Answer:
B) There is a correlation between start time and amount of tea consumed. There may or may not be causation. Further studies would have to be done to determine this.
Step-by-step explanation:
Correlation in terms of statistics refers to the relationship that exists between two components. The extent to which the two components or data are related to each other is highlighted with correlation. The change in one component brings the same amount of change in the other component. Correlation discloses the way the variables are related.
In the given excerpt, the correlation between start time and amount of tea consumed has been highlighted. This data is required for further research about the cause.
Answer:
There are currently 50 states in the United States.
The number of states in 1795 in the United States = 15
Now, the fraction of the states that had become a part of the United States by 1795 is given below:
To be able to answer this we need to see the box plots and the rest of the question. Sorry -♡
Answer:
(2x-7y) (2x+7y)
Step-by-step explanation:
4x^2−49y^2
This is the difference of squares
a^2 - b^2 = (a-b) (a+b)
a^2 =4x^2 so a = 2x
b^2 = 49y^2 so b =7y
4x^2−49y^2 = (2x-7y) (2x+7y)
The value of b in the equation is -2
<h3>What is an algebraic equation?</h3>
An algebraic equation is an expression that consists of numbers, variables with their arithmetic operations.
- When solving this kind of algebraic equation, we move the like terms to a side and solve for the variable(unknown).
From the given algebraic equation:
-4b - 5 = 3b + 9
By collecting the like terms, we have:
-4b -3b = 5 + 9
-7b = 14
Divide both sides by (-7)
x = -2
