Answer: 20%

Step-by-step explanation:

Human capital refers to the expertise that people gain as a result of working. This includes skills they gain from training and actually working. For instance, the skills a Brainly website designer gets from working on Brainly.

Research suggests that this human capital has led to about a 20% growth in U.S. productivity from the year 1950 to the year 2007 which means that it is a very significant factor in the growth of the country.

Your calculator should give you the answer to both.

3^3 = 3 * 3 * 3 = 27

∛(125) = ∛(5 * 5 * 5) = Three equal factors under a cube root sign give 1 factor on the left of the cube root sign. The other 2 are discarded.

∛(5 * 5 * 5) = 5∛1 = 5

An airline is planning its staffing needs for the next year. If a new route is​ approved, it will hire 858 new employees. If a n
stealth61 [152]

Answer:

E(X) = \sum_{i=1}^n X_i P(X_i)

And from the problem we know the following:

P(X_1) = 0.34 , X_1 =858 represent the condition if the route is approved

P(X_2) = 1-0.34=0.66 , X_1 =157 represent the condition if the route is NOT approved

Then replacing in the formula for the expected value we got:

E(X) = 858*0.34 + 157*0.66 = 395.34

So then the expected number of new employees to be hired by the​ airline based on the conditions given is between 395 and 396.

Step-by-step explanation:

For this cae we can define the random variable X who represent the number of new employees to be hired by the​ airline and we can find the expected value with the following general formula:

E(X) = \sum_{i=1}^n X_i P(X_i)

And from the problem we know the following:

P(X_1) = 0.34 , X_1 =858 represent the condition if the route is approved

P(X_2) = 1-0.34=0.66 , X_1 =157 represent the condition if the route is NOT approved

Then replacing in the formula for the expected value we got:

E(X) = 858*0.34 + 157*0.66 = 395.34

So then the expected number of new employees to be hired by the​ airline based on the conditions given is between 395 and 396.

The diameter of a circle is 2 inches. What is the circle's area?<br>Use 3.14 for<br>square inches​
Afina-wow [57]
It would equal 3.14, because you're using pie (3.14) times the radius (divide the diameter by 2 to get your radius, which would equal 1), and then you square it.
