<span>Through specialization, both producers and consumers benefit. On the producer side, specialization allows producers to best use their resources in the most efficient manner possible by playing to their strengths, thus maximizing profit. On the consumer side, the fact that producers are specialized and thus efficient in their production ensures lower production costs than if products were made by less-specialized producers, translating into lower consumer-facing prices.</span>
Answer:
6ax+9ay−2bx−3by
Explanation:
2x(3a−b)−3y(b−3a)
Distribute:
=(2x)(3a)+(2x)(−b)+9ay+−3by
=6ax+−2bx+9ay+−3by
It is known as improvisation.
Answer:
0.0139
Explanation:
Given that:
The number of sample (n) = 21
The sample distribution has mean (μ) and a standard deviation of σ/√n
The z score is given as (x - mean)/ standard deviation
x = 94.8 wpm, let us assume that σ = 10 and μ = 90
Therefore: z = (x - μ) / (σ/√n) = (94.8 - 90) / (10/√21) = 2.2
To calculate the probability using Z table:
P(X>94.8) = P(Z>94.8) = 1 - P(Z<94.8) = 1 - 0.9861 = 0.0139
The probability is low that is less than 0.05, the program is more effective than the old one.
