216/10 = 21.6 = 22
22 x 3.99 = 87.78
22 x 4.99 = 109.78
216 x 1.00 = $216
87.78+109.78 = 197.56
216 - 197.56 = 18.43
Your profit will be $18.43
We have the following data:
Margin of Error = E = 2.7 % = 0.027
Sample size = n = 900
Proportion of adults in favor = p = 60% = 0.6
We need to find the confidence level. For this first we need to find the z value.
The margin of error for a population proportion is given as:

Using the values, we get:
As, seen from the z table, z=1.65 corresponds to the confidence level 90%. So, the answer to this question is option B

Step-by-step explanation:
7.
roots=-2,-1,1,3
critical points=(-1.5,-3),(0,6),(2,-13)
absolute minimum=-13
End behavior :approaches +infinity
Relative max=6 at (0,6)
Relative min. =-3 at (-1.5,-3)
and -13 at (2,-13)
interval of increase=(-1.5,0)∪(2,∞)
interval of decrease=(-∞,-1.5)∪(0,4)
8.
roots=-1,2
critical points=(0.5,10.5),(4,-10.5)
Abs.max/abs.min=not defined
End behavior:-∞ to +∞
Relative max=10.5
Relative min=-10.5
interval of increase=(-∞,0.5) ∪ (4,∞)
interval of decrease=(0.5,4)
The area of the given square pyramid is:
total area = 1,100 inches squared.
<h3 /><h3>
How to get the area of the pyramid?</h3>
On the second image, we can see that the pyramid is conformed of a square base and 3 triangles.
To get the surface area of the pyramid, we can just get the area of each of these simpler parts.
The base is a square of 22 in by 22 in, then the area of the base is:
B = (22in)*(22 in) = 484 in^2
For each triangle, the area will be:
A = (base side)*(height)/2
A = (22in)*(14in)/2 = 154 in^2
And we have 4 of these triangles, then the total area of the pyramid will be:
total area = B + 4*A = 484in^2 + 4*(154 in^2) = 1,100 in^2
