15%
e). Yes, the action argument of the group is based on a half-range estimation of the true population. The reason that 62% ± 15% = 47%, or 77%, while 47% is similar to 45%, as the Collective action group states.
Answer:
y-intercept: [0, -2]; 0 = m
Step-by-step explanation:
Anything set to equal <em>y</em><em> </em>is what is known as a zero <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>] because it is a horizontal line.

Answer:
![\huge\boxed{A=x^2+12x+35}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7BA%3Dx%5E2%2B12x%2B35%7D)
Step-by-step explanation:
The formula of an area of a rectangle:
![A=lw](https://tex.z-dn.net/?f=A%3Dlw)
<em>l</em><em> - length</em>
<em>w</em><em> - width</em>
We have
![l=x+7\\\\w=x+5](https://tex.z-dn.net/?f=l%3Dx%2B7%5C%5C%5C%5Cw%3Dx%2B5)
Substitute:
![A=(x+7)(x+5)](https://tex.z-dn.net/?f=A%3D%28x%2B7%29%28x%2B5%29)
Use FOIL <em>(a + b)(c + d) = ac + ad + bc + bd</em>
<em></em>
<em></em>
combine like terms
![A=x^2+(5x+7x)+35\\\\A=x^2+12x+35](https://tex.z-dn.net/?f=A%3Dx%5E2%2B%285x%2B7x%29%2B35%5C%5C%5C%5CA%3Dx%5E2%2B12x%2B35)
<span>The volume formulas for cones and cylinders are very similar: The volume of a cylinder is: π × r2 × h. The volume of a cone is: 1 3 π × r2 × h.</span>
