Answer:
0.2706 ; 0.05265 ; 0.1353
Explanation:
Given that :
λ = 2
According to the poisson distribution formula :
P(x = x) = (λ^x * e^-λ) / x!
P(x = 1) = (2^1 *e^-2) / 1!
P(x = 1) = (2 * 0.1353352) = 0.2706
P(x ≥ 5) = 1 - P(x < 5)
1 - P(x < 5) = 1 - [p(x = 0) + p(x = 1) + p(x = 2) + p(x = 3) + p(x = 4)]
We obtain and add the individual probabilities. To save computation time, we can use a poisson distribution calculator :
1 - P(x < 5) = 1 - (0.13534+0.27067+0.27067+0.18045+0.09022)
1 - P(x < 5) = 1 - 0.94735 = 0.05265
P(x ≥ 5) = 1 - P(x < 5) = 0.05265
Probability that no emails was received :
x = 0
P(x = 0) = (2^0 *e^-2) / 0!
P(x = 0) = (1 * 0.1353352) / 1 = 0.1353
Answer:
An example of production under the command system in the United States is that of the production of roads and passable roads throughout the nation. In this case, it is the production of a public service, and as such it is controlled by the government in all stages of its production: from the identification of the need, through the tender, the construction authorization and the supervision of the results, everything is controlled by the government. This implies that individuals or private companies cannot by their own initiative create this type of road, but rather depend exclusively on the will of the government.
Answer:
decreased by 4.5%
Explanation:
A family consumes: 10 pizzas, 7 pairs of jeans, and 20 gallons of milk.
In 2016, pizzas cost $10 each, jeans cost $40 per pair, and milk cost $3 per gallon.
The family's total cost of living in 2016 is:
In 2017, pizzas cost $8 each, jeans cost $40 per pair, and milk cost $3 per gallon.
The family's total cost of living in 2017 is:
The change, in percentage, of a typical family's cost of living is:
The cost of living decreased by 4.5%
The company would have 12,247 subsidiary accounts.
<h3>What is a credit?</h3>
A credit is a loan facility granted by a bank or an institution to its customers. This is to enable the customers access funds with a view to paying back at a future date.
Companies or institutions grant credit facilities to encourage their customers plan for their business and then pay back later.
Hence, the company would have 12,247 subsidiary accounts since they extend credits to 12,247 customers.

Transportation costs
can make exporting an inappropriate strategy.
<span>If a product is bulky or heavy, because
of its weight or mass the transportation costs will obviously increase and make it more expensive, and
unless the product carries an extraordinary high value-to-weight ratio the
exporting strategy will be considered the least effective.</span>
