Answer:

The function of the graph is f(x) = - x² + 2x + 3

Step-by-step explanation:

Using the value of the graph we can say that the the function is negative x² because there are x-intercepts and the y-intercept if above 0.

Using the x-intercepts we can form the function of the graph:

-(x + 1)(x - 3) - we have a negative in front of the two brackets because the function is a negative. Now we multiply out the brackets and the negative at the end:

-(x² - 2x - 3)

- x² + 2x + 3 - So the function of the graph is:

f(x) = - x² + 2x + 3

miskamm [114]

Answer:

12,464 ft

Step-by-step explanation:

I assume that the elevation of the lake is the altitude at the surface of the water.

The surface of the lake is 922 ft above the deepest point of the lake.

11,542 ft + 922 ft = 12,464 ft

Assume that we have two events, A and B, that are mutually exclusive. Assume further that we know P(A) = 0.50 and P(B) = 0.20. (

True [87]

Answer:

a) 0

b) 0

c)No

d) Mutually exclusive event are not independent and when events are independent they cannot be mutually exclusive.

Step-by-step explanation:

From the question,

P(A) = 0.50

P(B) = 0.20.

a) Event A and event B cannot take place at the same time which means they are mutually exclusive, and whenever an event is not possible to take place, then the probability is Zero. Therefore,

P(A ∩ B)= 0

b) CHECK THE ATTACHMENT BELOW

c)No, the reason been that when event are mutually exclusive therefore, they cannot take place at the same time. Because when one event takes place here the other will not take place.

d) Mutually exclusive event are not independent and when events are independent they cannot be mutually exclusive.
