The correlation coefficient of the data provided is -0.52.
<h3>What is the correlation coefficient?</h3>
Correlation is a measure that is used in statistics to determine the linear relationship that exists between two variables. Correlation can be positive, negative or zero.
Positive correlation is when two variables move in the same direction. Negative correlation is when two variables move in opposite directions. Zero correlation is when there is no relationship between the variables.
Correlation can be determined using a financial calculator. When the financial calculator is used, the correlation coefficient is -0.52

Answer:
29 2/3
Step-by-step explanation:
40 - 10 1/3
Convert the mixed numbers to improper fraction
= 40 - 31/3
Simplifying the above expression,
= 120 - 31 /3
= 89/3
= 29 2/3 carpet yards
Thus from total of 40 yards, 29 2/3 yards of carpet were sold.
If half of 29 2/3 were green carpets sold, thus, 29 2/3 divided by 2 equals 14.83 feet of green carpet were sold.
Answer:
D
Step-by-step explanation:
If (x - 5) is a factor of P(x) then P(5) = 0 ← Factor theorem
Given
P(x) = x³ - 5x² - x + 5, then
P(5) = 5³ - 5(5)² - 5 + 5 = 125 - 125 - 5 + 5 = 0
Since P(5) = 0 then (x - 5) is a factor of P(x)
Answer:
Maximum value is y=24 when x=20
Step-by-step explanation:
The maximum value of the downward parabola is its vertex. Since the vertex is (20,24) then the maximum value is y=24 when x=20
