Answer:
x = - 9, x = - 4
Step-by-step explanation:
Set (x +)(x + 9) equal to zero, that is
(x + 4)(x + 9) = 0
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x + 9 = 0 ⇒ x = - 9
Thus
x = - 9, x = - 4

Answer:
The answer is D, The objects have the same temperature.
Usually, if two objects are touching each other, the one with the higher temperature may transfer heat to the other object by a method called conduction. During this process, the one with the higher temperature loses heat, while the cooler one gains heat. Their temperature will change until they both have the same temperature, and this can be called thermal equilibrium.
As in "equilibrium", this word means same/balanced, and "thermal" is heat, so size is not related, and changing temperature also does not match with these 2 words. Therefore, the answer should be D.
Step-by-step explanation:
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
