Answer:
a. Expected frequency of losses per semester = 0*0.08 + 5*0.16 + 10*0.28 + 15*0.32 + 20*0.14 + 25*0.02
Expected frequency of losses per semester = 11.7 losses per semester
b. Variance = (0-11.7)²*0.08 + (5-11.7)²*016 + (10-11.7)²*0.28 + (15-11.7)²*0.32 + (20-11.7)²*0.14 + (15-11.7)²*0.02
Variance = 10.9512 + 7.1824 + 0.8092 + 3.7848 + 9.6446 + 3.5378
Variance = 35.61
c. As losses equal $60, expected losses per semester = 11.7*$60 = $702
d. Expected losses of all textbooks per semester = 250*11.7*$60 = $175,500
The correct
answer is 156
Answer:
Triangle
Step-by-step explanation:
A triangle is a closed figure bounded by straight lines.
A triangle has three sides, three angles and three vertices.
Normally any triangle is uniquely determined by any 3 independent measures,
It may be either 2 angles one side, or two sides, one included angle, or any other detail.
By having 3 known dimensions of a triangle, to find out other unknown is known as solving a triangle.
Hence right answer is
Solving a _triangle____ is the process of calculating unknown side lengths or angle measures of a triangle if certain of the side lengths and/or angle measures are known.
