Answer:
B. 44.93
Step-by-step explanation:
The law of sines states
where a, b and c are the 3 sides of the triangle and A is the angle opposite side a, B the angle opposite side b and C the angle opposite side c
In this particular problem we have
side a = 44, angle A = 46.7
side c = ? , angle C = 48
So 44/sin(46.7) = c/sin(48) or by multiplying both sides by sin(48)
c = sin(48) * 44/sin(46.7) = 44.92937 which is 44.93 rounded to 2 decimal places
Answer:
(a) 1.8 eggs
(b) 0.52 eggs
Step-by-step explanation:
According to the problem, computation of the given data are as follows:
The mean number of broken eggs in a dozen E(X) = 0.6
Standard deviation SD(X) = 0.3
(a). For 3 dozen eggs, number of broken eggs can be calculated by using following formula,
E(X) for 3 dozen = 3 × 0.6
= 1.8 eggs
(b). Standard deviation for 3 dozen can be calculated as follows,
SD (X) = ×
=
= 0.52 eggs
