Answer:
6
Step-by-step explanation:
Given information:
Interior angle of a polygon cannot be more that 180°.
One interior angle =
Other interior angles are =
Let n be the number of sides of the polygon.
Sum of interior angles is
Combine like terms.
.... (1)
If a polygon have n sides then the sum of interior angles is
.... (2)
Equating (1) and (2) we get
Isolate variable terms.
Divide both sides by 52.
Therefore the number of sides of the polygon is 6.
Answer:
7/9 which is the opposite of 2/9
Step-by-step explanation:
Answer:
0.5 : 0.75
Step-by-step explanation:
because 1/2 is .5 in decimal form and 2/3 is .75 in decimal form
<h3>
Answer: 3/56</h3>
========================================================
Work Shown:
A = event of picking the "2" card
P(A) = probability of event A happening
P(A) = 1/8
This is because there is one card labeled "2" out of 8 cards total
-------
B = event of picking a number less than 6, given event A has happened
P(B) = 3/7
There are 3 cards less than 6 (those cards are labeled 3,4, and 5) out of 8-1 = 7 cards left over. We havent put the first card back so that's why 8 drops to 7. We also don't consider the "2" card. So that's where the 3/7 comes from.
-------
P(A and B) = P(A)*P(B)
P(A and B) = (1/8)*(3/7)
P(A and B) = (1*3)/(8*7)
P(A and B) = 3/56
The internal rate of return of this investment is 8%.
If the hurdle rate is 7%, the investment should be invested in.
<h3>What is internal rate of return?</h3>
Internal rate of return is a capital budgeting method that determines the the discount rate that equates the after-tax cash flows from an investment to the amount invested
If the internal rate of return is greater than the hurdle rate, the investment should be undertaken. If this is not the case, the investment should not be invested in.
IRR can be calculated with a financial calculator
Cash flow in year 0 = $-29,480
Cash flow each year from year 1 to 4 = 8900
IRR = 8%
