Answer: See explanation
Step-by-step explanation:
Correlation is a term which simply measures the strength of the linear relationship that exist between two variables that are quantitative.
In the scenario in the question, since the correlation coefficient between the variables is +0.64, it means that there is a positive correlation between the two variables which means there's a positive relationship between the repeated visits to the coffee shop and the customer's age but they're weakly positively correlated .
Answer: <em>x</em>
Step-by-step explanation:
For this equation, the variable <em>y</em> is dependent on the value of<em> x</em>. The value of <em>y</em> changes depending on the value of<em> x</em>. This means that <em>x</em> is the independent variable for this equation.
Answer:
it is a 60 30 90 triangle so basically 2y is = x
21² + y² = x²
441 + y² = x²
y = x/2 (2y = x)
441 + x²/4 = x²
4x² = 1764 + x²
3x² = 1764
x = exact is 24.248711306 simplied square root would just be 14√3
2y = 14√3
y = 7√3
exact wouldd be 12.124355653
Answer: 20
Step-by-step explanation:
Answer:
t = 1
Step-by-step explanation:
1) Subtract 4 from both sides so you get -2t = -2
2) Divide both sides by 2 so you get t = 1
