Answer: $5.10
Step-by-step explanation:
14.50 - 4.25 - 5.15 = 5.10
Answer:
The function has two x-intercepts.
The vertex of the function is (one-quarter, negative 6 and one-eighth).
Step-by-step explanation:
Given that the vertex is located at (0.25, -6) and the parabola opens up, the function has two x-intercepts.
f(x) = 2x² - x - 6 has the following coefficients:
a = 2
b = -1
c = -6
x-coordinate of the vertex is:
x = -b/(2a)
x = 1/(2*2) = 1/4
y-coordinate of the vertex is:
f(1/4) = 2(1/4)² - 1/4 - 6 = -6 1/8
Answer:
0.9662 ;
There is a strong positive relationship between the stocks.
Step-by-step explanation:
Given :
Standard deviation of stock X = 4.668
Standard deviation of stock Y = 8.006
Covariance of sample = 36.109
The Correlation Coefficient, r :
(Covariance of Sample (X, Y)) ÷ (standard deviation of X * Standard deviation of Y)
r = 36.109 / (4.668 * 8.006)
r = 36.109 / 37.372008
r = 0.9662
Given the value of the correlation Coefficient, we can infer that there is a strong positive relationship between the two stocks, (X, Y). That is Stock X increases as stock Y increases and vice versa.
