Answer:
The answer is none triangle
Step-by-step explanation:
we know that
The sum of internal angles of a triangle must be equal to
In this problem we have three angles, each measuring
so
The total sum of the three angles is equal to
therefore
The answer is none triangle
10% of 75 is 7.5
1% of 75 is .75
.1% of 75 is .075
.5 of 75 is .375
116100 will be 90% of the selling price
The will need to sell for 116100 / 90 x 100 = $129000
Standard deviation = √(n * p * q)
You are given n and p
q = 1 - p
q = 1 -0.2 = 0.8
Standard deviation = √(21 * 0.2 * 0.8)
=√3.36 = 1.83
The answer is A.
