Hi there! The answer is C.
The area of the square in the middle is the following:
Hence, the area of the square is 25 cm^2.
The area of one triangle is the following:
Hence, the total area of the four triangles is 4 × 20 = 80 cm^2.
Therefore, the total area of the pyramid is 80 + 25 = 105 cm^2. The answer is C.
Answer:
In order to find the value of s, we must isolate the s variable in this equation, so the first step should be subtracting 3 5/6 from both sides of this equation. In order to subtract, we multiply each denominator to get 42, and multiply the numerator by the same amount, and subtract the number from both sides:
s + 3 35/42 = 9 6/42
s = 5 13/42

Answer:
<em>The number of people would have participate in opinion poll</em>
<em>n = 15,267</em>
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Given data an opinion poll reported that 36% believe a certain governor broke campaign financing laws in his election campaign.
<em>Given proportion = 36% =0.36</em>
<em>Given the margin of error = 1% =0.01</em>
<em>Level of significance = 99% 0 r 0.01</em>
<em>Z₀.₀₁ = 2.576</em>
<u><em>step(ii):</em></u><em>-</em>
<em>The margin of error of Population proportion is determined by</em>
√n = 123.648
Squaring on both sides , we get
<em>n = 15,267</em>
<u><em>final answer:</em></u><em>-</em>
<em>The number of people would have participate in opinion poll</em>
<em>n = 15,267</em>
