Answer:
D.
Step-by-step explanation:
This function is piece-wise, meaning you will have two equations along with distinct domains. The equation x squared plus 3 illustrates a parabolic curve, while x plus 4 is depicted as a linear function. There is a specific reason why the point on the parabola is open at x equals 4; this signifies that the value does not satisfy the equation. Therefore, x cannot equal 4 for the parabola, so its domain is x less than 4. The closed point on the linear function indicates that when x is 4, it is part of the solution for that equation and graph. Consequently, the domain for the linear function is x greater than or equal to 4. Hope this clarifies things!
The vertex of the graph for the function g(x) = (x- 3)^2 + 9 is located 3 units to the right and 9 units upwards compared to the vertex of the function f(x) = x^2.
Answer: C. Significant at 0.036
Step-by-step explanation:
Given:
Total samples selected Ns= 500
Airplanes that arrived on time Na = 482.
Airplanes that arrived late Nl = 500 - 482 = 18
Calculating the probability of an airplane arriving late:
P(L) = Nl/Ns
P(L) = 18/500
P(L) = 0.036
An event is deemed significant if its probability is equal to or less than 0.05.
As P(L) < 0.05
P(L) = Significant at 0.036
I'm uncertain if this is accurate.
The problem states the dividend per share is 56.25. To calculate the total dividend PRH receives, the total shares owned by PRH should be provided. In any case, the dividend can be found with this formula:
Dividend = 56.25 × (Number of Shares)
In numerical format, this value is represented as 680,010.
In expanded notation, it can be expressed as
600,000 + 80,000 + 10
When written in words, it is described as
Six hundred eighty thousand and ten .
Take into account that the arrangement of the numbers corresponds to each of the forms presented
Six hundred thousand equals 600,000
Eighty thousand equals 80,000
Ten equals 10
