The opportunity cost of any decision is what is given up as a result of that decision. Opportunity cost includes both explicit costs and implicit costs. The firms economic profits are calculated using opportunity costs. Accounting profits are calculated using only explicit costs.
Answer:
∠C = 159°
∠D = 21°
Explanation:
∠C + ∠D = 180 (1)
∠C = 33 + 6∠D (2)
Substituting (2) to (1):
180 = 33 + 6∠D + ∠D
= 33 + 7∠D
180 - 33 = 7∠D
147 = 7∠D
<u>21 = ∠D</u>
If ∠D = 21,
∠C + 21 = 180
∠C = 180 - 21
<u>∠</u><u>C</u><u> </u><u>=</u><u> </u><u>159</u>

Answer:
confidence coefficient for 99% is 2.58
2.58 * 19.4/sqrt(n) = 0.04
2.598*19.4/0.04 = sqrt(n)
( 2.598*19.4/0.04)^2 = n
1587676
---------------------------------------------------------------------------
confidence coefficient for 90% is 1.64
(1.64*19.4/0.04)^2 = 632661.16
