Answer:
Step-by-step explanation:
Economics is a branch of social science and it deals with more of observations, theories, laws, deductions and construction of abstracts model.
So, to do all of these, economists need to be good at mathematics to approach some of these abstracts model.
Like all other scientist, economists also do hypothesis to allow them study the economy growth and help them construct a model that solve this goals these requires a lot of mathematical models and abstract reasoning. They usually employ mathematical and graphical models and analysis to solve the economic issue e.g. demand and supply curves analysis
Economic models usually employ graphical and mathematical analysis to help explain and illustrate such economic processes.
All of these makes economic very hard to study. So to study economics, you need to be good at mathematics
Answer:
Following are the responses to the given question:
Step-by-step explanation:
In the first example, a team walks into a bar & chooses the random person to speak, in which situation, the woman who walks to the club has made a choice, he has selected a people with and who he wants to speak, it is a subjective preference. A choice cannot be random in statistical since it has a subjective preference. The first interpretation may therefore be randomized in general, but not arbitrary in statistics.
In the second example, i.e., the definition of Building tracks Example, a randomized wood piece is an identical piece or is different in size from other pieces. In this, piece wood has been differentiated by one's looks so, when asked to pick a random piece, we are likely to choose a non-uniform part rather than the uniform one. It is a random racial bias, so again in constructing pursuits the second definition could be random, but not a discrete one in stats.
In the identification numbers of random, we intentionally state that equal probability for each unit in the population of inclusion in the sampling. The definition essentially includes all sorts of predilection, and therefore refers to true allegiance, when we neither make that choice nor want to choose a separate unit.

Dina's friend is jealous of Dina's confidence so she wanted to "what up" her :)
Step-by-step explanation:
21/16 which simplifies to 1 and 5/16
You get this by making 1 1/2 a mixed number (3/2). To get 3/2 you do: bottom times the side plus the top---2x1=2+1=3. So 3/2
Then you multiply across:
7x3=21
8x2=16
So 21/16 is your answer
Answer:
2520 in³
Step-by-step explanation:
The volume of a prism is calculated as
V = Ah ( A is the area of the base and h the height )
A =
bh( b is the base and h the height ), thus
A =
× 14 × 18 = 7 × 18 = 126 in²
V = 126 × 20 = 2520 in³
